目的探讨ＣＴ对肝脏占位性病变的诊断及鉴别诊断的价值。方法收集３１０例肝脏占位性病变（包括原发性肝癌７２例，肝转移癌５８例，肝血管瘤３５例，肝脏肿２１例，肝包虫病５８例，肝囊肿６６例）的临床和ＣＴ资料，分析肝脏占位病变的部位、数目、边界以及增强后的ＣＴ表现。结果 肝脏占位性病变表现为单发或多发低密度灶，边界清或不清，增强后可有程度不一的强化或不强化。本组肝脏占位性病变各自均有典型的ＣＴ征象，大多能作出定性诊断。结论 ＣＴ对肝脏占位性病变的诊断及鉴别诊断有很大的价值。
Objective To investigate the value of CT in the diagnosis and differential diagnosis of liver space-occupying lesions. Methods The clinical data of 310 cases of hepatic lesions including 72 cases of primary liver cancer, 58 cases of hepatic metastases, 35 cases of hepatic hemangiomas, 21 cases of hepatomegaly, 58 cases of hepatic echinococcosis and 66 cases of hepatic cysts were collected CT data, analysis of the location of liver lesions, the number of border and enhanced CT performance. Results Liver lesions showed single or multiple low-density lesions, border clear or unclear, after the enhancement may have varying degrees of enhancement or not. This group of liver space occupying lesions have typical CT signs, most of them can make a qualitative diagnosis. Conclusion CT has great value in the diagnosis and differential diagnosis of liver space-occupying lesions.
