Core Tip

Core Tip: The translational objective was to determine the value of hepatobiliary phases using gadoxetic acid as a liver-specific agent in magnetic resonance imaging (MRI) in the characterization of benign and malignant focal liver lesions (FLL) in clinical practice. Morphofunctional MRI with gadoxetic acid in addition to the usual dynamic phases after contrast medium (arterial, portal and transitional/ equilibrium) increased the proportion of hits for differentiation between benign and malignant FLL in relation to the definitive diagnosis. The results suggest a relevant impact on the definition of strategies for the approach of focal hepatic lesions, as well as in the assessment of the treatment employed.
