Most patients with PAVM are asymptomatic but it can cause dyspnea on exertion, paradoxical emboli to brain causing various central nervous system complications like stroke and brain abscess, hemoptysis and rupture. The age at the presentation can range from 1st to 7th decade but the majority of patients present before the age of 30 years. PAVM is strongly associated with hereditary haemorrhagic telangiectasis which presents with epistaxis, mucocutaneous telangiectasias and AV malformations of various organs. In our case series, we have patients ranging from 3 yrs to 75 years with presentation ranging from asymptomatic to exertional dyspnea, hemoptysis and neurological complications.</p> 2020-12-30T00:00:00+00:00 Copyright (c) 2020 Author Efficacy of Ultrasound Intrinsic Compression Strain Elastography in Prediction of Malignancy in Thyroid Nodules with Fine Needle Aspiration Cytology Correlation 2021-01-28T10:28:45+00:00 Rapelli Ramakrishna Madhavi Thatipamula <p><strong>Background: </strong>Different diagnostic modalities are used to evaluate and diagnose efficiently thyroid nodules. These include Clinical Examinations, Thyroid Function Test (TFT), Scintiscan, Ultrasonography (USG), Fine Needle Aspiration Cytology (FNAC), and Histopathological examination. However, clinical assessment, TFT and USG have been poor parameters for assessing thyroid nodules. The objective is to this study was aimed to evaluate the efficacy of Ultrasound Elastography for the prediction of malignancy in thyroid nodule. <strong>Subjects and Methods:</strong>After obtaining written informed consent, demographic data such as age, sex and clinical features like, swelling, mode of onset, difficulty in swallowing, difficulty in breathing, hoarseness of voice obtained through an interview and recorded on predesigned and pretested proforma (Annexure II). Further these patients were subjected Grayscale Ultrasound, Ultrasound Elastography and FNAC. <strong>Results: </strong>Malignant lesions were noted in 19 patients on FNAC. Among them, 16 (84.21%) patients had malignant lesions while 3 (15.79%) patients had benign lesions based on combined USE and ECI criteria. This difference was statistically significant (p&lt;0.001). The sensitivity of combined USE and ECI criteria in the diagnosis of malignant lesions was 84.21% with Specificity of 81.69%, PPV 55.17% and NPV 95.08%. <strong>Conclusion: </strong>Based on the findings of this study it may be concluded that, USE as determined by the Ragos criteria, TI RADS score are highly associated with malignant thyroid lesions and useful in differentiating the malignant thyroid lesions from benign ones.</p> 2020-12-30T00:00:00+00:00 Copyright (c) 2020 Author Structural Abnormalities on MRI in Cases with Epilepsy 2021-01-28T10:32:48+00:00 Gaurav Kaushik Madan Manmohan <p><strong>Introduction</strong>: Many treatable anatomical abnormalities of the brain can cause seizures. The present study was done to determine the role of MRI for evaluation of patients with epilepsy. <strong>Subjects and Methods: </strong>Patients who presented to our hospital with history of epilepsy. i.e two or more episodes of unproved seizures 24 hours apart, underwent MRI study to assess for abnormalities. Patients of either gender and all age groups who were referred to our department for MRI study were included. <strong>Results: </strong>Generalized tonic clonic seizures were present in 86% of the population and rest had partial seizures. Using MRI, we arrived at a diagnosis as a cause of seizure in 51.3% of the patients and rest of&nbsp;&nbsp;&nbsp;&nbsp; the 48.7% had a normal MRI study. The most common pathology detected on MRI was infarct with gliosis (24.7%). Less common pathology detected were neurocysticercosis (6.7%), brain atrophy (5.3%), tuberculoma (3.3%), venous thrombosis (2.7%), developmental malformations (2.7%), glioma (1.3%), cavernoma (1.3%), tuberous sclerosis (1.3%), meningioma (0.7%), cerebral abscess (0.7%) and Sturge Weber syndrome (0.7%). Abnormality on MRI was not significantly associated with gender or type of seizure. MR abnormality was observed maximum in patients between 1 to 30 years (30 out of 70 patients i.e. 42.8%) while all the elderly cases showed abnormal MRI, with infract with gliosis being the most common finding. <strong>Conclusions : </strong>MR imaging should be the first investigation of choice in epileptic syndrome, cerebrovascular disease with seizure, developmental cortical malformations, and vascular malformations.