Figure 1From: Utility of the diffusion-weighted imaging for activity evaluation in Crohn’s disease patients underwent magnetic resonance enterographyDetermine the optimal b value in DWI with a learning cohort of patients. The mean CNR and SNR of four b value sequences. The unit of b value is s/mm2(A). The ADC values of four b value sequences. The unit of ADC is 10−3 mm2/s (B).Back to article page
