Diagnosis of exact etiology of ILD is usually by clinico-radiologic-pathologic correlation. HRCT of Lung plays a crucial role in diagnosis of etiology of ILD &amp; determining prognosis. <strong>Objective:</strong> To describe the HRCT findings in clinically suspected cases of ILD and to compare the role of HRCT with Chest X ray in diagnosis of ILD. <strong>Subjects and Methods: </strong>A descriptive study was conducted among 50 consecutive, consenting patients with clinical suspicion of interstitial lung disease. History and clinical details of all study participants were noted and first examined with chest radiography and then exposed to HRCT. The data thus collected was properly coded and entered in Microsoft Excel and analysis was done using the software SPSS version 16.0. <strong>Results:</strong> Mean age of the study population was 48.84 years (SD=14.46).60% of the study participants were males. Specific diagnoses could be made in 25.7% of abnormal case with radiograph and clinical correlation and in 57% with HRCT and clinical correlation. Most common pattern identified was reticular (60%) and most common anatomical area of involvement identified was lower lobe (54.28%). Most common etiology among the cases was idiopathic pulmonary fibrosis (20%) followed by sarcoidosis (11.4%). <strong>Conclusion: </strong>Idiopathic pulmonary fibrosis, sarcoidosis and Hypersensitivity pneumonitis along with non specific type were the most frequent types of ILD identified in the study. The current study demonstrates a better diagnostic efficacy for HRCT when compared to chest X ray in the evaluation of interstitial lung disease.</p> Sunil M Mishal Mohammed Y Thiruvarul ##submission.copyrightStatement## 2019-03-01 2019-03-01 7 1 01 04 Evaluation of Patients with Blunt Abdominal Injuries by Ultrasonography and Multidetector Computed Tomography. <p><strong>Background: </strong>Blunt abdominal trauma (BAT) usually occurs due to road traffic accidents (RTA), fall from heights or during sports. Prevalence of intraabdominal injury varies widely, ranging from 7.7% to 65%. The aim of study was to evaluate the role of ultrasonography (USG) &amp; multi-detector computed tomography (MDCT) in identifying intra abdominal injury in patients with blunt abdominal trauma and to compare-provide information that could accurately determine choice of management (non-operative vs operative). <strong>Subjects and Methods: </strong>This study was a prospective study; total 50 patients were included in this study. This study was conducted at Department of Radio-Diagnosis, Chalmeda AnandRao Institute of Medical Sciences, Karimagar. The study period was during from October 2015 to September 2017. USG examinations were performed with a curvilinear and linear probe on GE Voluson S6&amp; Philips Envisor C HD. <strong>Results:</strong> A total of 38 cases were positive for intra abdominal injury and 12 cases were negative for intra abdominal injury. 30 patients underwent surgery and the remaining cases were managed conservatively. Most of the patients admitted to this hospital were victims of vehicular accidents. Road traffic accidents (RTAs) as accounting for 33 cases (66%) of the blunt abdominal trauma. <strong>Conclusion: </strong>The present study concluded that MDCT is the superior diagnostic modality in the diagnosis of blunt abdominal trauma. USG can be a valuable initial investigation; however, USG can miss crucial injuries and may lead to inappropriate management in some patients.</p> Ravi Kiran G Harshavardhan NS Anil U Madurwar Santhosh D ##submission.copyrightStatement## 2019-03-01 2019-03-01 7 1 05 08 Role of Ultrasonography in the Era of 3 Tesla MRCP: A Comparative Study in Obstructive Jaundice. <p><strong>Background: </strong>Biliary obstruction is caused by various diseases. In a suspected case of biliary obstruction with clinical and laboratory findings suggestive of obstructive jaundice, the main aim of radiologist is to confirm the presence of obstruction identify its location, extent and probable cause. 