Abstract
Susceptibility weighted imaging provides a quick snapshot of the state of the brain for existing microbleeds, which may help stratify the
treatment. Finally, (SWI) is an extremely sensitive technique for the detection of hemorrhagic transformation in the early period after onset of acute stroke. So, this study aimed to determine susceptibility weighted magnetic resonance sequence imaging (SWI) accuracy and sensitivity in initial diagnosis of acute cerebral infarction. To elucidate our results, this was a cross sectional study included 40 patients with acute cerebral infarction during the period from May 2020 to May 2022 were consecutively included into our study. All patients included in the study were subjected to: Personal history taking including: Age and sex. Past history taking including: TIA and special habits as smoking. Complaint of the patients including: headache, unilateral weakness, disturbed conscious level and disartheria. General and neurological examinations were carried out by our colleagues.
Results can be summarized as follow: MRI characteristics of acute cerebral infarction; areas of hypointense vessel sign in SWI were found in about 95%. While, 50% had deep white matter ischemia, areas of hyperintensity in FLAIR, restricted diffusion and involutional changes were found in 65%, 85% and 45% respectively. There was a very poor agreement between SWI and FLAIR as regards detection of hypointense vessel sign on MRI scans.
There was significant positive correlation between white matter ischemia, involutional changes and age. Also involutional changes was significantly positively correlated with HTN and TIA. There was significant negative correlation between restricted diffusion in DWI with DM and right sided weakness. Also there was significant negative correlation between involutional changes and obesity.
