Figure 3

Early MRI 3 days after HDR-BT. Early DWI (A) and corresponding ADC map (B) performed 3 days after HDR-BT (same patient as in Figure 1) reveal a decrease in mean ADC by 27.1% to 0.94 × 10-3 mm2s-1. The ROI within the lesion indicates an ADC value of 1.09 × 10-3 mm2s-1 in this slice of the ADC map (arrow). T1w Gd-EOB-DTPA enhanced MR image in hepatobiliary phase (C) indicates no relevant change in size of the treated lesion (24.1 cm3).