3D MRCP virtually demonstrates anatomy of the biliary and pancreatic ducts in 3 Tesla MRI system. Ultrasonography still remains the first imaging modality for obstructive jaundice. The aim of the study was to&nbsp; evaluate the diagnostic efficacy of USG vs. MRCP with 3 Tesla MRI in patients of obstructive jaundice. <strong>Subjects and Methods: </strong>After institutional ethical committee approval, 90 patients confirmed to have features of obstructive jaundice referred for Ultrasonography and MRCP and subsequently underwent ERCP / Surgery were evaluated. It was a Prospective correlational study. Inclusion Criteria were patients with clinical diagnosis of obstructive jaundice referred for Ultrasonography and MRCP and subsequently underwent ERCP / Surgery. Exclusion Criteria were patients non compatible for MRI and other modalities (ERCP), Patients in whom histological diagnosis was not available, Patients unwilling for MRCP / ERCP / Surgery. <strong>Results:</strong> Accuracy of ultrasound was 75 % and MRCP 98 % in detection and delineation of obstructive biliary pathologies. Sensitivity, specificity and accuracy for choledocholithiasis is 80%, 100% &amp; 80% respectively for Ultrasonography and 100% for MRCP. The Sensitivity and Specificity for Ultrasonography was 71% and 100% in detection of biliary obstruction secondary to biliary strictures and for MRCP, the sensitivity and specificity was 100%. Sensitivity and specificity for malignant pathologies in this study was 73 % and 100% respectively on Ultrasonography, while that on MRCP was 93.3% and 100% respectively. <strong>Conclusion: </strong>Ultrasonography as a screening modality is useful to confirm or exclude biliary dilatation and to choose patients for MRCP examination. MRCP is an important non-invasive imaging investigation in the pre-operative evaluation of patients with obstructive jaundice. Magnetic resonance (MR) cholangiopancreatography, combines the advantages of projectional imaging with those of cross-sectional imaging, is an established diagnostic technique. Technical advances over the past decade, including the refinement of 3.0-T imaging capabilities, have added to the usefulness of this noninvasive method. Though MRCP can be considered as the gold standard for diagnostic non-invasive evaluation of the pancreaticobiliary system in cases of obstructive jaundice, ultrasound will always remain the first choice.</p> Vikram Patil Sudha Kiran Das Dr Devkant Rudresh Hiremath Sachin Shetty Vinay Raj ##submission.copyrightStatement## 2019-03-01 2019-03-01 7 1 09 15 MRI Evaluation of Low Back Ache Cases with Radiologic Evidence of Degenerative Lumbar Spine <p><strong>Background: </strong>Back pain is one of the leading cause of occupational disability and limiting factor in performing activities of daily living.Identifying the exact cause of low back ache is a tedious task, but is critical in planning the management of the condition.

Congenital malformations were seen in 10 cases (14.29%) with type I incomplete partition (5.71%) being the most common malformation. <strong>Conclusion: </strong>HRCT of temporal bone is useful in identifying common ear pathologies and anatomical variations prior to the surgery and thereby planning appropriate surgical approach.</p> Lalit Kumar Ankur Malhotra Rajul Rastogi Vijai Pratap ##submission.copyrightStatement## 2019-03-01 2019-03-01 7 1 20 25 Role of Ultrasonography in the Diagnosis of Myocysticercosis <p><strong>Background:</strong> Myocysticercosis is a parasitic infestation caused by encysted larvae of taenia solium. The infection occurs due to ingestion of taenia eggs in raw or undercooked pork, contaminated water or vegetables which are disseminated by hematogenous route to various tissues of the human body. Myocysticercosis occurs due to muscular involvement by the parasite and is more common in population having poor access to sanitation facilities.&nbsp; Ultrasonography is a convenient, easily accessible and cost effective modality which can be used to demonstrate the various appearances of myocysticercosis. FNAC is diagnostic and helpful in identifying the parasite and its body parts. <strong>Aim and Objective:</strong> To evaluate the role of ultrasonogaphy in the diagnosis of myocysticercosis. <strong>Subjects and Methods: </strong>The study was conducted in the Radiology department of Teerthanker Mahaveer Medical College and Research Centre, Moradabad. We included 50 pathologically confirmed cases of myocysticercosis who had undergone ultrasound evaluation by linear ultrasound probe 9L4 of Siemens Acuson S2000 ultrasound machine <strong>Results:</strong> Out of 50 patients that were enrolled in our study , the most common appearance was of well defined cystic lesion of variable size with an&nbsp; eccentric, echogenic scolex. Other appearances include ill defined cystic lesion with or without scolex or a completely calcified myocysticercosis. Most common location was found to be anterior abdominal wall followed by lower extremities, upper extremities and facial muscles subsequently. <strong>Conclusion: </strong>We concluded that ultrasound is an indispensable tool for the diagnosis of mycocysticercosis with characteristic diagnostic appearances.