目的探讨肝硬化的多层螺旋CT灌注成像表现。方法对25例肝硬化患者及12例健康成人作为对照者行肝脏16层螺旋CT灌注成像,得到肝脏血流灌注参数值,并与Child分级相对照。结果与正常对照组比较,随着肝硬化程度的加重,肝脏的血流量(BF)、血容量(BV)逐渐降低,肝动脉分数(HAF)逐渐增高;平均通过时间(MTT)未见明确变化规律。结论CT灌注成像有助于早期诊断肝硬化,而且可以用于评价肝硬化病变程度,具有一定的临床意义。
Objective To investigate the multi-slice spiral CT perfusion imaging of liver cirrhosis. Methods Twenty-five patients with cirrhosis and 12 healthy adults were enrolled in this study. Sixteen-slice spiral CT perfusion imaging of the liver was performed. The parameters of hepatic perfusion were obtained and compared with Child classification. Results Compared with the normal control group, the liver blood flow (BF), blood volume (BV) and hepatic artery fraction (HAF) increased gradually with the degree of liver cirrhosis increasing. The mean transit time (MTT) law. Conclusion CT perfusion imaging is helpful for the early diagnosis of cirrhosis, and can be used to evaluate the degree of cirrhosis. It has certain clinical significance.
