From: Role of 18F-FDG PET/CT in assessment of HCC patients after therapeutic interventions compared to DW MRI

Fig. 3

A 56-year-old male patient with a history of HCC at segment V, underwent TACE. It was TR-LR non-viable, yet, with increased peripheral FDG uptake in PET/CT and diffusion restriction in DWI. No definite de novo lesions and also no detected metastatic lesions. MIP image (A) showing focal hepatic right lobar lower segmental increased tracer uptake (black arrow). Arterial (B) and portovenous (C) triphasic CT of the lesion showing traces of lipiodol retention, with no evidence of enhancing residual/recurrent viable tumoral tissue (white arrow). DWI (D) and ADC map (E) of the lesion shows restricted diffusion bright signal within the embolized HCC (white arrow); however, the mean ADC value was elevated measuring 2205 mm2/s. Fused PET/CT images show peripheral increased FDG uptake in the embolized HCC (white arrow), achieving SUVmax of 3.4 (F and G) identical to our cutoff value
