63 years old male patient underwent TACE. PET/CT uptake with diffusion restriction in TR-LR viable lesion. A, B Axial arterial phase (A) and venous phase (B) CT images showing embolized lesion with heterogeneous lipiodol concentration, APHE and washout (red arrow). C–E Axial arterial (C), venous (D) and delayed (E) dynamic contrast MRI images also showing APHE, delayed washout and delayed capsular enhancement (TR-LR viable). F–H DWI (F) and ADC map (G, H), the lesion is iso-intense in the DWI with low ADC value compared to the adjacent liver, the mean ADC of the lesion is 1.12 × 10−3 mm2/s. I–K Axial PET/CT fused images showing increased FDG uptake in the residual lesion achieving SUV max of 2.59 while the mean SUV of the liver was 1.66 (SUV ratio is 1.56)