</p> 2020-12-30T00:00:00+00:00 Copyright (c) 2020 Author Radiomics & Radiology: A Critical Step towards Integrated Healthcare 2021-01-28T10:37:30+00:00 Mayur Pankhania Aditya Mehta <p>Radiomics have shown great promise for integrated healthcare. Radiomics is defined as high-performance retrieval of significant volumes of characteristics from images and conversion of images to higher-dimensional data and subsequently mining for improved support for therapeutic judgements. It has its roots within Computer-Aided Detection (CAD)or Computer-Aided Diagnosis (CADx); it is unique in many aspects. It does not just detect and diagnose but also ventures into therapeutic, prediction, projection and modelling that can be used to generalize and reproduced. It has great potential in creating a paradigm shift in the way healthcare is delivered and perceived. We will review and outline the stage of radiomics&amp; its SWOT analysis, exclusively addressing application in medical imaging and spotlighting the technical issues.</p> 2020-12-30T00:00:00+00:00 Copyright (c) 2020 Author Plain X-Ray and MRI Evaluation of Painful Hip Joint 2021-01-28T10:39:53+00:00 S. Althaf Ali Dwara Manojna Devi <p><strong>Background: </strong>Hip joint pain is a frequent problem in current practice and can be due to different causes since the investigations are invariably used to diagnose the source of the injury. The primary examination is accompanied by MRI, which is a valuable instrument in hip disease evaluation since it requires a detailed study of articular cartilage, epiphysis, joint fluids, bone marrow and extra-articular soft tissue which may be impaired by hip disease. <strong>Subjects and Methods: </strong>In a total of 60 individuals who had hip joint pain and subsequently had plain radiographs accompanied by the hip joint MRI was studied in a prospective cross-sectional analysis. The data is interpreted and the results of basic X-rays are compared to the MRI. <strong>Results: </strong>Of the 70 cases the males (67%) are commonly affected than females (33%). The majority of the patients fall under the age group of 31-40 years (28.33%). In our study, we find the commonest pathology for the hip joint pain is AVN of femoral&nbsp; head 20 cases (28.57%), followed by joint effusion 15 cases (21.42%), Osteoarthritis 13 cases (18.57%), TB hip 10 cases (14.28%), Perthes 4 cases (5.71%), DDH 4 cases (5.71%) and metastatic disease 4 cases (5.71%). Of the twenty AVN cases, only 6 (30%) are found on a plain x-ray whereas all 20 (100%) are detected on MRI. Similarly, out of 15 cases diagnosed as joint effusion, only 5cases (33.33%) are detected on plain radiograph, but all the 12 cases (100%) are detected on MRI. The remaining 100% pathologies are observed on X-ray and MRI; moreover, MRI helps to improve the identification of articular cartilage, epiphysis, and additional soft tissue articular anomalies. <strong>Conclusion: </strong>MRI is a better way to identify joint effusion and synovial proliferation. Unlike standard x-rays. In proven cases with clear radiography such as Perthe’s and metastatic disease, Hip MRI helps to enhance disease staging, clinical implication, and soft tissue expansion.</p> 2020-12-30T00:00:00+00:00 Copyright (c) 2020 Author Reversible Posterior Leukoencephalopathy Syndrome (RPLS) in Late Onset Postpartum Eclampsia- A Retrospective Study 2021-01-28T10:43:32+00:00 Vikrant Kanagaraju B Devanand <p><strong>Background: </strong>Reversible posterior leukoencephalopathy syndrome (RPLS) or Posterior reversible encephalopathy syndrome (PRES) is a unique clinicoradiologic entity characterized by acute onset headache, seizures, blindness and altered mental state associated with reversible vasogenic edema of the brain. It is a major complication of eclampsia, but data on clinicoradiological features of PRES in late-onset postpartum eclampsia are scarce. The objective is to analyze the clinicoradiologic features and outcome in a cohort of late postpartum eclampsia patients with PRES. <strong>Subjects and Methods: </strong>Eighteen patients of late postpartum