【摘要】:钆塞酸二钠(Gd-EOB-DTPA)是一种新型肝细胞特异性对比剂,经胆道和肾脏双通道排泄,具有非特异性细胞外对比剂和肝细胞特异性对比剂的双重特点,将动态期成像和肝胆特异期成像的特点结合可清晰地显示肝脏局灶性病变,可以在相对短的时间内对肝脏血流灌注、胆管成像、定性和检测肝脏局灶性病变、评估肝功能。国内外大量研究已证实肝胆特异性磁共振检查在肝癌尤其是小肝癌的定性诊断中明显优于磁共振成像、增强CT及超声检查。介绍了该对比剂的特点、在肝胆手术术前评估中的应用现状及展望。
【Abstract】:Gd-EOB-DTPA, a newly applicable hepatocyte-specific contrast agent, is excreted through the biliary tract and the kidney, showing the characteristics of nonspecific extracellular contrast agent and hepatocyte-specific contrast agent. It can provide both dynamic and hepatobiliary images and has been rapidly accepted by clinicians for the diagnosis of liver lesions and preoperative evaluation. Gd-EOB-DTPA can fulfill hepatic perfusion imaging, cholangiography, detection and characterization of focal liver lesions, and evaluation of liver function within the same examination in a relatively short time window. A large number of domestic and foreign studies have confirmed that hepatobiliary-specific contrast-enhanced MRI is significantly superior to MRI scan, contrast-enhanced CT, and ultrasound in diagnosing hepatocellular carcinoma, especially small hepatocellular carcinoma. The features of Gd-EOB-DTPA and its current status and prospect of application in the preoperative evaluation of hepatocellular carcinoma are reviewed in this article.
