The pharmacokinetics and doses of gadobenate dimeglumine and gadoxetic acid are different. The main indications for the method include: Also, hepatobiliary contrast-enhanced cholangiography allows for the accurate detection of postoperative complications such as biliary fistulas and bilomas which present progressive fill-in during the hepatobiliary phase.
High-degree dysplastic nodules lose the portal vascularization and start gaining abnormal arterial vascularization. Vilgrain V, Vullierme MP. Chun YS, Zimmitti G.
GCR ; 6 1: Well-differentiated HCCs contain functioning hepatocytes and might show hepatobiliary contrast uptake. European journal of surgical oncology: Additionally, hepatobiliary contrast agents allow for evaluating the biliary tract 1 – 3.
However, MRI does not allow difdrencial the diagnosis in all cases whose etiology remains undetermined. The metastatic implants that do not contain hepatocytes become hypointense.
The previous knowledge of the biliary anatomy and its variations becomes increasingly important in the preoperative planning, considering the complexity of the hepatic anatomy as well as of the more helatocarcinoma surgical techniques, which reduces the occurrence of postoperative complications 4. Note the capacity of hepatobiliary contrast to detect very small lesions which cannot be visualized on the other sequences.
Primary hepatic malignant neoplasms.

Initially, the T1-weigthed sequences in-phase, out-ofphase and with fat saturation are performed. Hepatobiliary contrast uptake by HCCs depends on the tumor differentiation stage and on the amount of functioning hepatocytes 24.
Small nodules are observed adjacent to the gallbladder, with hyposignal on T2-weighted sequence, without expression on the other sequences and on the conventional dynamic study, but with hepatobiliary contrast uptake, leading to the diagnosis of regenerative nodules.
Phase II trial of systemic continuous fluorouracil and subcutaneous recombinant interferon Alfa-2b for treatment of hepatocellular carcinoma. As necessary, heavily T2-weighted cholangiographic images should also be acquired before the contrast injection, since hepatobiliary contrast agents are excreted by the biliary tract and can shorten the T2-relaxation time.

Fibrolamellar hepatocellular carcinoma: a case report
Benign liver lesions are frequently found, even in patients with known neoplasia. Considering that the presence of intralesional fat in NFH is rare, the patient will be maintained under imaging follow-up.
Docente Universidad de Antioquia. Female, year-old, asymptomatic patient presenting with a hypervascular liver nodule to be clarified, without intralesional fat and without central scar. The diagnosis of sphincter of Oddi dysfunction can be based on the finding of absent or delayed passage of the hepatobiliary contrast thru the ampulla of Vater. Clinical value of MRI liver-specific contrast agents: The conclusions reinforce the importance of radiological imaging for the detection and characterization of hepatic focal neoplasms.
Review of the clinicopathologic features of fibrolamellar carcinoma. Female, year-old patient presenting with colon cancer. Hepatobiliary contrast allows for the differentiation between biliary lesions and extrabiliary cysts, since it delineates the biliary tract, demonstrating the communication of biliary cystic lesions with the bile ducts, and extrabiliary cystic lesions that do not communicate with bile ducts, such as pseudocysts, duodenal diverticula and duodenal duplication cysts 5.
AMA journal of diseases of children ; 91 2: Fibrolamellar variant of hepatocellular carcinoma does not have a better survival than conventional hepatocellular carcinoma–results and treatment recommendations from the Childhood Liver Tumour Strategy Group SIOPEL experience.
In summary, hepatobiliary contrast increases the MRI accuracy and reduces the number of cases of undefined liver lesions. Diagnostic Histopathology ; 16 8: Hepatobiliary contrast increases the method’s sensitivity to detect liver metastasis, particularly the small-sized ones. Hemangiomas normally have a typical presentation at MRI with extracellular contrast and are not an indication for investigation with hepatobiliary contrast. Distinguishing hypervascular pseudolesions of the liver from hypervascular hepatocellular carcinomas with gadoxetic acid-enhanced MR imaging.
