目的评价CT脑动脉高密度征对早期脑梗死的诊断价值。方法回顾分析 53例大脑中动脉分布区急性脑梗死CT脑动脉高密度征的影像资料。结果 2 7例观察到大脑中动脉M1水平段呈高密度征 ,右侧 1 1例 ,左侧 1 3例 ,双侧 3例 ,占收集资料的 53 %。CT对照复查 5例和MRI对照观察1 0例 ,所见均与大脑中动脉高密度征的分布范围相符合。结论大脑中动脉高密度征对脑梗死的早期诊断具有较高的价值
Objective To evaluate the diagnostic value of high density CT cerebral arteries in early cerebral infarction. Methods A retrospective analysis of 53 cases of middle cerebral artery distribution of acute cerebral infarction CT cerebral arterial high density signs of imaging data. Results Twenty-seven cases of middle cerebral artery were observed with high density of M1. There were 11 cases on the right side, 13 cases on the left side and 3 cases on both sides, accounting for 53% of the collected data. 5 cases of CT contrast examination and MRI contrast observation of 10 cases, seen with the middle cerebral artery distribution of high-density sign consistent. Conclusion High-density middle cerebral artery sign has high value in the early diagnosis of cerebral infarction