eclampsia with clinical as well as neuroimaging features consistent with PRES were included in this retrospective study. All had undergone magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) and apparent diffusion coefficient(ADC) mapping. Data on age, antepartum history, peak systolic and diastolic blood pressures, clinical features, time to neuroimaging, location of lesions on brain imaging and presence of associated ischemia or hemorrhage in MRI were collected and analyzed. <strong>Results: </strong>The mean age was 25.72 3.23 years. The average duration between labor and clinical symptoms was 8.5 days. 13/18 patients (72.2%) had elevated blood pressure at admission. Mean systolic and diastolic blood pressures were 143.88 (120-180) and 93.88 (80-100) mm Hg respectively. Headache was the presenting feature in 16 patients. The parieto-occipital regions were the most frequently involved followed by the cerebellum (7/18) and frontal lobe (4/18). Atypical regions were not involved. Clinical recovery had been noted in all. <strong>Conclusion: </strong>PRES associated with late postpartum eclampsia, an entity of limited awareness can present without antecedent preeclampsia. Radiological changes are the key to early diagnosis.</p> 2020-12-30T00:00:00+00:00 Copyright (c) 2020 Author Assess the Role of Sonography and MRI in Diagnosing Ovarian Masses 2021-01-28T10:48:00+00:00 G. Mahender Reddy M. L. Ravindernath S.Snehaja Reddy <p><strong>Background: </strong>In order to conduct appropriate surgical treatments, the characterization of ovarian lesions is of considerable significance and can affect patient care. A multidisciplinary approach based on physical assessment, laboratory tests and imaging techniques includes adequate measurement of the adnexal masses. The aim is to assess the role of Sonography and MR in diagnosing ovarian masses, to study imaging characteristics of ovarian masses on USG and Doppler in correlating these findings with MR features. <strong>Subjects and Methods: </strong>The present study was carried out in the department of radiodiagnosis to determine the efficacy of sonography and MRI in the diagnosis of ovarian masses. The study group comprised 50 patients with clinically suspected ovarian masses and imaging was carried out on all patients with ovarian masses and imaging was carried out on all patients with ovarian masses. All the masses were evaluated on sonography based on the Sassone scoring system. Morphological analysis was performed for each mass based on wall thickness, inner wall structure, septal structure and echogenicity of mass. The color flow was carried out, subsequently; MRI was carried out for each patient. Radiological diagnosis was confirmed after surgery on histopathological examination. <strong>Results</strong>: The majority of the patients were in the age group of 31-40 years. The most common symptoms noted were pain in the abdomen. The most common clinical finding was a palpable mass. The application of Sassone sonomorphologic score &gt;9 was identified in 8 masses, out of which 7 were malignant and 1 was a benign lesion. The colour flow was detected in 38 out of 50 masses. The presence of flow, type of flow, vessel arrangement, morphology and location were noted and on pulsed Doppler the RI and PI values were calculated. Out of 8 malignant cases, 5 were diagnosed as malignant according to the Caruso score. The overall sensitivity 100 %, specificity is 97.6% and diagnostic accuracy is 98% of MRI which is higher than that of ultrasound and CDS. <strong>Conclusion</strong>: We conclude that MRI is a superior diagnostic modality in establishing the diagnosis of ovarian masses.