Optimal b value of diffusion-weighted imaging on a 3.0T magnetic resonance scanner in Crohn’s disease

Table 3 Mean signal-to-noise ratios of four b value diffusion-weighted imaging sequences

	b = 800	b = 1500	b = 2000	b = 2500
b = 800	113.98 ± 48.92	P = 0.007	P < 0.01	P < 0.01
b = 1500	P = 0.007	84.77 ± 33.24	P = 0.004	P = 0.001
b = 2000	P < 0.01	P = 0.004	53.58 ± 23.45	P = 0.567
b = 2500	P < 0.01	P = 0.001	P = 0.567	47.58 ± 29.67

Unit of b value in diffusion-weighted imaging is s/mm².
