肝转移瘤的CT诊断

CT analysis of hepatic metastases

目的探讨肝转移瘤的CT表现,评价其CT临床应用价值。方法回顾性分析38例共134个肝转移瘤的CT表现及临床资料。结果肝转移瘤CT表现为多发病灶,少数为单发,呈圆形或类圆形低密度结节,少数为等密度,边缘模糊或清楚。强化多样,以边缘环形强化为主要特征,门脉期病灶显示更清楚。结论 CT增强扫描可提高肝转移瘤的检出率,有利于肝转移瘤特征的显示,密切结合临床资料不难诊断。

Objective To describe the manifestations of the hepatic metastases and to investigate the value of CT examination in diagnosis of hepatic metastases. Methods The three phase scanning of CT was performed in 38 patients with 134 lesions of liver metastasis. Results The CT imaging of hepatic metastasis showed mostly multiple lesions, which appeared as round or round-like low density with clear. The enhancement patterns were variable and charaeterized mainly of circle enhancing with interior low density. The lesion was demonstrated more clearly and easily detected in portal phase. Conclusions The three-phase scanning of CT can improve the detection of hepatic metastasis, which is helpful for the characterization of hepatic metastasis, helpful for differential diagnosis.
