abstract：BACKGROUND:Maintenance of mucosal healing is a primary goal when treating Crohn's disease (CD). Endoscopy is the most precise method for the assessment of mucosal healing, but is considered overly invasive for patients with CD. In contrast, CT enterography (CTE) is less invasive, but little is known about the correlati...
