不典型肝脓肿的16层CT诊断

摘要

目的:探讨不典型肝脓肿的16层螺旋CT表现及其诊断价值.方法:经病理或临床证实21例不典型肝脓肿病人纳入研究,男15例,女6例,年龄35～81岁,平均60岁,采用16层螺旋CT增强三期扫描,层厚5mm.结果:不典型肝脓肿16层CT平扫表现多样,缺乏特点,多期增强有较特征表现.结论:不典型肝脓肿的多期增强CT扫描较有特征,有助于定性诊断.%Purpose: To assess the 16 - slice CT features of atypical hepatic abscesses and their diagnostic value. Methods: Twenty - one patients(male 15, female 6, age ranged from 35 to 81 years, mean age 60 years) with atypical hepatic abscesses which were confirmed at pathology or clinics were enrolled in this study. The precontrast and three - phase contrasted scan were undertaken with a 16 - slice CT scanher. Results: The CT findings of the atypical hepatic abscesses on precontrast scans were varied and were not specific, but that on contrasted scans had characteristics. Conclusion: The CT findings of atypical hepatic abscesses on multiphase enhanced CT scans were more specific, which were helpful to a correct diagnosis.
