Title: Application of multi-slice CT angiography in the diagnosis of extrahepatic hepatocellular carcinoma
Abstract: Objective:To evaluate the diagnostic value of MSCTA for extrahepatic hepatocellular carcinoma(EHCC).Methods:23 patients of EHCC with surgical and pathological confirmation were analyzed retrospectively.Their MSCT angiographies with volume rendering arterial reformation(add vessel)technique could delineate the feeding artery of tumors and then the correlative study was taken with surgical results for determination of accurcy for tumor localization and vicinity invasion.Results:25 tumors 23 patients,included 2 with pediculas and the other 23 with basal attachment to the liver;and the maximum diameter was 6.5~17.5cm(mean 10.8cm).Feeding artery originated from the branch of right hepatic artery(RHA)supplied the tumors in the right or/and caudate lobe of liver;wheras the tumors in the left lobe were fed by left hepatic artery(LHA).The localization sensitivity with MSCTA reached 100%(25/25).Five tumor invasions of the adjacent organs were demmstrated in 4 cases,but only 3 collateral feeding arteries were shown on MSCTA.Conclusion:MSCTA can make accurate localization for EHCC due to opacification of the tumor feeding artery,and furthermore provide rather high value in diagnosing invasion to the adjacent organs.
