Dynamic subtraction CT (DSCT) using a high speed Rotate/Rotate CT Scanner (Toshiba Xforce) was performed on 10 patients with intracranial high density lesions such as brain tumors and vascular malformations. In comparison with conventional contrast enhanced CT, the technique of dynamic subtraction CT enabled us to evaluate more clearly the contrast enhancement of high density lesions and to separate more easily the lesions from hematoma and calcification, which are shown as avascular areas. The results suggest that DSCT is a valuable method for evaluating the contrast enhancement of intracranial high density lesions.
使用高速旋转/旋转CT扫描仪（东芝Xforce）对10例患有脑肿瘤和血管畸形等颅内高密度病变的患者进行了动态减法CT（DSCT）检查。与传统的对比增强CT相比，动态减法CT技术使我们能够更清楚地评估高密度病变的对比增强情况，并更容易将病变与血肿和钙化区分开来，血肿和钙化表现为无血管区域。结果表明，DSCT是评估颅内高密度病变对比增强的一种有价值的方法。