</p> Mohini Chaudhary Deepak Singla Shruti Chandak Ashutosh Kumar Arjit Agarwal Vijai Pratap ##submission.copyrightStatement## 2019-03-17 2019-03-17 7 1 26 28 Role of Assessing Cervical Length by Transvaginal Ultrasound before Induction of Labour <p><strong>Background: </strong>Aims: The study aimed to evaluate the effectiveness of cervical length, measured by transvaginal ultrasound (TVS), to predict successful induction of labor at term and association of cervical length measurements with induction of labor. <strong>Subjects and Methods: </strong>A cross sectional study design was used to collect data was collected from 50 women between 36-40 weeks of gestation who presented at the study institute. Cervical length was measured using transvaginal ultrasound and the association of cervical length with induction of labour was examined. A p value &lt;0.05 was considered as statistically significant. <strong>Results:</strong> Twenty one (51.21%, 95% CI: 36.49, 65.74) of 41 pregnant women had successful induction of labour. The mean cervical length of the 41 study participants was 20.19 ± 5.87 (range 10 to 32) mm. Twenty five women had a cervical length &lt; than 20. Cervical length was associated (X2 test p=0.007) with successful induction of labour. Mean cervical length was significantly different (student t test p=0.0003) between women with successful induction of labour (17.14 ± 3.94 mm) and women with failed induction of labour (23.4 ± 5.92 mm).Cervical length showed slightly good sensitivity (80.95%). It showed a positive predictive value of 68%, negative predictive value of 75% and specificity of 60%. <strong>Conclusion: </strong>Transvaginal ultrasound measures of cervical length before inducing a patient can help to identify women at risk for failed induction and reduce rate of unnecessary caesarean section and complications of prolonged and failed labour after induction.</p> Sherine Marian Chidananda Murthy M Rohit Kumar Sharma Prajwith Rai Francis N.

It is a frequent cause of hospitalization and surgical consultation, representing 20% of all surgical admissions for acute abdominal pain. Objectives: To evaluate the level and cause of intestinal obstruction. Assess the accuracy of imaging findings in correlation with operative findings. <strong>Subjects and Methods: </strong>This is a prospective study of 43 patients who presented with acute intestinal obstruction to our hospital. All the subjects underwent CT scan of abdomen and pelvis in helical multi-detector CT scan machine. The CT scan of abdomen and pelvis findings was compared and correlated with intra-operative findings. <strong>Results:</strong> Out of 43 cases, 28 are males (65%) and 15 are females (35%). Only 17 cases (39.5%) had features of intestinal obstruction on the ultrasonography and only 13 cases (30%) had features of obstruction on abdominal radiography. This study showed 36 patients (83%) had small bowel obstruction and 7 (17%) had large bowel obstruction. In the small bowel, ileum was most common site to be obstructed accounting for about 63.8% of all small bowel obstruction. CT showed 100% correlation with intra-operative findings in assessing the level of obstruction. The most common cause for obstruction is post–operative adhesions which are seen in about 23.2 % cases. <strong>Conclusion: </strong>This study shows that CT is the imaging modality of choice in patients with acute intestinal obstruction to evaluate the level and cause of intestinal obstruction which did correlate well with intra-operative findings.</p> Bysani Swaroop Sindhu N Parthasarathi A Gautam M ##submission.copyrightStatement## 2019-04-03 2019-04-03 7 1 32 36 Is Computed Tomographic Scanning Alters the Management of Patients with Suspected Cholesteatoma? <p><strong>Background: </strong>Cholesteatoma is an abnormal skin growth that can develop in middle section of your ear behind the eardrum; a cholesteatoma may also be caused by a poorly functioning eustachian tube, which is the tube that leads from the back of the nose to the middle of the ear. It causes mainly chorionic ear infection, sinus infection, cold and allergies. This may cause a section of eardrum to be pulled into middle ear, creating a cyst than can turn into cholesteatoma. <strong>Subjects and Methods: </strong>A prospective, analytical study was conducted among 90 patients with complaint of unsafe chronic suppurative otitis