Phase II trial of systemic continuous fluorouracil and subcutaneous recombinant interferon Alfa-2b for treatment of hepatocellular carcinoma. Adenomas are composed of hepatocytes containing glycogen and lipids surrounded by a capsule.
However, in cases of advanced cirrhosis, the contrast uptake by the liver parenchyma may be compromised by decreased hepatocytes function, which would result in reduction of the method’s accuracy to detect HCCs 4 How to cite this article. 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.
Services on Demand Article. Well-differentiated HCCs show hepatobiliary contrast uptake, requiring imaging follow-up. American journal of clinical pathology ; 4: Calcification in focal nodular hyperplasia: Hepatobiliary contrast uptake by HCC also depends on its differentiation stage.
Initially, the T1-weigthed sequences in-phase, out-ofphase and with fat saturation are performed. Contrast enhancement of liver lesions in cirrhotic patients: Support Center Support Center. Magnetic resonance imaging MRI with intravenous contrast injection extracellular gadolinium-based contras media commonly utilized in the radiological practice is considered the best imaging method in the evaluation of such lesions.

MR imaging of hypervascular lesions in the cirrhotic liver: The different enhancement patterns depend on the histological grade of the HCCs and may be explained by the membrane transporters expression. Considering that the presence of intralesional fat in NFH is rare, the patient will be maintained under imaging follow-up. Several studies are evaluating the relation between the degree of hepatic fibrosis in patients with cirrhosis As well as the hepatobiliary contrast enhancement with the objective of reducing the necessity of biopsies currently considered a gold standard.
Takano H, Smith WL.
Effect of flip angle for optimization of image quality of gadoxetate disodium-enhanced biliary imaging at 1. Open in a separate window. The metastatic hepatocarfinoma that do not contain hepatocytes become hypointense.
Fibrolamellar hepatocellular carcinoma: a case report
Reporte de un caso. Rarely, there is hepatobiliary contrast uptake by adenomas and, in cases where it occurs, such an uptake tends to be preferentially peripheral in the hepatobiliary phase 124.
Note the capacity of hepatobiliary contrast to detect very small lesions which cannot be visualized on the other sequences. 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 refined surgical techniques, which reduces the hepatocarcinma of postoperative complications 4.
Fibrolamellar carcinoma of the liver: Hepatobiliary-specific MR contrast agents: The conclusions reinforce the importance of radiological imaging for the detection and characterization of hepatic focal neoplasms.
The characterization of focal liver lesions is very important. FNH is a benign lesion that does not require any intervention, while adenoma presents risk for malignization, necrosis and bleeding which might require emergency surgery.

Current problems in diagnostic radiology ; 36 6: National Center for Biotechnology InformationU. On the other hand, the lesions showed homogeneous hepatobiliary contrast uptake, hence the highest likelihood of the diagnosis of multiple FNHs.
The main indications for the method include:
