摘要
背景:肝移植后胆管和血管方面的并发症是肝移植失败的主要原因,磁共振胆道成像常用来诊断胆道并发症。目的:对比钆贝葡胺增强胆道成像和磁共振胆道水成像对肝移植后胆管并发症的诊断价值。方法:80例肝移植后患者,均行钆贝葡胺增强后胆道成像和磁共振胆道水成像,对比其对肝移植后胆道显示及胆道并发症的诊断价值,所有诊断均经临床证实。结果与结论:80例患者,胆道水成像71例胆道显示良好,增强胆道成像59例胆道显示良好,差异有显著性意义(P<0.05),胆道显示水成像优于增强胆道成像。胆道狭窄34例,胆道水成像准确诊断23例,增强胆道成像准确诊断30例,差异有显著性意义(P<0.05),胆道狭窄诊断增强胆道成像优于水成像。提示磁共振胆道水成像和钆贝葡胺增强胆道成像诊断活体肝移植后并发症各有优缺点,联合应用效果更佳。
BACKGROUND： Biliary and vascular complications are the main reason of failed liver transplantation. Magnetic resonance cholangiography is often used to diagnose biliary complications. OBJECTIVE： To compare gadobenate dimeglumine-enhanced T1-weighted magnetic resonance cholangiography （CE-MRC） with conventional T2-weighted magnetic resonance cholangiography （T2WI-MRC） for evaluation of biliary complications after liver transplantation. METHODS： 80 patients who received liver transplantation were examined with two magnetic resoance cholangiographic methods. The diagnosis value for biliary complications was compared between these two methods. All diagnoses were clinically confirmed. RESULTS AND CONCLUSION： Among 80 patients, 71 patients acquired good image quality in T2WI-MRC and 59 acquired good image quality in CE-MRC, and there was significant difference （P 0.05）, indicating that T2WI-MRC is better than CE-MRC in biliary observation after liver transplantation. Among 34 patients presenting with biliary stricture, 23 patients were accurately diagnosed by T2WI-MRC and 30 patients were accurately diagnosed by CE-MRC, and there was significant difference （P 0.05）, indicating that CE-MRC is superior to T2WI-MRC in diagnosis of biliary stricture. Both T2WI-MRC and CE-MRC can evaluate biliary complications of liver transplantation. They have advantages and disadvantages separately and they produce better application effects after united application than single alone.
