Abstract:
Objective To determine the value of liver analysis application in liver segmentation and planning of surgery.Methods Thirty patients suspected having hepatic disease were recruited in this study.Contrast-enhanced CT examinations were performed with Philips Brilliance 64-slice CT,and multi-phase images were obtained.The patients were divided into group B(with focal hepatic lesion,15 patients),and group A(without hepatic lesion,15 patients).We use the portal-venous(60-70 s)images to analysis.Liver volume and vessel recognition were edited manually if necessary,then liver segmentation proceeded automatically.All data were analyzed by the t test,chi-square test,Mann-Whitney U analysis,with SPSS 15.0 software.Results There was no significant difference of post-processing procedure between the two groups(P =0.361).The liver volume was(1374.61 ±444.05)cm3 in the group B and(1225.70±272.07)cm3 in the group A(P=0.108).The accuracy of vessel recognition was no significant difference between the two groups(P=0.87).21 vessels were recognized incorrectly include 18 hepatic veins.Conclusion The liver analysis application provides a 3D reconstruction allow vivid observation of liver segmentation and accurate estimation of the liver volume.It has broad prospect in diagnosing and surgical planning of the liver disease.
