Abstract Background Variable sequences can be used in MR enterography, and no consensus exists for the best protocol in children with Crohn disease. Objective To compare the lesion detectability of various MR enterography sequences and to correlate the findings of these sequences with the Pediatric Crohn’s Disease Activity Index (PCDAI) in children with Crohn disease. Materials and methods Children with clinically or pathologically confirmed Crohn disease underwent MR enterography, including a single-shot fast spin-echo (SSFSE) sequence, motility imaging (coronal 2-D balanced fast field echo), diffusionweighted imaging (DWI), and dynamic contrast enhancement imaging (including arterial, portal and delayed phases). The lesion detectability of each sequence was graded 0–2 for each involved bowel segment. The lesion detectability and PCDAI result on different sequences were compared using the weighted least squares method and Student’s t-test, respectively.
