Figure 5 Focal nodular hyperplasia-like nodule in a 45-year-old man with hepatitis B infection. A: Precontrast T1-weighted image shows isointensity of the tumor; B: Hepatic arterial phase using gadoxetic acid shows lobulating-contoured, marked enhanced nodule in segment 4; C, D: Portal venous and transitional phases show slight hyperenhancement of the tumor relative to the liver parenchyma; E: Hepatobiliary phase shows isointensity or subtle peripheral ring-like enhancement of the tumor; F: T2-weighted image shows isointensity of the tumor.
