摘要
目的:对比磁共振胰胆管成像和钆贝葡胺(Gadobenate Dimeglumine)增强胆道成像对肝胆管的显示能力。材料与方法:2006-03～2009-04解放军总医院行活体半肝移植的供体64例,术前在GESIGNA-EXCITE3.0T扫描仪上行冠状位厚层单击发快速自旋回波(2D-SSFSE)、3D快速自旋回波容积扫描(3D-FRFSE)及肝特异性造影剂钆贝葡胺增强胆管成像的肝脏快速三维容积采集序列(3D-LAVA)扫描,在GE4.3图像工作站行MIP后处理重建胆道系统,对比三种方法肝胆管显示能力并与术中所见对照。结果:三种成像方式显示胆总管、胆囊、肝总管、肝内一级胆管效果的差异无显著性意义(P>0.5)。3D-FRFSE对肝内三级以上胆管显示优于2D-SSFSE和钆贝葡胺造影(P<0.05),而肝胆管钆贝葡胺造影在诊断肝胆管解剖变异方面优于2D-SSFSE和3D-FRFSE序列。结论:肝特异性造影剂钆贝葡胺可单独用于肝胆管成像,与常规磁共振胰胆管成像联合应用有利于提高胆道显示的满意度。
Purpose To compare the capability of contrast-enhanced MR cholangiography and MRCP in diaplaying hepatobiliary anatomy. Methods and Materials 61 cases of living donor half-liver transplantation during March 2006 to April 2009 in General Hospital of PLA were included. Two-dimensional thick-slab single shot fast spinecho imaging sequence （2D-SSFSE）, three-dimensional fast spin-echo imaging sequence（3D-FRFSE） and contrast-enhanced MR cholangiography（CE-MRC） were performed in all donors before surgery. 3D images were processed in GE 4. 3 workstation. The capabilities of three methods in evaluating hepatobiliary anatomy was assessed and compared with findings during surgery. Results There were no significant difference among three methods in evaluating bile common duct, gallbladder hepatic common duct and the first branches of intrahepatic bile duct（P〉0.5）. 3D-FRFSE was superior to 2D-SSFSE and CE-MRC in evaluating the intrahepatic bile duct before third branches （P〈0.05）, while CE-MRC was superior to 2D-SSFSE and 3D-add： in detecting the anatomical variation of hepatobiliary duct. Conclusions As a specific hepatic contrast medium, MultiHance could be used alone in hepatobiliary duct imaging. When combined with MRCP, it can increase the ability of displaying biliary tract system.
