Cancer ; The currently available hepatocyte-selective contrast media are the following: Adenomas are well defined, homogeneous or heterogeneous lesions.
Adverse effects of hepatobiliary contrast agents rarely occur and, if present, are similar to the ones reported in the use of extra-cellular gadolinium. The most frequent differential diagnoses for hypervascular lesions in patients with no hepatopathy include hemangioma, FNH and adenoma. Additionally, as compared with healthy livers, cirrhotic diferencal present later enhancement peak and slower washout 32 – Radiology ; 2: Female, year-old, asymptomatic patient presenting diiagnostico a hypervascular liver nodule to be clarified, without intralesional fat and without central scar.
Fibrolamellar hepatocellular carcinoma: a case report
Like in cirrhosis, perfusional alterations in patients with metastasis show contrast uptake in the hepatobiliary phase, differently from metastases 1. Hepatology ; 39 3: In the hepatobiliary-phase, the liver parenchyma shows contrast uptake and becomes hyperintense.
The different enhancement patterns depend on the histological grade of the HCCs and may be explained by the membrane transporters expression. Belo Horizonte, MG, The doses recommended for intravenous injection of such contrast agents are also different, corresponding to 0. European journal of surgical oncology: Radiology ; 3: Poorly differentiated or undifferentiated HCCs do not contain functioning hepatocytes so hepatobiliary contrast uptake is not observed. GCR ; 6 1: Case reports in oncology ; 5 1: The conclusions reinforce the importance of radiological imaging for the detection and characterization of hepatic focal neoplasms.
Case Report of Fibrolamellar Hepatocarcinoma, a Rare Tumor of Young Adults
The largest lesion arrows presents high signal intensity on T2-weighted, hyposignal on t1-weighted sequence, and nodular, peripheral and discontinuous hepatoxarcinoma in the arterial-phase, and no hepatobiliary contrast uptake that is a typical hemangioma behavior. Phase II trial of systemic continuous fluorouracil and subcutaneous recombinant interferon Alfa-2b for treatment of hepatocellular carcinoma.
Hepatobiliary contrast uptake by HCCs depends on the tumor differentiation stage and on the amount of functioning hepatocytes 24. Cancer ; 6: Hepatobiliary contrast increases the method’s sensitivity to detect liver metastasis, particularly the small-sized ones. The utilization of such contrast heepatocarcinoma increases the index of detection of hypo- and hypervascular metastases Figure 7.
Thus, the lesions enhancement in the hepatobiliary phase depends upon the expression and activity of such transporters, determining characteristic enhancement patterns depending on the presence or absence of functioning hepatocytes. MR Imaging of hepatocellular carcinoma in the cirrhotic liver: As a result, the healthy hepatic tissue remains hyperintense and the metastasis, hypointense, which facilitates its detection 12.

However, considering that hemangiomas are common lesions, they will be frequently present on images acquired with hepatobiliary contrast for several reasons.
On the other hand, the lesions showed homogeneous hepatobiliary contrast uptake, hence the highest likelihood of the diagnosis of multiple FNHs. Such contrast agents shortens the T1 relaxation time of the bile and allows for the performance of a high-resolution T1-weighted cholangiography 4.
