摘　　要：[目的]在原发性肝癌病例中应用Phillip 256 i CT机全肝CT灌注扫描模式,探讨其一站式扫描的可行性。[方法]对临床诊断为原发性肝癌的33例病例进行全肝CT灌注扫描及延迟扫描,获得多时相动态增强扫描图像,采用容积再现(VR)、多层面重建(MPR)、最大密度投影(MIP)等血管重建方法及肝脏灌注后处理软件。[结果]所有病例均获取良好的多时相动态增强扫描图像,通过后处理可获得全肝灌注图像及肝动脉CTA、门静脉CTPA图像。其中所有病例上全肝灌注图像可以观察到瘤灶动脉供血增多、门脉血供减少;肝动脉CTA发现肿瘤血管20例、动脉扭曲移位14例、肝外动脉供血3例;门静脉CTPA上观察到门脉癌栓4例。[结论]256多层CT一站式扫描可以评估原发性肝癌血管的形态及动态血流信息,全肝CT灌注成像可以量化评估肝内病灶血流灌注情况,实现肝脏一站式扫描,对肝癌的诊断及临床治疗有重要意义。[Purpose] To investigate the application of Phillip 256 iCT total liver CT perfusion scanning mode in primary hepatoeellular carcinoma, and to explore the feasibility of a one-stop scanning.[Methods] For the clinical diagnosis of the hepatic CT perfusion scan and delayed scan of primary liver cancer in 33 cases, the muhiphase dynamic enhanced images, by volume rendering （VR）,multiplanar reconstruction （MPR）, maximum intensity projection （MIP） and other methods of vascular reconstruction and liver perfusion software were applied. [Results] All cases were ob- tained good multiphase dynamic enhanced scan,the after treatment can obtain whole liver perfu- sion image and hepatic artery, portal vein CTPA image CTA. In all cases on the whole liver peffu- sion image can be observed in the tumor artery,increased portal blood supply decrease ;hepatic artery CTA was found in 20 cases,tumor artery twist displacement in 14 cases,hepatic artery in 3 cases. Portal vein CTPA observed on portal vein tumor thrombus in 4 cases. [Conclusions] 256 layers of one-stop CT scan can evaluate information form and dynamic flow of hepatocellular car- cinoma, hepatic CT perfusion imaging can quantitative assessment of hepatic lesions perfusion. One-stop liver scanning has important significance for the diagnosis and treatment of hepatocellu- lar carcinoma.
