A 40-year-old male patient with moderate cirrhosis and a single HCC lesion in segments VIII, VII, V, and IV. A Early arterial phase, B delayed phase C T2WI, D diffusion WI E ADC map, F in-phase gradient echo, G opposed phase gradient echo H in-phase gradient echo measuring the fat fraction within the lesion, I opposed phase gradient echo measuring the fat fraction within the lesion.The lesion elicits moderate high T2 signals with restricted diffusion and shows early non-rim APHE and non-peripheral contrast washout. Hepatic fat fraction: 5.8% (Mild steatosis). Major HCC features: non-rim APHE (early), non-peripheral “washout” (late) and size = 13.5 × 14.5 cm. Ancillary HCC features favoring malignancy: Moderate T2 hyperintensity, restricted diffusion and fat sparing in solid mass “Relative paucity of fat in solid mass relative to steatotic liver”: (fat fraction in the lesion = 0%)
