A Study to Assess the Role of Magnetic Resonance Imaging in Cerebral Stroke in a Tertiary Care Hospital

Role of Magnetic Resonance Imaging in Cerebral Stroke

Abstract

Background: Cerebral ischemic stroke remains the leading cause of death and disability in many countries. The objective are: Role of MRI in detection of cerebral ischemic stroke. Age and sex distribution of infarcts in an Indian population. To determine the location and the territory of the involved blood vessels. Subjects and Methods: All patients referred to the Department of Radio-Diagnosis with clinically suspected cerebral ischemic stroke in a period 2019 January to 2020 March at Gadag Institute of Medical Sciences .All MRI scans were performed on a 1.5 Tesla 16 channel GE with HDXT software. Sequences used are T2WI axial and coronal, flair axial, gradient echo axial, T1WI axial, DWI axial and ADC maps. MRA (TOF) circle Willis (neck) and SWI (optional). Results: 50 patients who were studied it was observed that infarction was most common in the age group of more than 60 years with a male dominance, the most common risk factor being Hypertension. The most common clinical presentation was weakness (hemiplegia). MCA territory infarcts were more common with a slight increase on the right side. Both acute and subacute infarcts showed restricted diffusion on DWI with low ADC valves. In the acute infarcts T2 FLAIR was normal, but DWI reflected the changes. Conclusion: MRI is noninvasive and there is no radiation hazard. Excellent grey white matter resolution and multi planar imaging capability of MRI helps in detection of subtle lesions. Sensitivity of MRI to altered water content allows earlier detection of infarcts.
