Comparison Of Mri And Ct For Detection Of Acute Cerebral Haemorrahge

Objective: To compare the diagnostic accuracy of MRI and CT for detection of acute cerebral haemorrahge.Study Design: Comparative StudyPlace and Duration: Mohiuddin Islamic Teaching Hospital Mirpur AJK for period of six months from 1st August, 2020 to 31st January, 2021.Methodology: A total of 20 patients of both genders with age of 25 years and onward with intracerebral hemorrhage who underwent MRI following CT in the first 6 hours of onset and last known well time and admission in stroke center were included in the study. The follow up time duration for both the scans was 24 hours to 48hours. The Mc-Nemar test was used to determine the comparison between MRI and CT on contingency table.Results: The mean age of the participants was 53.26 +/- 2.45. The frequency of the male participants was 13(65%) and that of female was 7(35%). All cases were of acute ICH 20(100%). The number of positive cases on MRI and CT scan was 17, while the frequency of positive cases on MRI and negative on CT scan was 3 with the p- value of less than 0.001 and a confidence interval of 95%. (See table 1 for details). The interrater reliability for acute ICH on MRI is from 0.72 to 0.80 on k statistics. The interrater reliability for acute ICH on CT is from 0.83 to 0.92.Conclusion: It is concluded that the findings of MRI scan were more accurate than CT in the detection of acute intracerebral hemorrhage.
