摘　　要：动态CT是一种新的,有价值的检查技术。本文对8例颅内血管病变(2例动脉瘤、6例动静脉畸形)作了动态CT检查。所有病例均经血管造影检查证实。分析检查结果可见:1.动态CT扫描简便易行,可对门诊病人施行;2.颅内正常血管的时间—密度曲线呈速升速降尖峰型;3.动脉瘤与动静脉畸形的动态曲线与正常血管相同,但峰值明显高于正常血管。动态CT扫描对颅内动脉瘤,动静脉畸形与脑瘤的鉴别有很大价值。Dynamic CT scan is a useful examination technique, and in this report 8 patents (2 aneurysms and 6 AVMS) were studied and confirmed by angiography. The authors are of the opinion that (1) dynamic CT scan can be performed in out-patients; (2) the time-density curve of intracranial vessel is steep in rise and drop down to form a sharp turn, (3) the shape of the curves in aneurysms and AVMs is similar to normal vessels, but the peak values are much higher. Dynamic CT scan is capable of greater distinction between brain tumors and intracranial vascular diseases.
