Magnetic resonance imaging assessment of body composition parameters in Crohn's disease.

Background: Body composition, currently evaluated by computed tomography scan, is related to poor evolution and severity of Crohn's disease (CD). Few MRI studies have been performed, yet it is the most commonly used imaging modality for the surveillance of the disease.

Aim: Evaluate the feasibility of MRI body composition measurement and compare the variation according to the activity of the disease.
