Application of hepatic tumor specific magnetic resonance enhancement with Gd EOB DTPA in the preoperative evalua tion of hepatocellular carcinoma

Hepatic tumor-specific magnetic resonance (MR) enhancement with Gd-EOB-DTPA can detect and distinguish small hepatocellular carcinoma (HCC) with greater sensitivity than conventional magnetic resonance imaging and computed tomography.Hepatic tumor-specific MR enhancement with Gd-EOB-DTPA is more sensitive in detecting focal HCC,and more reliable in detecting lesions with a diameter smaller than 2cm.Gd-EOB-DTPA is excreted through the kidneys and biliary tract,and thus may provide more information about anatomic structures,demonstrate non-obstruction of the intra- and extrahepatic bile duct system,and provide information about hepatic function.
