摘　　要：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。CT features of one hundred and fifteen cases with hepatocellular carcinoma were reviewed retrospectively.Those cases of small hepatocelluar carcinoma (SHCC) were round,even density,smooth edge and had false memdrana in most cases.But with growing it changed non -small hepatocallular carcinoma (non-SHCC) and its membrana should be broken.Its edge was vague and irregular necrosis persented in the centre tumor ,The edge of SHCC and non-SHCC showed clear by means of lessen,And there were embolization in portalvein, metastases of lymph nodes around pancreas,liver portal and in abdominal cavity could be found .
