磁共振DWI在脑部术后早期继发急性脑梗死的应用研究
Application Value of DWI in Patients with Acute Cerebral Infarction Happened Early after Brain Surgery
摘要
Abstract
Objective:To study the application value of DWI in patients with acute cerebral infarction happened early after brain surgery.Method:Conventional MRI and DWI were given to the 764 patients 72 hours after brain surgery for reexamination.The application values of T2WI and DWI in patients with acute cerebral infarction happened early after brain surgery were evaluated.Result:51 patients were finally diagnosed with postoperative acute cerebral infarction,49 cases(96%) occurred in the neighboring area of operative region, 2 cases(4%) occurred in the area far away from the operative region.The diagnostic accuracy of DWI was higher than that of T2WI,the difference was statistically significant(P<0.01).The areas of edema and cerebral infarction showed high signal intensity on the image of T2WI.Secondary acute cerebral infarction showed high signal intensity on the image of DWI,but the area of edema showed low signal intensity on the image of DWI.Conclusion:DWI was superior to T2WI obviously in diagnosing cerebral infarction happened early after brain surgery.It can clearly distinguish cerebral edema and cerebral infarction.It shall be used as a review sequence for the early reexamination after brain surgery.关键词
