59 year-old male patient with partially necrotic HCC post TACE. (a) Axial contrast-enhanced T1 weighted image obtained at portal venous phase, (b) axial fat suppressed SS EPI DW image at b800. Both demonstrate a partially necrotic HCC with solid enhancing component with restricted diffusion (arrow) and nonenhancing necrotic component hypointense on DW-MRI (short arrows). (c) Magnified b800 DW image shows ROI placement in solid and necrotic components. (d) Fitting diffusion curve in whole HCC lesion. The following parameters were obtained in solid/necrotic HCC components/background liver: D 1.21/1.57/0.77 × 10−3 mm2/s, D* 17.53/9.44/8.03 × 10−3 mm2/s, PF 15.81%/23.33%/21.58%, ADC 1.47/1.97/1.09 × 10−3 mm2/s, and enhancement ratios (during portal venous phase) 113.0%/−16.4%/47.8%.
