Cure8 research brief
Reference MRI measurements of colon length in adolescents help radiologists and clinicians detect abnormal colonic anatomy when evaluating children with difficult-to-treat constipation or suspected structural problems.
Pediatric gastroenterologists, radiologists, clinicians caring for adolescents with suspected IBD or therapy-resistant constipation, researchers studying pediatric bowel anatomy, and parents of adolescents undergoing MRI-enterography.
This was a retrospective analysis of 81 adolescents (median age 15) who underwent MRI-enterography between 2016–2020. Researchers measured colon segments on coronal T2-weighted MRI using 3D multiple-point measurements and reported mean total colon length, lengths indexed to body surface area (BSA), and rectosigmoid lengths with variability.
Colon length correlated with age, height, weight, and BSA; BSA showed a strong association in multivariable analysis. The study provides reference values (total colon length ~116 cm mean; total colon length/BSA ~72.9 cm/m mean) that may be useful as normative comparators on pediatric MRI when assessing for abnormal anatomy.
This summary is based on the article abstract (retrospective study of 81 patients). The study excluded children with colonic inflammation and those meeting Rome-IV criteria for constipation; values reflect adolescents aged 11–17 and may not apply to other age groups or inflamed colons.

MRE is a key radiation-free imaging tool for children with Crohn’s disease; this review summarizes its clinical utility and how it fits with other pediatric-focused diagnostic approaches in Japan.
MRE is a widely used, noninvasive test that increasingly helps characterize disease phenotype and prognosis in Crohn's disease and IBD, which can affect monitoring and treatment planning.
Baseline MRE features may help predict which Crohn's strictures will not improve with advanced medical therapy, informing monitoring and surgical planning. Better stratification could guide decisions about earlier...
