Journal Article
Dellschaft, N., Murray, K., Ren, Y., Marciani, L., Gowland, P., Spiller, R., & Hoad, C. (2025). Assessing Water Content of the Human Colonic Chyme Using the MRI Parameter T1: A Key Biomarker of Colonic Function. Neurogastroenterology and Motility, https://doi.org/10.1111/nmo.14999

Background
The human colon receives 2 L of fluid daily. Small changes in the efficacy of absorption can lead to altered stool consistency with diarrhea or constipation. Drugs and formulations can also alter colonic water, which can be assessed using...
