Benign focal liver lesions: The role of magnetic resonance imaging

Figure 9 A 42-year-old male underwent ultrasound examination for abdominal discomfort demonstrating diffuse steatosis with a hypoechoic nodule in S6. Liver magnetic resonance imaging confirmed diffuse steatosis and a hypointense lesion on T1-weighted sequences, hyperintense on long TR sequences and on the ADC map. During dynamic study after intravenous contrast injection, the lesion presents centripetal enhancement and is hypointense on the hepatobiliary phase. These features are consistent with hemangioma.