</p> 2020-12-30T00:00:00+00:00 Copyright (c) 2020 Author 3D Printed Model of Airway for Clinical Simulation 2021-01-28T10:54:17+00:00 Maheswaran Viyannan Pananghat A. Kumar Sreedharkumar Eswarswamy Gunaseelan Murugesan Karthikeyan Ramaraju <p><strong>Background: </strong>The present medical curriculum aims at training the students to be proficient in performing techniques required for clinical practice. This is best achieved through clinical simulation, which has emerged as a successful method for clinical learning. Residents in respiratory medicine need to be trained in the procedure of bronchoscopy for which a functional model of the airway is required. Airway mannequins for this purpose can be produced using 3D printing technology, which involves the usage of sophisticated software. <strong>Subjects and Methods: </strong>Serial axial CT images of the chest, revealing details of the respiratory tract were selected as the base resource to recreate the bronchial tree by 3D printing. This DICOM (Digital Imaging and Communications in Medicine) images after conversion into STL (Stero lithography) format were transferred into a 3D printer and physical models were made from these data, using Vero clear and rubber. This model which had a life-like form and consistency required for practicing the skill was connected to an airway mannequin using an adaptor to practice the skill. <strong>Conclusions: </strong>Axial CT scan images provide the base data for reconstructing the airway of a patient, using 3D printing technology and appropriate software. Such reconstructions can be used to produce a functional model of the airway, which can be used for training in bronchoscopy. The training system could be connected to a monitor thereby facilitating tracking of the probe of the bronchoscope. Repeated trials make the trainees perfect their technique. Our attempt to replicating the tracheobronchial tree for such training has been a success.</p> 2020-12-30T00:00:00+00:00 Copyright (c) 2020 Author Computed Tomography Evaluation of Blunt Abdominal Injury 2021-01-28T10:56:20+00:00 Sholy K Vareed Don Paul Mathew Justine Antony <p><strong>Background: </strong>Unlike penetrating abdominal trauma, where management is largely determined clinically, the diagnosis of blunt abdominal injury by clinical examination is unreliable, particularly in patients with a decreased level of consciousness.Plain abdominal radiography has limited role in the assessment of blunt abdominal trauma, although some authorities continue to advocate its use. CT scan’s main advantage is the ability to detect arterial contrast extravasation, uncontained or as a pseudoaneurysm, which predicts the need for surgery or angioembolisation. The aim is to study computed tomography evaluation of blunt abdominal injury. <strong>Subjects and Methods: </strong>The present study was conducted in the Department of Radiology of the medical institution. For the study, we used abdomen CT scan reports of 100 patients with BAT, who were stable enough to undergo radiological investigation. The patients included 66 males and 34 females. All CT scans were obtained with a 16 slice MDCT Scanner (Siemens). All patients received intravenous bolus of iodinated contrast agents. Individual organ injuries were graded according to the American Association for the Surgery of Trauma (AAST - OIS) injury scoring scale. The overall imaging findings were analysed for their role in guiding the therapeutic options, whether conservative or surgical. <strong>Results: </strong>Total number of patients included in the study was 100. The mean age of patients was 41.97 years. Number of male patients was 66 and number of female patients was 34. For the mode of injury, other miscellaneous causes were most common in out study group followed by road traffic accidents. It was observed that OIS grade II patients were 19, OIS grade III patients were 29, OIS grade IV patients were 12 and OIS grade V patients were 10. The highest proportion of conservatively managed patients were seen in OIS grade II patients. <strong>Conclusion: </strong>Within the limitations of the present study, it can be concluded that CT scan for blunt abdominal injury is a reliable and accurate method for diagnosis. It has all the qualities to make it a gold standard for initial investigation of choice for blunt abdominal injury patients.</p> 2020-12-30T00:00:00+00:00 Copyright (c) 2020 Author Imaging Findings in Late-Onset Rectal and Vesical Bleed in Patients Who Have Undergone Radiation Therapy for Pelvic Neoplasms 2021-01-28T10:58:25+00:00 Jagadeesh Pasupuleti Yugandhar Samireddypalle Guntaka Srujana Ramavath Ravi Naik Sabarinath Eada K.S. Vedaraju <p>Radiation-induced vessel injury is described more than a century ago and remains a persistent clinical problem, despite advances in the field of radiation oncology. Treatment of pelvic neoplasms with radiotherapy may result in chronic radiation toxicity, especially Haemorrhagic radiation cystitis and chronic radiation proctitis. We discussed the computed tomography (CT) findings of three cases with a history of radiotherapy to the pelvis presenting with hematuria and hematochezia. Contrast-enhanced CT could diagnose the cause and site of bleed. All these patients were managed successfully by endoscopic coagulation.