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

Figure 3 The K^trans, K_ep, V_e and apparent diffusion coefficient among the three groups. A: Bar charts show increasing K^trans, between the normal ileal loop (NIL) and the inflamed terminal ileum (ITI) and pairwise comparisons of them is different (all P < 0.001); B: K_ep between the NIL and the ITI is different (all P < 0.001); C: V_e between the NIL and the ITI is different (all P < 0.001); D: Apparent diffusion coefficient between the NIL and the ITI is different (all P < 0.001). Furthermore, increasing K^trans, K_ep and V_e are shown with activity of CD in remission, mild and moderate-severe CD while decreasing apparent diffusion coefficients are shown (all P < 0.001). ^aP indicate difference with P < 0.001. NIL: Normal ileal loop; ITI: Inflamed terminal ileum.
