摘要: 目的 评价肝脏分析软件(liver analysis application)在肝脏分段及术前评估方面的临床应用价值.方法 对30例怀疑肝脏疾病的患者进行腹部肝脏增强CT检查.患者分为肝内占位性病变组(实验组B)和无肝内占位组(对照组A),每组各15例.利用肝脏分析软件对所有患者的门脉期原始数据进行重建分析.测量肝脏及肝内病变体积,并根据血管走行及分布对肝脏进行自动分段.使用SPSS 15.0软件、t检验、x2检验和非参数Mann-Whitney U法分析检测数据.结果 软件后处理过程两组差异无统计学意义(P=0.361);实验组肝脏体积为(1374.61±444.05)cm3,对照组肝脏体积为(1225.70±272.07)cm3(P=0.108).血管识别准确率实验组Ⅰ级为7例(46.7%),Ⅱ级为5例(33.3%),Ⅲ级为3例(20%);对照组Ⅰ级为7例(46.7%),Ⅱ级为6例(40%),Ⅲ级为2例(13.3%)(P=0.87),两组血管识别率差异无统计学意义.两组共有21段血管识别错误,其中18段为肝静脉,占85.71%(18/21).结论 64排螺旋CT肝脏分析软件可以直观显示肝脏病变、血管及肝段解剖,并进行定量分析,对肝脏病变术前评估、手术方案制定有很大意义. 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.
