Fig. 4From: Mucosal healing assessment in Crohn’s disease with normalized iodine concentration from dual-energy CT enterography: comparison with endoscopyA 52-year-old man with Crohn’s disease did not achieve endoscopic mucosal healing after 8 months of therapy. a Endoscopic images of the terminal ileum show ulcerating inflammation before infliximab treatment. b Posttreatment endoscopic images still show ulcerating inflammation. c On the posttreatment enteric phase axial CTE image, the wall of the terminal ileum is thickened. d ROI1 was placed in the thickened wall of the terminal ileum in these iodine-based material decomposition images, and ROI2 was placed in the artery at the same level. The NIC in this thickened wall of the terminal ileum was 0.671Back to article page
