Application of quantitative analysis in the preoperative evaluation of liver cancer with 320 row CT / 实用放射学杂志

ABSTRACT

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).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.
