Objective To investigate the diagnostic value of a double action MR contrast agent——gadobenate dimeglumine （Gd-BOPTA） for focal liver lesion and biliary system disease. Methods Articles about Gd-BOPTA in CNKI and PubMed for the past few years were searched and the value of Gd-BOPTA in the diagnosis of focal liver lesion and biliary system disease was summarized. Results For focal liver lesion, Gd-BOPTA not only can reveal blood supply of the lesion, but also reveal the hepatocellular functional status in the lesion. For biliary system, biliary excretion of Gd-BOPTA can be used to evaluate the anatomic structure of bile duct， function of gallbladder and biliary system disease. Conclusions Gd-BOPTA has an important value in the diagnosis of focal liver lesion and biliary system disease. Gd-BOPTA may have wider applications in the future.
ObjectiveTo summarize the application of dual-energy CT scanning technology in the liver. MethodsTo search the relevant literatures at home and abroad, then the application of dual-energy CT scanning technology in focal liver lesions, diffuse liver lesions were analyzed and summarized. ResultsDual-energy CT scanning technology can improve detection rate of the focal liver lesions, liver cancer recurrence lesions after local treatment and help to differentiate focal liver lesions, to stage the malignant lesions, and it also can be more accurate quantification of liver iron, fat content, indirect measurement of hepatic blood flow dynamics change situation. ConclusionDual-energy CT scanning technology can improve the diagnostic value of CT scanning technology in liver disease.
