Table 2. Comparisons of ΔADC (Pre-Treatment – Post-Treatment) between Improved and Unimproved Lesions According to Reference Standard, i.e., Endoscopy, after Therapy.

	Improved (n = 33)*	Unimproved (n = 4)*	P
Reader 1	-0.65 ± 0.58	0.06 ± 0.15	0.022
Reader 2	-0.68 ± 0.56	0.10 ± 0.26	0.025

Data are mean ± SD in × 10^-3 mm²/s. ^*Improved lesions include complete remission or reduced inflammation. Unimproved lesions include unchanged or increased inflammation. ADC = apparent diffusion coefficient
