目的：探讨320排 CT 一站式成像定量分析技术在肝癌术前评估中的准确性及临床应用价值。方法对42例原发肿块型肝癌患者术前进行320排 CT 一站式成像,包括重组增强图像、灌注定量分析、肝体积定量评估和血管成像,术后对切除肝脏体积进行水测量法测量并对肝功能进行评价。结果42例肿块型肝癌组织灌注肝动脉血流量(AF)、门静脉血流量(PF)以及肝动脉灌注指数(HAPI)均值与正常肝组织存在显著差异,P 值均<0.05。术前评估预切除肝体积与术后水测量肝体积结果无差异,P 值>0.05。血管成像与外科术中评估符合率达95.2%(40/42例),对大血管及一、二级分支血管评估的准确率为100%。结论利用320排CT 定量分析技术能对活体肝组织灌注、血管构筑及肝脏体积作出准确术前评估。

Objective To investigate the preoperative evaluating accuracy of liver cancer using one-stop imaging quantification technique of 320 row CT and its clinical application value.Methods 42 patients with primary mass-forming liver cancers underwent one-stop imaging by 320 row CT,including enhancement imaging,perfusion quantification,liver volume quantification and angiogra-phy.After surgery,the volume of excised livers were measured.Liver function was also evaluated.Results After liver perfusion quantification,significant differences in hepatic artery flow,portal venous flow and hepatic artery perfusion index were found be-tween the 42 cases of mass-forming liver cancers and normal liver tissues (P <0.05).No significant difference was found between preoperative quantified liver volume and postoperative measured liver volume (P >0.05).The diagnostic accuracy by CT angiogra-phy was up to 40/42 cases (95.2%)through surgical verification.The diagnostic accuracy of large blood vessels and the first or sec-ond level branches were 100%.Conclusion The quantitative analysis of one-stop imaging technique by 320 rows CT can accurately evaluate the liver perfusion,angio-architecture and liver volume before surgery.
