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，注药后增强扫描和临床资料综合分析作出诊断
In this paper, 50 cases of primary liver cancer, 26 cases of hepatic hemangioma, 15 cases of liver metastases and 9 cases of hepatic cysts were morphologically analyzed and compared; CT value reflecting the lesion density were measured and statistics; enhanced injection after injection Analysis and description. Found the most easily diagnosed CT images of liver cysts. Hepatic cancer lesions were characterized by the edge of the expansive growth of the edge of the clear, there are enveloped, infiltrative growth enhancement after injection of the lesion edge becomes clear, and compared with lesser lesions reduced. Hepatic hemangiomas in the enhanced injection after injection, especially in delayed scanning most of the lesions were filled, which can distinguish between liver and liver cancer and liver metastases. Liver cancer and liver metastases through the morphological characteristics, enhanced injection after injection and comprehensive analysis of clinical data to make a diagnosis
