74 years old male patient underwent TACE. PET/CT uptake with no diffusion restriction in TR-LR viable lesion. A Axial CT venous phase showing focal peripheral lipiodol concentration (black arrow). B–D Arterial (B), venous (C) and delayed (D) DCE-MRI showing faint APHE with washout (red arrow) (TR-LR viable). E, F DWI (E) and ADC map (F) showing no diffusion restriction in the DWI with an iso-intense signal to the liver parenchyma in the ADC map. ADC of the lesion measures about 1.36 × 10−3 mm2/s (above the cut off value of 1.32). G–I Fused PET/CT images showing mild peripheral increased FDG uptake achieving SUV max of 3.4 while the mean SUV of the liver parenchyma was 2.78. (SUV ratio is 1.22)
