超急性期脑梗塞的CT诊断价值与MR对照研究

Diagnostic Value of Conventional CT in Hyperacute Cerebral Infarction Compared with MR(DWI)

摘要: <b<目的</b< 探讨常规CT对超急性期脑梗塞的诊断价值。 <b<方法</b< 对比研究28例超急性脑梗塞的CT征象和MR及DWI表现。 <b<结果</b< 常规CT平扫28位患者显示豆状核密度降低24例；局限性脑肿胀11例；大脑中动脉高密度征6例。MR T1WI显示脑肿胀18例；全部病例DWI均显示信号异常。结论常规CT平扫所示的豆状核密度降低，灰白质分界模糊和局部脑肿胀等征象对超急性梗塞的诊断具有一定价值。

Abstract: <b<Objective</b< To discuss the diagnostic value of conventional CT in hyperacute cerebral infarction. <b<Method:</b< The CT feature of 28 cases of hyperacute cerebral infarction were compared with their MR(including DWI) signs. <b<Result:</b< 24 cases showed hypodensity of lengtiform nucleus on conventional CT, while local brain swelling were found in 11 cases, hyperdense middle cerebral artery sign 6 cases. All cases were found abnormal on DWI. <b<Conclusion:</b< The conventional CT were of certain value for the diagnosis of hyperacute cerebral infarction.
