AbstractBackground: Stroke is the third leading cause of morbidity in the developed world and it is emerging as a potential public health problem in the developing world as well. The diagnosis of many of the subtypes such as cardio-embolic and athero-thrombotic stroke require detailed clinical, radiological and laboratory evaluation. This study was carried out to correlate the clinical data and radiological findings in cases of stroke. Material and Methods: A total of 1325 patients clinically suspected of having stroke were included in the study. Among 1325 cases, 55 patients with hemispheric symptoms of ischemic stroke were enrolled and subjected to non enhanced CT followed by perfusion analysis (n=25) or CT angiography. Results: Majority of the patients were in the age range of 31-50 yrs constituting 23 (41.8%) of the total with male predominance. Hemiplegia (92.7%) was the commonest presenting symptom with facial nerve as the commonest cranial nerve involvement (12.7%). majority of the patients showed lesions in the internal cerebral artery followed by the middle cerebral artery. Discussion: Radiologist needs to play a more significant role in patient treatment by planning better protocols and studies in investigating the patient rather than following a prescription pattern, as the clinicians are not aware of many innate advantages of certain procedures like perfusion which can be done at the same sitting.
