摘要
总结经确诊的６０例肝癌、４０例肝血管瘤改良动态ＣＴ扫描的表现，提出鉴别两者的关键在于病变的增强型式：早期呈轻度增强者为肝癌，呈显著增强者应注意是否有延迟增强，有延迟增强者为血管瘤．呈混合型增强者应注意增强灶的密度，与主动脉密度一致者为血管瘤，低于主动脉者为肝癌．另外还应结合延迟扫描，有延迟增强呈等密度充填者为血管瘤，无延迟增强者为肝癌．
A summary is made of the manifestations of dynamic CT scanning which wasperformed on 60 hepatoma and 40 hemangioma patients. The key point of differentiation lies inthe enhance patterns of the lesions. The lesions which show a slight enhancement in early peri-od, are hepatocelluar carcinomas(HCCs).If the lesions take on obvious enhancement , attentionshould be paid to whether there is delayed enhancement, which is the indication of hepatic he-mangioma(HHs ).In the case of mixed enhancement , notice should be given to enhancementdensity, which can be recognized either as HHs if it is as dense as that of the aorta, or as HCCsif it is not. In addition, the differentiation should be combined with delayed scanning. The de-layed enhancement with isodense filling were the features of HHs whereas HCCs possesses no de-layed enhancement. Our conclusion is that the improved dynamic method was simple, easy anddeserving of extensive use.
