摘　　要：本文对５０例原发性肝癌、２６例肝血管瘤、１５例肝转移瘤和９例肝囊肿进行了形态学分析和比较；反映病灶密度的ＣＴ值进行测量和统计；注药后增强扫描进行分析和描述。发现ＣＴ图像上最易确诊的是肝囊肿。肝癌病灶边缘有持征，表现膨胀性生长的边缘清晰，可见有包膜，浸润性生长的注药后增强扫描病灶边缘变清晰，并较平扫时病灶有缩小。肝血管瘤在注药后增强扫描，尤其是延迟扫描病变部大部被充添，这可将肝血管与肝癌和肝转移瘤区别开来。而肝癌和肝转移瘤要通过形态学特征。Fifty patients with hepatocellular carcinoma(HCC),thirty six focuses in twenty six patients with hepatic cavernous hemangiomas(HCH),sixty four focuses in fifteen patients with hepatic matastase(HM)and twenty seven focuses in nine patients with hepatic cyst(HY) were analysed and compared. HY was most easy to diagnose with plain CT.HCH could be distinguished from HCC by contrast enhancement and delay. Distinguishing between HCC and HM should depend on multiple clinical materials.