media which were randomly selected from outpatient Department of ENT at Shridev Suman Subharti Medical College, Dehradun, Uttarakhand. The patients comprised of both males as well as females and also of different age groups. <strong>Results:</strong> Out of 90 patients, 61(67.22%) were males followed by 29 (32.22%) females. The minimum age of patient in the study was of 8years and the maximum age of patient in study of 50 years. Maximum number of patients belonged to the age group of 11-20 (50%). The mean age in this study was 23 years. Among study subjects, 32 (35.55%) cases had conductive hearing loss, 11(12.22%) cases had sensorineural type, 40(44.44%) had mixed type and 7(7.77%) had no response. Out of 90 study subjects, 46 (51.11%) had cholesteatoma. <strong>Conclusion: </strong>The clinical and radiological findings showed a high level sensitivity with intra operative findings as regards to the presence of cholesteatoma, changes of the ossicular chain and erosion of the lateral semicircular canal. HRCT findings, in the treatment of any congenital abnormality of the ear were a good guide to the surgeon for planning and management.</p> Navin Shukla Varuni Sharma Rakesh Kumar Giri ##submission.copyrightStatement## 2019-03-25 2019-03-25 7 1 37 41 Correlation and Evaluation of the Preoperative Computed Tomography with Preoperative Surgical Findings in Patients with Unsafe Chronic Supppurative Otitis Media <p><strong>Background: </strong>Chronic Suppurative Otitis Media (CSOM) is one of the most common causes of preventable hearing loss especially in developing countries.

Oral cancer is any malignant neoplasm which is found on the lip, floor of the mouth, cheek lining, gingiva, palate or in the tongue. Oral cancer is among the top three types of cancers in India. In India most of the (nearly 90-95%) oral cancers is squamous cell carcinoma. Aim of our study is to detect the Pattern of tumor spread and contribution of CT and MRI in staging of oral cavity. <strong>Subjects and Methods: </strong>In this prospective study we studied 46 patients after proper informed and written consent. Clinical complaints were recorded along with other relevant demographic data. Each patient underwent CT scan and MRI. Results of radiological investigations were correlated with Histopathology. Imaging modalities were used in tumor staging, cervical lymph nodes assessment, bone (mandible) invasion &amp; muscles of tongue invasion. <strong>Results:</strong> We have observed that Oral cavity SCC is more common in the age group of 51-60 years, with male is to female ratio 1.71. Most common location is buccal mucosa and most common risk factor is tobacco chewing. CT scan is less sensitive (67.39%) modality than MRI scan (84.78%) in detection of primary tumor stage; whereas no significant statistical difference is observed in CT and MRI for cervical lymph nodes detection. In detection of mandibular invasion MRI is more sensitive (80.01%) but equally specificity (92.31%) than to CT scan (sensitivity 68.42% &amp; specificity 88.89%). For muscle of tongue invasion MRI is more sensitive and specific (89.47% &amp; 88.89%, respectively) than to CT (sensitivity is 50.01% &amp; specificity is 92.31%). <strong>Conclusion: </strong>CT and MRI are nearly similar in assessing cervical node metastasis. For bone invasion MRI is a superior over CT in our study, but this difference is not significant. MRI was considered superior to CT scan in evaluating the primary tumor extent and muscle of tongue infiltration with significant statistical difference.</p> Sangeeta Saxena Abhishek Gupta Dharmaraj Meena Harshvardhan Khokhar Bhajan Lal Chandraveer Godara ##submission.copyrightStatement## 2019-06-21 2019-06-21 7 1 61 67 Characterisation of Liver Lesions on Triple Phase Computed Tomography and Studying the Social Demographics of the Liver Lesions <p><strong>Background: </strong>To assess and characterize liver lesions using triple phase multi-detector computed tomography (MDCT) as a tool and to study the social demographics of the patients with liver lesions. <strong>Subjects and Methods: </strong>A hospital based retrospective analysis of 150 patients was done on patients with liver lesions who had undergone triple phase MDCT to characterize the liver lesions as was advised post ultrasonography or based on clinical suspicion, in a period of 3 years, from January 2015 to December 2017 in Rajarajeswari medical college and hospital and findings of triple phase MDCT were correlated with clinical/ histopathological or post-operative findings.

