Evaluation Of Modified MRI protocol in Diagnosis of Acute Cerebral Stroke Among Sudanese

Abstract

Stroke is one of the major causes of disability and mortality worldwide. The aim of this study is to evaluate of modified MRI protocol in diagnosis of acute cerebral stroke among Sudanese This is a practical study carried out during period from April 2016 to June 2019 and was conducted on 200 patients (male 94, female 106) with average age 47, rang from (17- 84 years). This study was carried out in Alamal National Hospital diagnostic center in Khartoum. The MRI scanner used in this study was PHILIPS (1.5tesla), with 8-channel phased array neurovascular coil. All patients underwent MRI study with different pulse sequences (T2, DWI and FLAIR), and additional modified T2* pulse sequence. All data were entered and analysed using Microsoft Excel including description statistic of frequency tables and graphs. The study showed that the stroke patients with old ages more affected than younger patients , the risk of stroke rises with age after 55years. The preliminary investigations obtained from this study revealed that the patients participated in this study, female‘s (53%) was being more affected than males (47%) in regards with stroke disease. The preliminary investigations obtained from this study revealed that there was difference between the hemispheres , Left hemispheric strokes frequent was 52,(26%) whereas right hemispheric strokes frequent was 23 (11%) ,there was more high incidence of stroke in left side than right side. The results showed that the modified T2* pulse sequence had ability in detection of cerebral micro bleeding rather than other routine sequences. The study conclude that the modified MRI protocol T2* should be the sequence of choice in microbleeding detection for accurate diagnosis of patients with suspected acute cerebral stroke.
