肝脓肿的CT诊断

The Value of CT Diagnosis in the Hepatic Abscess

目的:探讨肝脓肿的CT征象,提高肝脓肿的诊断正确率。方法:回顾性研究经手术或临床证实的细菌性肝脓肿病例21例,治疗前行CT平扫和动态增强扫描,分析其CT表现。结果:CT平扫表现肝内低密度灶占20例(20/21,95.2%);病灶内气-液平面3例(3/21,14.3%);动态强化扫描表现:分隔状强化8例(8/21,38.1%);双靶征9例(9/21,42.9%);边缘强化征11例(11/21,52.4%)。结论:CT扫描特别是动态CT增强扫描征象对肝脓肿的诊断有较高价值。

Objective To evaluate CT features of hepatic abscess and its pathologic basis. Methods The CT features of 21 bacterial hepatic abscesses proved by surgery or clinic were retrospectively studied. Results CT manifestations of hepatic abscess included signs of low density area（20/21,95.2% ）, the level of gas and liquid （3/21,14.3%）, a piece of enhancement without any signs in no contrast CT （ 1/21,0.05% ） ,septa enhancement （8/21,38.1%） ,double targets （9/21,42.9%） ,peripheral enhancement （11/21,52.4%）. Conclusion CT,especially dynastic contrast CT,was helpful in the diagnosis of hepatic abscess.
