Abstract
Objective: To study the value of diffusion-weighted echo-planar imaging(DW-EPI) of 3.0T MRI on acute intracranial hemorrhage(AIH). Materials and Methods: MRI and CT materials of 29 cases with AIH were reviewed. MRI and CT were performed 24hrs to one week within symptom onset included DW-EPI, routine conventional MR series and axial CT scan. GRE-T2WI was performed on 13 cases of 29 cases. Images of B0(b=0s/mm2), B1000(b=1000s/mm2), CT and GRE-T2WI series were analysed. Results: There were 24(96%), 21(84%), 19(76%) cases that showed positive appearance by B0, B1000 and CT in 25 cases with intraparenchymal hemorrhage, respectively. Seven(100%), 4(57%), 6(86%) cases were detected by B0, B1000 and CT in 7 cases with subarachnoid hemorrhage which involved 3 cases of intraparenchymal hemorrhage associated with intra-ventricular involvement, respectively. All 13 cases with GRE-T2WI got positive outcomes. The ability of detection of AIH with B0, B1000 and CT have no significant difference, statistically. Conclusions: DW-EPI is one of the effective imaging sequences in the diagnosis of AIH and may replace CT scans.
