Imaging features and management of focal liver lesions

Figure 4 Focal nodular hyperplasia. A: Axial T2-weighted magnetic resonance imaging (MRI)shows a slightly hyperintense lesion (arrow); B: Axial T1-weighted MRI reveals a slightly hypointense lesion (arrow); C: Arterial phase T1-weighted MRI with a hepatobiliary-specific contrast agent shows homogenous enhancement of the lesion (arrows); D: Portal venous phase T1-weighted MRI indicates the lesion is isointense (arrow); E: Hepatobiliary phase T1-weighted MRI shows persistent peripheral enhancement of the lesion (arrow) with a hypointense central scar (arrowhead).
