目的研究肝脏灌注异常在肝脓肿诊断中的价值,探讨肝灌注异常形成的相关因素。方法随机选择1998-02—2003-10肝脓肿病例共34例作为研究组,并随机选择同期不伴有门静脉癌栓的肝癌34例作为对照组。全肝平扫后,于开始注射对比剂后20s行全肝动脉期扫描。观察动脉期CT表现,并分析肝灌注异常形成的相关因素。结果动脉期扫描肝脏灌注异常共26例,其中肝脓肿18例,肝癌8例,均表现为不规则斑片状、楔形高密度区。肝灌注异常的形成与病灶的部位无关,而与病程有相关性。结论肝脏灌注异常是肝脓肿的又一重要的增强CT表现,在肝脓肿的诊断中有重要价值。
Objective To investigate the value of abnormal liver perfusion in the diagnosis of liver abscess and to explore the related factors of liver perfusion abnormality. Methods A total of 34 cases of liver abscess from 1998-02-2003-10 were randomly selected as the study group and randomly selected 34 cases of hepatocellular carcinoma without portal vein thrombosis in the same period as the control group. Whole liver plain scan, in the beginning after injection of contrast agent 20s line hepatic artery phase scan. The arterial phase CT findings were observed, and the related factors of hepatic perfusion abnormalities were analyzed. Results There were 26 cases of arterial phase anomalies in liver perfusion. Among them, 18 cases of liver abscess and 8 cases of liver cancer showed irregular patchy and wedge-shaped high-density areas. The formation of abnormal liver perfusion has nothing to do with the site of the lesion, and has a correlation with the course of the disease. Conclusions Abnormal liver perfusion is another important CT manifestation of hepatic abscess. It is of great value in the diagnosis of liver abscess.
