a The MR images of a 67-year-old man. Pre-radiotherapy, the axial T2W image shows a hypointense DIL in the right apex (c) and the DIL volume was 4.8 cm3 in the ADC image and the ADC value was 572 × 10−6 mm2/s (a). Post-radiotherapy, the axial T2W image shows the diffusely intermediate signal of the right apex (d) and the DIL volume was not detected in the ADC image, and the ADC value was 1210 × 10−6 mm2/s. These finding indicate a good response to the treatment (b). b The MR images of a 77-year-old man. Pre-radiotherapy, the axial T2W image shows a hypointense DIL in the right midgland (c) and the DIL volume was 4.6 cm3 in the ADC image and the ADC value was 820 × 10−6 mm2/s (a). Post-radiotherapy, the axial T2W image shows a diffusely intermediate signal of the right midgland (d) and the DIL volume was 0.38 cm3 in ADC image, and the ADC value was 920 × 10−6 mm2/s. These findings indicate a poor response to the treatment (b). c The MR images of a 64-year-old man. Pre-radiotherapy, the axial T2W image shows a hypointense DIL in the left peripheral zone (c) and the DIL volume was 1.2 cm3 in the ADC image and the ADC value was 651 × 10−6 mm2/s (a). Post-radiotherapy, the axial T2W image shows the diffusely intermediate signal of the left midgland (d). Post-radiotherapy, the DIL volume was 0.72 cm3 in ADC image and the ADC value was 736 × 10−6 mm2/s. These findings indicate a poor response to the treatment (b)
