超急性脑梗死首诊的多层螺旋CT表现

目的 探讨超急性期脑梗死的多层螺旋CT(multislice spiral computed tomography, MSCT)平扫表现.方法 回顾分析确诊的 19例超急性脑梗死病例,所有病例发病后1～6 h内进行第1次MSCT平扫检查,经发病后3 h～5 d复查MSCT或MRI确诊,观察分析MSCT平扫征象.结果 首次诊断超急性脑梗死17例,可疑诊断2例.MSCT平扫阳性表现主要有脑实质低密度征19例,局部脑肿胀征13例,脑动脉高密度征3例.结论 MSCT平扫对超急性脑梗死具有较高诊断价值.

Multi-slice Spiral CT Features of Superacute Cerebral Infarction

Objective To probe multislice spiral computed tomography(MSCT) features of superacute cerebral infarction.Methods 19 cases with superacute cerebral infarction were retrospectively analysed.MSCT scans were performed in all patients at 1～6 h after onset,and the lesions were proved by MSCT or MR at 3 h～5 d after onset.MSCT signs of superacute cerebral infarction were observed.Results 17 cases and 2 cases were diagnosed and suspectively diagnosed with superacute cerebral infarction by CT at first visit of patients.CT features of superacute cerebral infarction included hypodense of cerebral parenchyma in 19 cases,local cerebral swelling in 13 cases and hyperdense sign of cerebral artery in 3 cases.Conclusion MSCT plain scan has significant value in diagnosis of superacute cerebral infarction.
