目的通过分析超急性期脑梗死的CT征象,提高CT平扫对超急性脑梗死的诊断准确率。方法回顾分析我院63例经临床确诊为超急性脑梗死的病例,均在发病后12h内行CT平扫。结果超急性期脑梗死的CT征象主要有:致密动脉征;脑回肿胀、脑沟变浅;轻度脑白质密度减低。结论CT表现致密动脉征、脑回肿胀及脑沟变浅、轻度脑白质减低对诊断超急性脑梗死有重要价值,结合临床,可对超急性期脑梗死做出正确诊断。 Objective To analyze the CT signs of hyperacute cerebral infarction and improve the diagnostic accuracy of CT scan for hyperacute cerebral infarction. Methods A retrospective analysis of 63 cases of our hospital clinically diagnosed as super-acute cerebral infarction cases, all within 12h after onset CT scan. Results of hyperacute cerebral infarction CT signs are: dense arterial sign; swelling back to the brain, sulci shallow; mild white matter density decreased. Conclusions The CT manifestations of dense arterial sign, swelling of the brain and shallow sulcal groove, mild white matter reduction is of great value in the diagnosis of hyperacute cerebral infarction. Combined with clinical, the correct diagnosis of acute cerebral infarction can be made.
