Purpose: Assess feasibility of applying magnetization transfer (MT) and dynamic and delayed enhancement (DCE) sequences during MR Enterography(MRE) in children.

Methods: REB approved, in this prospective study, patients =/< 18 years undergoing MRE for suspected or proven inflammatory bowel disease were consented for application of MT and DCE sequenced in addition to standard clinical sequences. These were assessed and prospectively recruited and imaging sequences applied. Imaging was subjectively analysed by two radiologists or a radiologists and physicist in the first arm by consensus for sequence modification.

Results: Inter and intra-reader analysis was undertaken.

Conclusion: DCE is robust, MTR requires further modification.
