Radiology ; 2: On the other hand, the enhancement in the hepatobiliary phase is prolonged, allowing for acquisition of images with better spatial resolution, as well as its repetition in case of imaging artifacts 4.

Subsequently, gadoxetic acid is intravenously injected and the dynamic study arterial, portal and delayed phases is performed. In the postoperative follow-up, inadvertent ductal ligation can also be easily recognized in the hepatobiliary phase as an abrupt interruption of the biliary diagnodtico 45.

Male, year-old patient presenting with chronic C virus hepatopathy. Diagnostic challenges and pitfalls in MR imaging with hepatocyte-specific contrast agents. Clinicopathologic features and survival in fibrolamellar carcinoma: Arterial embolization in the treatment of hemobilia after hepatic trauma: The American journal hepatocrcinoma gastroenterology ; Find articles by Daniella Braz Parente. 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 hspatocarcinoma24.

Hypovascular metastases with diffusion restriction. Low-grade regenerative and dysplastic nodules present preferentially portal vascularization, contain functioning hepatocytes and, like the surrounding parenchyma, show hepatobiliary contrast uptake. Received Jul 23; Accepted Oct Focal liver lesions enhancement may be less intense during the dynamic study, particularly in the arterial phase, because the recommended dose of gadoxetic acid is lower than the habitual extracellular gadolinium dose 5.

Consequently, the hepatobiliary phase acquisition time is different for each type of contrast agent and should be obtained minutes after gadobenate dimeglumine administration ranging between 1 and 3 hoursand 20 minutes after gadoxetic acid administration ranging between 10 and minutes 1.

Primary hepatic malignant neoplasms. 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.

The differentiation between HCC and perfusion alterations may also represent a diagnostic challenge.

The main indications for the method include: Female, year-old patient presenting with colon cancer. Well-differentiated HCCs contain functioning hepatocytes and might show hepatobiliary contrast uptake. 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.

Cancer ; 97 8: Male, year-old patient presenting with colon cancer and multiple metastases, with hyposignal on T1-weighted, and subtle hypersignal on T2-weighted sequence.

Several studies diagnostic evaluating the relation between the degree of hepatic fibrosis in diagnodtico with cirrhosis As well as the hepatobiliary contrast enhancement with the objective of reducing the necessity of biopsies currently considered a gold standard. Male, year-old patients presenting with chronic hepatopathy and liver nodule to be clarified, adjacent to the gallbladder, as seen at ultrasonography.

Additionally, as compared with healthy livers, cirrhotic livers present later enhancement peak and slower washout 32 – Eur J Cancer ; 49 Journal List Radiol Bras v.

On the other hand, poorly-differentiated or undifferentiated hepatocarcinomas do not contain functioning hepatocytes and do not show hepatobiliary contrast uptake, remaining hypointense in relation to the surrounding parenchyma 21017 – 19 Figure 6. Journal of hepatology ; 56 4: Caroli’s disease complicated with liver abscess: Magnetic resonance imaging is considered the best imaging method for evaluating such lesions, but does not allow for the diagnosis in all cases.

Journal of clinical oncology: Hepatobiliary-specific MR contrast agents: Liver abscesses secondary to acute cholangitis. As gadobenate dimeglumine is utilized, it is recommended that the MRI study be performed as usual, including the dynamic study up to the delayed phase; then the procedure be interrupted and the patient returns after minutes for acquisition of the hepatobiliary phase. Outcome of patients with fibrolamellar hepatocellular carcinoma.

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. Fibrolamellar variant of hepatocellular carcinoma does not have a better survival hepatocaecinoma conventional hepatocellular carcinoma–results and treatment recommendations from the Childhood Liver Tumour Strategy Group SIOPEL experience.

FNH presents greater density of functioning hepatocytes than a healthy liver parenchyma, in association with abnormal bile ducts which do not communicate with greater bile ducts, with consequential slower biliary excretion as compared with the surrounding liver.

The smallest lesion arrowheads presents subtle hypersignal on T2-weighted and marked signal loss on out-of-phase T1-weighted difegencial caused by the presence of intralesional fat.

Cancer ; Hepatology ; 49 3: Perfusional alterations present a signal similar to the one of the remainder hepatic tissue during the portal and hepatobiliary phases, while most HCCs, except the well-differentiated ones, present hyposignal in the hepatobiliary phase
