Instructions And Patient Preparation

Anatomical Region
Enterography (MRE)
Field Strength
3.0T
Coil
See the Coil Configuration row in the first parameters table below (varies by sequence).
Position & Landmark
Feet first, supine. Landmark: center of the coil in use (typically central to the ROI).
Contrast
Weight-based gadolinium contrast per your institution’s protocol, supervising radiologist, and the agent’s FDA prescribing information. Postcontrast sequences are marked +C.
