Globally, stroke is the 2nd leading cause of death and 3rd leading cause of disability. Stroke on an average occurs 15 years earlier among the population in low and middle income countries. This study was done to assess the role of Magnetic Resonance Imaging in the evaluation of stroke with MRI by just doing a few sequences- T1WI, T2WI,FLAIR,SWI,DWI which each takes about 5 minutes, thus saving the precious ‘door to needle time’ we can accurately detect the aetiology of stroke, differentiate acute, subacute and chronic ischemic strokes, salvageable tissue, intra vascular thrombus and guiding in thrombolytic therapy without increasing the risk of radiation exposure to the patient an in case of CT. In our study 100 patients underwent MRI head and majority of patients were in age group 60-69 years. Male preponderance was observed with a M: F ratio of 7:3.About 34% patients had both diabetes mellitus and hypertension. About 45.3% of patients presented clinically with hemiplegia. Infarction was the most common aetiology of stroke seen in 87% most common followed by intracerebral haemorrhage seen in 12% patients. With DWI and ADC sequence the exact age of infarct could be diagnosed and were categorized into four groups based on the time since onset of stroke. 8% cases of hyperacute, 78.1% patients with acute, 9.2% patients had subacute and 4.6% patients had chronic infract were diagnosed. Patients with hyperacute infract as aetiology of stroke showed changes in DWI sequence, whereas 80 patients with acute, subacute and chronic infract as aetiology of stroke showed changes in both T2 and DWI sequences. The results obtained from our study are well comparable with other stroke surveys.
