本文回顾分析了１１５例肝癌的ＣＴ形像特征，发现肝癌病灶如小于５ｃｍ，因其分化程度较好，ＣＴ图像上多呈现圆形结节影，密度均匀，低或稍低；多数病灶（７５％）边缘光整，部分病灶（２８％）有包膜显示，但随着病灶的增大，病变可突破包膜呈浸润性生长；增强后小肝癌和非小肝癌都可使病灶边缘显示清晰。且病灶较平扫有缩小；肝癌在ＣＴ片上还可以发现的有门脉癌栓和／或肝门、胰周、腹腔淋巴结转移的征象。
This article reviewed the CT features of 115 cases of liver cancer, found that liver lesions such as less than 5cm, because of its good degree of differentiation, CT images showed multiple circular nodules, uniform density, low or slightly lower; most lesions (75 (%) marginal consolidation, some lesions (28%) have capsules, but as the lesions increase, the lesions can break through the infiltrating growth of the capsule; enhanced small hepatocellular carcinoma and non-small hepatocellular carcinoma can make the edge of the lesion clear . And the lesions are smaller than the plain scan; liver cancer can also be found in the CT film with portal cancer thrombus and / or hilar, pancreatic, abdominal lymph node metastasis signs.