</p> 2020-12-30T00:00:00+00:00 Copyright (c) 2020 Author Portable Chest X – Ray in COVID -19 Positive Cases in a Tertiary Care Centre in Central India. (A Retrospective Analysis of 739 Cases) 2021-01-28T11:03:42+00:00 Priyal Chouhan Pranav Kumar Dave Monika Puranik Krati Khandelwal Vivek Gupta Rakesh Mishra Megha Jain <p>–PCR. Portable chest radiography is the first imaging modality that can be used to detect lung abnormalities and get follow up when required. Radiological findings observed in various CXR are ground-glass opacity/haziness, Consolidations, Peripheral air space opacities, diffuse air space involvement, and uncommon findings – pleural effusion, cavitation, pneumothorax, subcutaneous emphysema and pneumomediastinum. Use of Portable CXR is helpful to avoid transport of patients to CT room and subsequently avoid frequent decontamination of the CT room. Portable CXR is of much value where CT facility is not available and its use reduces radiation dose to patients and radiation staff. The objective is to analyze chest X-ray findings in proven cases of COVID -19 as per classification of British Society of Thoracic Imaging (BSTI) in the form of various radiological patterns and severity assessment. <strong>Subjects and Methods: </strong>This is a retrospective study of chest x-ray of COVID-19 positive patients, confirmed by RT-PCR and was admitted to designate COVID center: LNMC and JK Hospital, Bhopal in the duration of 31 July 2020 to 31 Aug 2020. Chest X-ray of 739 patients was studied and the mean age group was calculated. Lung involvement and pattern of distribution of disease were analyzed and classified according to BSTI classification and documented in frequencies and percentages. <strong>Results</strong>: In our retrospective analysis of a total of 739 CXR of which the number of males was 457 (61.84% ) and the number of females was 282 (38.16%). The average age group was ranging from 0 (1month) year age to 90 years age with the mean age group of 41 to 50 (20.2%). The mean age of the patients was 40.5 years. 393 (53.1%) patients have normal chest radiographs. <strong>Conclusion:</strong>The radiological findings in patients with COVID-19 infection varies with the severity of the disease. In the early phase of the disease, CXR was normal. The most common findings are basal / lower lobe consolidation more on right, followed by ground glass densities, peripheral air space densities, diffuse airspace disease. Basal / lower lobe consolidation was the usual findings in the mild category. In the moderate category, a variable pattern of all findings was seen. In the severe category of disease, diffuse air space densities and peripheral air space opacities were seen. Pleural effusion is the least seen.</p> 2020-12-30T00:00:00+00:00 Copyright (c) 2020 Author Computed Tomography Angiography Evaluation of Peripheral Arterial Disease and Correlation with Colour Doppler 2021-01-28T11:07:19+00:00 M.

Magnetic resonance (MR) imaging is a powerful diagnostic tool that can be used to help evaluate spinal infection and to help distinguish between an infection and other clinical conditions. Aim of the current study is to evaluate various spectrum and types of spinal infections, and discussing the role of MRI in diagnosing them and their characterization. <strong>Subjects &amp; Methods: </strong>This Hospital-based prospective study consists 30 patients with clinically suspected spinal infections and chronic non-resolving low backache referred to the department of Radiodiagnosis in a period of 2 years. Investigations include Complete blood count, ESR, sputum analysis for acid-fast bacilli and MRI of the spine. <strong>Results: </strong>20 cases involved the lumbar spine, of which 12 were tubercular, seven were pyogenic, and one case was actinomycosis. In total 21 tubercular cases, 12 cases involved lumbar spine (57%), 8 cases affects the thoracic spine (38%), and 1 case involves the cervical spine (P = 0.562). the incidence of spondylodiscitis is common overall in the lumbar spine. 