摘要
目的:评价常规CT扫描对超急性期缺血性脑梗死的诊断价值。方法:回顾性分析50例临床诊断为超急性期缺血性脑梗死的CT扫描征象(发病6 h内)。结果:50例中20例表现为阴性,30例表现为阳性,阳性表现包括脑回肿胀、脑沟变浅或消失;一侧大脑中动脉致密血管征;灰白质界限不清、豆状核征、岛带征;脑组织大片密度减低区。结论:结合典型临床表现,基层医院常规CT平扫可以显著提高超急性期缺血性脑梗死的早期诊断率。
Objective： To evaluate the value of conventional CT in the diagnosis of hyperacute cerebral infarction （HCI）. Methods：The CT findings of 50 patients with HCI clinically confirmed within 6 hours were retrospectively analyzed. Results： Of the 50 cases, non-enhanced CT imaging was negative in 20 cases and positive in 30 cases, the positive signs include cerebral convolution swelling and sulci narrowing or disappearance, ipsilateral hyperdens middle cerebral artery signs, the vague interface of the white and gray matter, the decreased density signs. Conclusions： With the typical clinical presentation, primary hospital routine CT scan can sig- nificantly improve the early diagnosis of HCI.
