Application of hepatobiliary-specific MRI contrast agent Gd-EOB-DTPA in preoperative evaluation of hepatobiliary patients / 临床肝胆病杂志

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.
