Fibrolamellar hepatocellular carcinoma in children and adolescents. Journal of clinical oncology: The characterization of focal liver lesions is very important.
Imaging of fibrolamellar hepatocellular carcinoma. Radiol Clin North Am ; The typical FNH presents with septa and lobulated or microlobulated borders, with intermediate signal intensity on T1- and T2-weighted sequences, low lesion-organ contrast and homogeneous arterial contrast uptake, with decay in the subsequent phases, becoming isointense to the adjacent liver parenchyma.
Fibrolamellar hepatocellular carcinoma: a case report
Further potential hepatobiliary contrast applications include evaluation of ehpatocarcinoma functional hepatic reserve before partial hepatectomy; evaluation of live donor’s hepatic function as well as evaluation of early liver failure after transplant. J Korean Soc Radiol.
Poorly differentiated or undifferentiated HCCs do not contain functioning hepatocytes so hepatobiliary contrast uptake is not observed. In summary, hepatobiliary contrast increases the MRI accuracy diagnoztico reduces the number of cases of undefined liver lesions.
Well-differentiated HCCs diagnostic hepatobiliary contrast uptake, requiring imaging follow-up. Thus, in the hepatobiliary phase, most adenomas are hypointense in relation to the surrounding parenchyma Figure 3. Hepatobiliary contrast uptake by HCCs depends on the tumor differentiation stage and on the amount of functioning hepatocytes 24.
Hemangiomas present the same imaging findings at dynamic studies with hepatobiliary contrast; however, in the delayed phase, as the hepatobiliary contrast medium is leaving the interstitium and entering into the functioning hepatocytes, the hemangioma fill-in might or might not occur in this phase, differing from its usual behavior with the use of extracellular gadolinium Patients with cirrhosis Child A or B do not present any significant alteration in the total clearance of hepatobiliary contrast agents; but in cirrhosis Child C, there is a decreased total clearance and increased half life, with compensatory increase of renal excretion 8.
Hepatobiliary-specific MR contrast agents: Eur J Cancer ; 49 Radiology ; diferenciap Hepatobiliary contrast agents for contrast-enhanced MRI of the liver: Adenomas are composed of hepatocytes containing glycogen and lipids surrounded by a capsule.
Case Report of Fibrolamellar Hepatocarcinoma, a Rare Tumor of Young Adults
The diagnostic performance of MRI in the detection of HCCs of all sizes increases with the utilization of hepatobiliary contrast agents 1 Cancer ; Unique phenotype of hepatocellular cancers with exon-3 mutations in beta-catenin gene. Hepatology ; 39 3: In the postoperative follow-up, inadvertent ductal ligation can also be easily recognized in the hepatobiliary phase as an abrupt interruption of the biliary tract 45.
Such contrast agents are absorbed by hepatocytes via OATP1 transporter polypeptide adenosintriphosphate-dependent organic anion transporterthe same as the bilirubin transporter.
The usual dynamic study with arterial, portal and delayed phases is also performed with such contrast agents. Effect of flip angle for optimization of image quality of gadoxetate disodium-enhanced biliary imaging at 1.
Clinicopathologic characteristics and survival outcomes of patients with fibrolamellar carcinoma: Imaging evaluation of congenital cystic lesions of the biliary tract. Distinguishing hypervascular pseudolesions of the liver from hypervascular hepatocellular carcinomas with gadoxetic acid-enhanced MR imaging.
Additionally, as compared with healthy livers, cirrhotic livers present later enhancement peak and slower washout 32 – How to cite this article. The imaging characterization of benign and malignant liver lesions is very important. Current problems in diagnostic radiology ; 36 6:
