Dynamic contrast-enhanced magnetic resonance imaging and diffusion-weighted imaging in the activity staging of terminal ileum Crohn's disease

Figure 4 Correlations of inflamed terminal ileum with Crohn’s Disease Activity Index and Crohn’s Disease Endoscopic Index of Severity in Crohn’s disease. A and C: Scatterplots show positive correlation of K^trans, K_ep and V_e and negative correlation of apparent diffusion coefficient in inflamed terminal ileum of Crohn’s disease patients with Crohn’s Disease Activity Index score; B and D: Positive correlation of K^trans, K_ep and V_e and negative correlation of apparent diffusion coefficient in inflamed terminal ileum of Crohn’s disease patients with Crohn’s Disease Endoscopic Index of Severity score. CDAI: Crohn’s Disease Activity Index; CDEIS: Crohn’s Disease Endoscopic Index of Severity; ADC: Apparent diffusion coefficient.