23.8% of tubercular and 12.5 %of pyogenic cases involved more than two vertebrae. T1 hypointensity is seen in 18 cases of tuberculosis (85%), 8 cases of pyogenic (75%), and 1 case of actinomycosis (100%) (P = 0.801). 4 cases showed preservation of disc height, among which three are tubercular (75%), and 1 was actinomycosis (25%). 85 % of tubercular and 100% of pyogenic cases showed disc narrowing. 81 % of tubercular and 100 % of pyogenic cases showed disc hyperintensity. Nine cases of tuberculosis (42.9%) and 3 cases of pyogenic (37.5 %) showed epidural abscess. 26 cases showed para vertebral extension of which 18 were tubercular (69.2 %), 7 were pyogenic (26.9 %) and 1 was actinomycosis (3.8 %). 94% of tubercular and 42 % of pyogenic abscesses showed a well-defined para spinal signal in cases of paraspinal extension. 15 of the 18(83%) tuberculosis, 3 of the 7 (42%)cases of pyogenic, and 1 case of actinomycosis showed subligamentous spread along more than three vertebrae. Heterogenous enhancement was noted in 12 of the 15 (80%) tubercular cases, 1 of the 3 (33%) pyogenic cases, and 1(100%) actinomycosis case. 71% tubercular cases and 2 of 8 (25%) cases showed predominant anterior 2/3<em><sup>rd</sup> </em>involvement. Grade III or more (&gt;50%) vertebral destruction was seen in 16 tubercular (76%) and 2 pyogenic cases (25%). Six cases showed skip lesions of which 5were tubercular and 1 was pyogenic. 5 of the 21 (23.8%) tubercular and 1 of the 8 (12.5%) pyogenic cases showed skip lesions. <strong>Conclusion: </strong>Awareness of atypical MR imaging at early infectious spondylitis is important to avoid diagnostic delay and unnecessary other diagnostic procedures. Several non-infectious conditions may simulate the spinal infections. Hence It is helpful to be aware of these diseases and their MR imaging features. With these points in mind, MR imaging can be very beneficial to patients with spinal infection.&nbsp;</p> 2020-12-31T00:00:00+00:00 Copyright (c) 2020 Author Lung Ultrasonography and Chest Radiography in Suspected Cases of Pneumonia in Critically Ill Patients- A Comparative Study 2021-01-28T11:12:11+00:00 Bharat M.P Deepak K.S <p><strong>Background: </strong>The present study compared lung ultrasound (USG) and chest radiography in suspected cases of pneumonia in critically ill patients. <strong>Subjects &amp; Methods: </strong>56 patients age above 20 years of age of both genders diagnosed with pneumonia were included.

CAD systems are a new tool in detecting breast cancers on screening mammograms and in detecting potentially suspicious abnormalities on a mammogram. The aim &amp; objective is to main aim of the present study to evaluate the performance of Computer Aided Detection using Full Field Digital Mammography in Breast Cancer imaging. <strong>Subjects and Methods:</strong>In the present study, Cases with lump breast with clinical suspicion of breast cancer and post op recurrence of breast cancer were imaged with FFDM and images were read on the viewing monitor without and with the aid of CAD software. The present study confirms that the diagnosis of breast cancer is made only following histopathology of respected specimen. <strong>Results: </strong>The maximum incidence was in 41-50 years and 51-60 years which was 13 cases in each group (30 %). There were 25 cases out of 40 (62.5%) in which the lesion was marked by CAD. Out of which in 20 cases (50%) only one lesion was marked by CAD and in 4 cases (10%) two lesions were marked by CAD. The total number of lesions marked by CAD was 25 (62.5%). Majority of patients had scattered fibro glandular density of breast. This was present in 19 patients (47.5%). 