The following patterns of knee injuries were seen. Most common injury among cruciate ligaments was ACL tear of which complete tears were more common Posterior cruciate ligament tears were less common. <strong>Conclusion: </strong>Thus, the presence of an anteromedial femoral condyle bone bruise should increase the level of suspicion of a concurrent PLC Knee injury. In addition, we believe that the presence of a posteromedial tibial plateau bone bruise may be a secondary sign of a potential combined PLC injury in the setting of anterior cruciate ligament tear.</p> Priya Gaddgi Modi Anmol Modi ##submission.copyrightStatement## 2019-06-21 2019-06-21 7 1 79 82 Comparison of MRI Findings with Arthroscopy in Knee Injuries <p><strong>Background: </strong>The knee joint can be imaged using a variety of modalities of which MRI is the most recognized technique posing an excellent imaging modality for all the components of the knee joint namely cartilage, ligaments, tendons, menisci, muscles, bone and bone marrow. Injuries to the intra articular structures can be diagnosed with a high degree of sensitivity and specificity. <strong>Subjects and Methods: </strong>Patients with history of pain in the knee with or without swelling where MRI was used as a modality in diagnosing the cause. All patients will be subjected to MR imaging and followed by Arthroscopy. <strong>Results:</strong> Out of the 40 ACLs diagnosed as completely ruptured at MRI, 27 were confirmed to be completely ruptured, 13 were concluded to be partially ruptured and 6 were found to be normal on arthroscopy. An ACL rupture diagnosed on MRI is an important indicator to look for the co – existence of other injuries of that knee joint. Of all the patients accounting for ACL injury ACLs that were classified at MRI as normal were seen to be normal even on arthroscopy. There by giving MRI a negative predictive value of 97.1 percent for ACL injury. <strong>Conclusion: </strong>MRI increases diagnostic confidence and potentially reduces the need for diagnostic arthroscopy.</p> Priya Gaddgi Modi Anmol Modi ##submission.copyrightStatement## 2019-06-21 2019-06-21 7 1 83 86 The Role of Colour Doppler of Carotid Arteries in Cerebrovascular Insufficiency <p><strong>Background: </strong>Cerebrovascular accidents constitute a major cause of adult mortality. The principal indication for cerebrovascular Doppler examination is stroke prevention. Colour Doppler sonography is a sensitive method for detection of atherosclerotic plaque and provide considerable information about the extent and severity of plaque as well as the resulting diminution of arterial lumen. The main strengths of Sonography of carotid arteries are patient comfort, lack of risk and accuracy in detecting carotid stenosis. <strong>Subjects and Methods: </strong>The study was carried out on 40 individuals, among them 20 were symptomatic cases suspected of cerebrovascular insufficiency considered as cases and the other 20 asymptomatic cases with unrelated diseases but having one or the other risk factors for cerebrovascular disease were taken as controls. A detailed clinical history, CNS examination findings and evidence of hypertension, diabetes mellitus, hyperlipidemia and ischemic heart disease were noted. <strong>Results:</strong> Significant stenosis i.e., &gt;40% was found in 12 (60%) of the cases &amp; in 4(20%) asymptomatic controls. Peak systolic velocity ratio showed significant stenosis in 12(60%) of symptomatic cases and in 4(20%) of asymptomatic controls. Plaque characteristics showed 9 hyperechogenic, 8 calcific, 4 low echogenic and 5 moderate or heterogeneous plaques. <strong>Conclusion: </strong>The role of carotid Doppler in detecting the site and morphology of atherosclerotic plaque with quantifying the amount of stenosis is very well justified. In addition carotid Doppler can also be used to assess the prognosis in potential symptomatic and asymptomatic patients with one or the other risk factors for cerebrovascular disease.