Assessment of Magnetic Resonance Imaging Role in Diagnostic of Brain Infarction

This study was carried out to assess the Magnetic Resonance Imaging (MRI) role in diagnosis of brain infarction among Sudanese at Khartoum, This study was done at Alzaiem Alazhari University-College of Graduate Studies and Omdurman military hospital and modern medical center, Khartoum, Sudan. This was a descriptive quantitative an observational cross-sectional study of 100 Sudanese patients admitting to all flowing hospitals for brain MRI scan, 50 female and male 50 their ages ranged between [18-80] years,. MRI studies were performed using 1.5 Tesla Toshiba whole body MRI machine. The results of this study revealed that the most common affected site of the lesions was left side, 5 patients [18-27] years, the mean size of brain infarction was [2.20 0.46] mm. In 4 patients [28-37] years, the mean size was [3.30 0.35] mm. In 14 patients [38-47] years, the mean size was [4.30 0.26]. In 19 patients [48-57] years, the mean size was [5.36 0.32] mm. In 29 patients [58-67] years the mean size was [6.24 0.30] mm. In 20 patients [68-77] years the mean size was [7.16 0.29] mm. and in 4 patients [78-87] years, the mean size was [7.97 0.12] mm. The present study concluded that there is a strong correlation between infarction size and age, as age increase the infarction size increase, the right side of the brain is more common site for infarction than the left one. . All four imaging sequence of MRI (T1, T2, FLAIR and DWI) have the same signal intensity for infarction appearance, the result of the study was in line with previous studies.