10 patients (20%) had heterogeneously dense breast, 07 patients (17.5%) had fatty breast and 04 patients (10%) had extremely dense breast. In majority of cases the lesion type was mass alone which was present in 26 cases (60%). While 10 cases (25%) presented as mass with microcalcifications and 4 cases (10%) presented with microcalcifications alone. In 24 cases there was no spread of cluster of micro calcification (60%). In 7 cases (17.5%) the spread of cluster of micro calcification was &lt;10mm, in 4 cases (10%) the spread of cluster of micro calcification was 21-30 mm and in 5 cases ( 12.5%) the spread of cluster of micro calcification was &gt; 40mm. In majority of cases the HPE revealed DCIS which was seen in 22 cases (55%), 08 cases (20%) were invasive ductal carcinoma and 02 cases was invasive lobular carcinoma. In 22 cases (55%) the BIRADS for the breast affected with cancer was BIRADS-V. While in 14 cases (35%) the score was BIRADS-IV, 04 cases (10%) the score was BIRADS-VI and in 02 case (5%) the score was BIRADS-III. The sensitivity, specificity and accuracy of CAD for detection of mass were 70%, 100% and 85% respectively and for detection of cluster of microcalcification were 100% respectively. <strong>Conclusion: </strong>CAD with FFDM is good at detection of Microcalcifications. Detection of masses is better without the aid of CAD as compared to CAD. However detection of lesion improves if reading of mammogram is done both with and without CAD.</p> 2020-12-31T00:00:00+00:00 Copyright (c) 2020 Author Carotid Artery Intimal Medial thickness in Diabetic and Non-Diabetic Subjects in Central Kerala 2021-01-28T11:18:52+00:00 Sholy K Vareed Don Paul Mathew P Suresh <p><strong>Background: </strong>Increase in intimal medial thickness (IMT) of the carotid arteries is contemplated as a guide to atherosclerotic vascular disease and subclinical organ damage and foretell cardiovascular disease.

Common carotid artery (CCA) IMT was calculated using a linear probe of a high-resolution ultrasound medical system. <strong>Results</strong>: Diabetic subjects (0.95 mm) showed significantly higher mean intimal medial thickness (IMT) when compared non-diabetic subjects (0.85 mm) (p &lt;0.05)<strong>. </strong>Correlation of IMT was seen with age, total cholesterol, triglycerides, HDL &amp; LDL cholesterol and systolic blood pressure (SBP) in diabetic subjects. Total cholesterol, SBP and diastolic blood pressure (DBP) showed a correlation with IMT in the non-diabetic subjects. Age, total cholesterol, SBP, and diabetes were independent risk factors for intimal medial thickness in multivariate linear regression analysis. <strong>Conclusion</strong>: Higher intimal medial thickness was seen in diabetic subjects when compared to non-diabetic subjects. We conclude that age, total cholesterol, SBP and duration of diabetes showed a significant correlation with IMT. IMT can be considered as a screening tool in diabetic patients for the early detection of atherosclerosis.</p> 2020-12-31T00:00:00+00:00 Copyright (c) 2020 Author Comparative Study of Ultrasound and Magnetic Resonance Imaging of Adnexal Masses 2021-01-28T11:19:51+00:00 Narikelapu Nitya Rama Krishna Rao Baru <p><strong>Background</strong>: Current study aimed to assess the role of ultrasound and MRI in the evaluation of adnexal mass lesions and comparison with clinical outcomes. <strong>Subjects &amp; Methods: </strong>A total of 30 suspected adnexal mass detected on ultrasonography was performed MRI, and accuracy of both USG and MRI were compared with histopathology. <strong>Results: </strong>Abdominal pain was predominantly confined to the lower abdomen in13 of 30 cases (43.3%). On USG total number of benign lesions was 19, and the total number of malignancies was 11. However, on MRI, 21&nbsp; cases were mild, and 9 cases were malignant. six cases were diagnosed as malignant in ultrasound. In these six cases, two cases were serous cystadenocarcinoma, two were mucinous cystadenocarcinoma, one was serious papillary cystadenocarcinoma of the fallopian tube, and one was a malignant tubo-ovarian mass. MRI accurately diagnosed 4 indeterminate cases that correlated with the histopathology report. 9 malignant lesions were diagnosed as malignant by MRI were 3 cases of serous cystadenocarcinoma, 2 cases of mucinous cystadenocarcinoma, 1 case of malignant tubo-ovarian mass, 1 case of endometrioid carcinoma, 1 case of serous papillary cystadenocarcinoma of the fallopian tube and 2 cases of malignant sex cord-stromal neoplasms. Both the cases of serous cystadenomas were correctly diagnosed as benign lesions on both ultrasound and MRI. There were 2 cases of mucinous cystadenocarcinoma, which were accurately diagnosed as malignant on both USG and MRI due to the presence of solid components, mural thickening. The sensitivity, specificity, and accuracy of USG were 36.6%, 94% and 55% respectively. The sensitivity, specificity, and accuracy of MRI were 81.80%, 94.7%, and 65.7%, respectively. <strong>Conclusion: </strong>The best agreement was observed between MR findings and diagnosis in origin, tissue content, and tissue characteristics. Sonography had a weak correlation in context to the definitive diagnosis for the origin and tissue content of a mass.