69-year-old male patient with HCV cirrhosis and HCC treated with radioembolization (RE). Pre-treatment MRI: HCC (arrows) demonstrates restricted diffusion on high b value DWI (b 800) (a) and ADC map (b). Post-treatment MRI at 6w post RE shows unchanged diffusion restriction on DWI (b 800) (c) with low ADC (d). Contrast-enhanced-T1 weighted images obtained during the portal-venous phase at baseline (e) and at 6 months (f) show stable disease at 6 months. Corresponding histogram distribution of vADC before (blue, vADC median 1.12 × 10− 3 mm2/s, vADC mean 1.12 × 10− 3 mm2/s) and 6w after RE (red, vADC median 1.17 × 10− 3 mm2/s, vADC mean 1.19 × 10− 3 mm2/s, ΔvADC median 4%, ΔvADC mean 3%) shows an almost identical distribution after RE (g)
