目的：探讨慢性硬膜下血肿的CT诊断依据。方法：18例病人中，20个血肿都作了平扫，14例作了增强扫描。结果：平扫可见3种影像：第1种呈高低混合密度；第2种呈凸形的低密度；第3种呈新月形低密度或分隔型低密度。等密度的硬膜下血肿增强扫描："白质塌陷征"及两侧侧脑室前角内移。结论：上述平扫与增强扫描的CT影像是诊断慢性硬膜下血肿的可靠依据。

Objective: To establish the CT diagnostic criteria of chronic subdural haematoma. Methods: In collected 18 cases, 20 heamatomas were given plain scan, and 14 cases was given enhacement scan. Results: Three images were found in plain scan. The first is mixed with low and high density. The second is dumble curiulinear low-density. The third is crescent low-density image or separation image. The equidensity subdural haematoma was given enhancement scan: "collapsed white matter syndrome" and the frontal horn of lateral ventrical is compressed and deformed. Conclusion: The images that we found in plain and enhancement scan are useful to diagnose chronic haematoma.
