Axial T1-weighted Sequence Obtained after Intravenous Injection of EovistAxial T1-weighted sequence obtained 20 minutes after intravenous injection of the hepatobiliary imaging agent Eovist (gadoxetate disodium). There was variable Eovist uptake in the liver lesions seen on T2-weighted imaging. In this centrally-located lesion (indicated by arrow), there is poor Eovist uptake compared with background liver parenchyma. Functional hepatocytes are required for Eovist uptake, and FNH typically contains functional hepatocytes; therefore, poor Eovist uptake is concerning for a non-hepatocyte-containing neoplasm. In this patient, this imaging expectation led to a false positive result. FNH - focal nodular hyperplasia.
