肝脏灌注异常在肝脓肿诊断中的价值

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。

The Value of Abnormal Hepatic Perfusion in the Diagnosis of Hepatic Abscess

Objective To research the diagnostic value and the relative factors of abnormal hepatic perfusion in hepatic abscess. Methods During February 1998~ October 2003, spiral scan was perfomed in 34 patients with hepatic abscess, of which 34 patients with hepatocellular carcinoma without portal carcinomatous embolus were randomly selected. Following plain spiral CT scan of the liver, arterial phase scanning was started at 20 s after contrast injection. CT findings were observed and the relative factors of abnormal hepatic perfusion of hepatic abscess were analyzed. Results Abnormal hepatic perfusion in arterial phase was seen in 26 cases, of which 18 cases in hepatic abscess and 8 cases in hepatocellular carcinoma, presenting as irregular patchy high density. CT demonstrated that formation of abnormal hepatic perfusion was related to the course of diseases, but not related to the location of the lesions. Conclusion Abnormal hepatic perfusion is another important enhanced CT sign and is valuable in the diagnosis of hepatic abscess.