</p> S Mahbub Pasha ##submission.copyrightStatement## 2019-06-22 2019-06-22 7 1 87 91 Clinical Profile of Patients Subjected for Colour Doppler of Carotid Arteries <p><strong>Background: </strong>The management of asymptomatic carotid disease remains controversial. The finding of a cervical bruit has been used as a marker of carotid disease in asymptomatic patients and studies have suggested that these patients are at an increased risk of TIA and strokes when compared with the age matched controls. Some investigator however feel the risks of stroke is not increased in this patients group but they are at increased risk of death from cardiac diseases. <strong>Subjects and Methods: </strong>The study was carried out on 40 patients. Among them 20 were symptomatic cases suspected of cerebrovascular insufficiency were considered as cases, other 20 asymptomatic individuals with unrelated diseases having one or more risk factors for cerebrovascular disease on the basis of clinical examination and history were taken as controls. <strong>Results:</strong> Out of 10 patients (50%) with atheromatous plaque in carotid bifurcation 3 had on right side (30%), 4 on left side (40%) and 3 on both sides (30%).Among the 4 patients (20%) with atheromatous plaque in common carotid artery, 2 on the right side (50%) and 2 on left side (50%).In 6 patients (30%) with atheromatous plaque in internal carotid artery, 1 (16.6%) had on the right side, 2 on the left side (33.3%) and 3 on both sides (50%). <strong>Conclusion: </strong>Among the 40 individuals, 20 were symptomatic cases suspected of cerebrovascular insufficiency and the other 20 were taken as controls with unrelated diseases having one or more risk factors for cerebrovascular disease. The incidence of male to female ratio of atherosclerotic disease of extracranial carotid system among cases was 3:2, while it was 7:3 among the controls.</p> S Mahbub Pasha ##submission.copyrightStatement## 2019-06-22 2019-06-22 7 1 92 96 Diffusion Weighted MRI – The Diagnostic Modality to Differentiate Renal Pseudotumor from Renal Cell Carcinoma in Chronic Kidney Disease: A Case Report <p>Renal pseudo tumors are rare occurence in patients with chronic kidney disease, most of the times it is detected incidentally on imaging and mimics a renal cell carcinoma. It is imperative to exclude renal cell carcinoma in these patients. A 38-year-old female P2L2A0 presented with menorrhagia, Blood laboratory test revealed elevated creatinine level 2.2 mg/dl. Other blood parameters showed raised urea levels -52, urine protein to creatinine-1.3 and urine protein 1+. Follow up lab values for a period of 3 months revealed persistently raised urea and creatinine levels. MRI with contrast demonstrates small sized bilateral kidneys with parenchymal thinning and multiple well defined lobulated partially exophytic mass lesions, homogenously mildly hyperintense on T2W images, and isointense on T1W images, lesion demonstrated no diffusion restriction on DWI images.</p> Anmol Modi Chanabasappa Chavadi Pallavi Patri ##submission.copyrightStatement## 2019-06-25 2019-06-25 7 1 97 98 Obstructive Jaundice – The Radiological Study in Assessing the Level and Cause <p><strong>Background: </strong>Obstructive jaundice is a common clinical problem. The main objective of the study is to determine the accuracy of MRCP in the evaluation of patients with obstructive jaundice. <strong>Subjects and Methods: </strong>The study was conducted in the department of Radio Diagnosis, MGMC&amp;RI, for a period of 2 years. Thirty three patients were included in the study. All the patients were referred to the department of radio diagnosis with the clinical suspicion of obstructive jaundice and elevated serum bilirubin levels. MRCP was done in all the patients. Three experienced radiologists reviewed the images separately and evaluated the cause and site of obstruction in these patients. The accuracy of each modality was analyzed statistically and correlation was made with the surgical findings or histopathological reports. <strong>Results: </strong>Of the thirty three patients, seventeen patients had benign causes of obstructive jaundice while sixteen patients had malignant causes of obstructive jaundice. MRCP had an accuracy of 97% in detecting the cause of obstructive jaundice. <strong>Conclusion: </strong>With the introduction of MRI guided interventions it may soon be possible in the near future to use MRCP for diagnostic and therapeutic applications in biliary tract and pancreatic pathology.</p> Antony Jean Murali Krishna Prakash Manikka Lakshmanan Annitha Elavarasi Jayamohan ##submission.copyrightStatement## 2019-06-26 2019-06-26 7 1 99 103
