目的 研究肝脓肿的ＣＴ 增强表现。方法 回顾分析了５２ 例手术或临床证实的肝脓肿病例的ＣＴ 平扫和增强扫描资料。结果 增强扫描表现为：①极早期，脓肿周围肝组织一过性明显强化；②早期，增强形式依肝脓肿结构不同而异，可为脓肿壁环状强化，或脓肿不规则强化；③延时，脓肿周围低密度水肿环可强化为等密度，或脓肿内部强化，病变范围缩小，液化坏死区更显明显。结论 ＣＴ平扫及增强扫描应作为肝脓肿的常规检查方法。
Objective To study CT enhancement of liver abscess. Methods A retrospective analysis of 52 cases of surgically or clinically confirmed cases of liver abscess CT scan and enhanced scan data. Results Enhanced scanning showed: ① extremely early, abscess around the transient enhancement of liver tissue; ② early, enhanced form of liver abscess varies according to the structure, for abscess ring enhancement, or abscess irregular enhancement; ③ delay , Low density edema around the abscess ring can be enhanced to equal density, or abscess internal strengthening, lesion narrowing, liquefaction necrosis area more obvious. Conclusion CT scan and enhanced scan should be routine examination of liver abscess.
