Abstract
：Objective To compare thevalue of biphasicmulti-detector row helical computed tomogrpahy(MDCT),digital subtractionangiography(DSA)and lipiodol computed tomography(CT)in hypervascular hepatocellularcarcinoma(HCC).Methods 80 cases with liver cancer were underwent MDCT、DSA、iodizedoil CT scan,then compared detection rates of three methods.Results In detecting hepaticnodules(＞2cm),these three imaging techniques had the same sensitivity;for 1～2cmhepatic nodules,the detecting rate had no significant difference;The MDCT scan＜1cmdetected 47 nodules(94.0%),iodized oil CT detected 27 nodules(54.0%),both statisticallysignificant difference in detection rate(χ~2=3.11,P＜0.01),DSAis only detected 16 nodules(32.0%)compared with enhanced dual-phase MDCT scan and iodizedoil CT detection rate the differences were statistically significant(χ~2=9.09,9.03,allP＜0.01).ConclusionMDCT is able to better show feeding arteries of hepatocellular carcinoma,The imagingexamination of liver cancer before treatment can be used as a comprehensive evaluation. Key words: Liver neoplasms; Tomography,X-ray computed; Digitalsubtraction angiography; Iodized oil
