摘　　要：目的:探讨CT灌注成像在肝脏结节性病变鉴别诊断中的应用价值。方法:采用16层螺旋CT对肝细胞癌(hepa-tocellular carcinomas,HCC)25例、肝转移瘤(hepatic metastastes,HM)19例和肝血管瘤(hemoangiomas,HA)6例进行灌注扫描,分别计算其肝动脉灌注量(hepatic arterial perfusion,HAP)、肝门静脉灌注量(hepatic portal perfusion,HPP)、总肝灌注量(totalliver perfusion,TLP)和肝动脉灌注指数(hepatic arterial perfusion index,HAPI),并进行对比分析。结果:HCC、HM和HA组各CT灌注参数具有显著性差异。结论:CT灌注成像在肝结节性病变的鉴别诊断中具有重要的应用价值。Objective：To study the differential value of muhidetector computed tomography （MDCT） perfusion imaging in liver nod- ules. Methods： MDCT perfusion imaging was performed in 25 patients with hepatoeellular carcinomas （HCC） , 19 patients with hepatic metastastes （HM）, and six patients with hemoangiomas （HA）. The CT perfusion parameters, such as hepatic arterial perfusion （HAP） ,hepatic portal perfusion （HPP） ,total liver pcrfusion （ TLP）, and hepatic arterial perfusion index （HAPI） ,were calculated with the slope method. Results： The values of CT perfusion parameters were significantly different among the three groups. Conclu- sion： The changes of CT perfusion imaging parameters of HCC,HM and HA are of great values in the differential diagnosis.
