MR diffusion weighted images during sunitinib therapy. Transverse enhanced MR T1-weighted images (A, B) and MR diffusion weighted images (DWIs) for estimated apparent diffusion coefficient (ADC) (C, D) at baseline and after 2-week of sunitinib therapy in the same 47-year-old man with HCC (arrows). After two weeks of treatment with sunitinib, there was an increase in ADC value from 0.86 × 10-3 mm2/s to 0.94 × 10-3 mm2/s.
