Background: "Stroke" is a generic term meaning sudden onset of a neurologic event and is also called cerebrovascular accident or "brain attack". It is one of the leading causes of death globally and is a significant cause of longterm disability. Magnetic resonance imaging (MRI) provides critical informationin acute stroke that can be used to confirm the diagnosis and direct both acute therapeutic interventions and long-term treatment decisions. MRI can identify regions of hemorrhage, active ischemia, and vessel occlusion. This has made SWI a powerful technique in the evaluation ofstroke patients. Materials and Methods: This is a Cross-sectional study was done in the Radiology Department, Subbaiah Institute of Medical Sciences over the period of 1 year. All clinically suspected patients with a neurological deficit (signs and symptoms like dysphasia/aphasia, hemiparalysis/hemiparesis, ataxia, convulsions) were referred by a neurologist, physicians for MRI brain in medical college and general hospital. Results: In this study, out of the 125patients, 115 patients (92%) had infarcts in the arterialterritory, and 10 patients (8%) had venous infarcts. Hemorrhage was detected in 42 patients (33.6%), of which 33 cases were arterialinfarcts and 9 were venous infarcts. Hemorrhage was seen in 27(35%) out of 77 male patients and 15 (31.2%) out of 48female patients. Hypointense blooming was not seen in 83 patients(66.4%) in this study. Occlusion in TOF-MRA was seen in 25(21.7%) patients out of 115 patients. Susceptibility vessel sign is seen in 20 patients out of 25 patients showing occlusion in TOF-MRA. Loss of flow void on T2 indicating thrombus in the vessel was seen in 5 patients. Conclusion Susceptibility weighted imaging is superior than conventional MR imaging in the detection of haemorrhagic transformation of infarct. SWI can also detect the thromboemboli in the vessels by susceptibility vessel sign. SWI indicates the need for doing perfusion MRI to detect penumbra in cases of DWI-SWI mismatch .
