Brief Summary:
The goal of this clinical trial is to compare distension quality and patient experience of water and polyethylene glycol preparation as oral contrast media in Magnetic Resonance Enterography (MRE) in patients with Crohn's disease.
Thus, the main question it aims to answer is:
Is water sufficient to interpret MRE from patients with Crohn's disease?
Researchers will compare the standard protocol (polyethylene glycol) with water as bowel distension agent to see if it is possible to obtain a satisfying global distension of small bowel.
Participants will undergo the same procedures as standard care adding questionnaires and replacing water as the bowel distension agent for the MRE for patient randomized into the experimental group.

Detailed Description:
Magnetic Resonance Enterography (MRE) is a key tool for clinicians managing patients with Crohn's disease. This exam has a high performance in the diagnosis of complications and determination of healing rate after medical treatment. Small bowel distension with 1-1.5L of distension agent is mandatory to allow an accurate analysis of disease activity. Indeed, an insufficient distension can lead to false positive (thickened appearance of the collapsed digestive tract). Nowadays, there no consensus on the agent used for bowel distension (polyethylene glycol (PEG), lactulose, mannitol, sorbitol). The major limitation of those agent is their sides effects (e.g. diarrhea, gas bloating, vomiting) that decrease patient adherence to treatment. Some have suggested use of water as distension agent because of its price and its low side effect incidence. Yet its utilization has been limited by the fear of early absorption that may limit bowel analysis.
The aim of our study is to compare standard protocol (polyethylene glycol) with water as bowel distension agent in IBD patients requiring MRE on their ability to obtain a satisfying global distension of small bowel (on a previously validated scale).
Due to the side effects linked to the ingestion of 1.5L of distension agent and the impossibility of evaluating the tolerance of each contrast agent if 2 MREs are carried out on the same day, each the participant will benefit from an MRI using a single preparation modality (water or PEG).
To ensure comparability of the groups, patients will be randomized with 1:1 ratio after stratification on past bowel resection and structuring phenotype. The exams and distension scores will be determined by two radiologists (one expert and one trainee) blinded on patient allocation group. Regarding side effects, patient will fulfill several questionnaires after the exam and at 48h (end of follow-up).
