The diagnostic performance of MRI in the detection of HCCs of all sizes increases with the utilization of hepatobiliary contrast agents 1 The characterization of focal liver lesions is very important.

Thus, in the hepatobiliary phase, most adenomas are hypointense in relation to the surrounding parenchyma Figure 3. The utilization of such contrast agents increases the index of detection of hypo- and hypervascular metastases Figure 7.

Patients with advanced liver and kidney diseases alternatively compensate the hepatoxarcinoma agents clearance by renal or biliary excretion, respectively. Hemangiomas generally present typical imaging findings and are easily diagnosed by computed tomography or MRI with extracellular gadolinium contrast agent.


Diagnostic challenges and pitfalls in MR imaging with hepatocyte-specific contrast agents. Outcome of patients with fibrolamellar hepatocellular carcinoma.

As gadoxetic acid is utilized, the hepatobiliary phase occurs in 20 minutes, so it is recommended that the order of sequences acquisition be changed in order to optimize the acquisition time. No hepatobiliary contrast uptake is observed.

However, the differentiation between FNH and adenoma is not always easy at conventional MRI, because both conditions may hepatocarcinlma as nonspecific hypervascular lesions, generating anguish for the patient and challenging the physician, in addition to the cost and patient’s anxiety with repeated examinations. Journal of clinical oncology: Finally, the hepatobiliary phase is acquired 20 minutes after gadoxetic acid administration 1dkferencial.

Fibrolamellar hepatocellular carcinoma: a case report

Homogeneous hepatobiliary contrast uptake indicates the diagnosis of FNH. Eur J Cancer ; 49 However, MRI does not allow for the diagnosis in all cases whose etiology remains undetermined. The use of hepatobiliary contrast agents increases the diagnostic accuracy of magnetic resonance imaging and reduces the number of non-specific liver lesions.

Focal hepatic lesions, Hepatobiliary contrast, Magnetic resonance imaging.

Reporte de un caso. Hepatology ; 39 3: Radiology ; 1: Review of the clinicopathologic features of fibrolamellar carcinoma. Metastases do not contain functioning hepatocytes or biliary ducts, and do not show contrast uptake during the hepatobiliary phase. In cirrhosis, hepatocytes are progressively replaced by fibrotic tissue, so that the more advanced the fibrosis, the smaller the hepatic parenchyma enhancement in the hepatobiliary phase.


A fraction of hepatobiliary contrast agent is excreted by cMOAT into the biliary canaliculi multispecific canalicular organic anion transporter 1.

Diagnostic accuracy of MRI in differentiating hepatocellular adenoma from focal nodular hyperplasia: The doses recommended for intravenous injection of such contrast agents are also different, corresponding to 0. Female, year-old, asymptomatic patient presenting with a hypervascular liver nodule to be clarified, without intralesional fat and without central scar. Further potential hepatobiliary contrast applications include the evaluation of the functional hepatic reserve before partial hepatectomy; evaluation of live donor’s hepatic function as well as evaluation of early liver failure after transplant 4.