</p> 2020-12-31T00:00:00+00:00 Copyright (c) 2020 Author Role of Dynamic Contrast Enhanced Magnetic Resonance Imaging and Mammogram in Evaluation of Breast Lesions with Pathological Correlation 2021-01-28T11:21:40+00:00 K Harsha Veena Ramakrishna Rao Baru <p><strong>Background</strong>: To perform mammography and dynamic contrast enhanced MRI in patients with clinically suspicious breast lumps and correlating the findings with pathology in patients of positive imaging. <strong>Subjects and Methods</strong>: total of 40 patients evaluated through MRI BI-RADS lexicon (General Electric Medical Systems) at 1.5T in combination with dynamic kinetic analysis of time and signal curves for lesion characterization. <strong>Results</strong>: The mean age was 44 years, maximum of patients (n=22) belongs to age group of 41-60 years (52.5%). Five lesions showed dark internal septations, as benign. 11 lesions (33.5%) showed heterogenous enhancement, as malignant. Early rim enhancement is observed in 3 lesions (9%). Out of which two of them were proven to be malignant and one lesion was an infective abscess. Invasive Duct Cell Carcinoma was the common histology in the malignant lesions, observed in 13 out of 18 (72.2%). Fibroadenoma was the common benign breast lesion, observed in 8 out of 19 (42.1%). In 4 post operative patients, 2 (50%) were post operative fibrosis, 1 (25%) was recurrence and 1 (25%) was post operative collection. In 18 malignant lesions, 11 patients (61.1%) had skin retraction, 10 patients (55.5%) had skin thickening, 9 patients (50%) had axillary lymphadenopathy, 2 patients (11.1%) had nipple retraction, and one patient (5.6%) had pectoralis involvement. In our study, MR imaging alone has Sensitivity of 88.8%, specificity of 86.3%, PPV of 84.2%, and NPV of 90.4% with Accuracy 87.5%. <strong>Conclusion : </strong>The dynamic contrast enhanced MRI is important tool to evaluate the postoperative breast in differentiating between benign postoperative changes. By combining kinetic analysis with morphological analysis it add benefit to categorise the breast lesions into benign and malignant with increased confidence levels. CE-MRI with both morphology and kinetic curve assessment has a Sensitivity of 94.5%, Specificity of 100% with Accuracy of 97.5%.</p> 2020-12-31T00:00:00+00:00 Copyright (c) 2020 Author A Comparative Efficacy of MDCT Angiography and Colour Doppler Ultrasonography in Diagnosing Peripheral Arterial Disease in the Lower Limb 2021-01-28T11:24:25+00:00 M B Naveen Raj A. R Omprakash <p><strong>Background: </strong>Imaging plays a crucial role in the management of patients with peripheral arterial disease. The present study compared colour Doppler ultrasonography findings with MDCT angiography in patients with peripheral arterial disease in the lower extremity. <strong>Subjects and Methods : </strong>40 patients with signs and symptoms of peripheral arterial occlusive disease referred for evaluation by imaging by colour doppler ultrasonography and MDCT angiography were studied. <strong>Results: </strong>There was statistically significant difference in the detection of the extent of segment involvement in DFA. There is significant difference in the detection of the extent of segment involvement in popliteal artery. There is statistically extremely significant difference in the detection of the extent of segment involvement in ATA. <strong>Conclusion: </strong>MDCT is better than Doppler in detecting the length of stenosis in the arterial system. MDCT is better than Doppler in detecting the presence of thrombosis especially in the infra-popliteal segment. Even though MDCT is not statistically significant than Doppler in detecting the number of collateral segments , as the arterial tree is better delineated in MDCT.</p> 2020-12-31T00:00:00+00:00 Copyright (c) 2020 Author
