Coeliac disease (CD) is an autoimmune disease which affects 1 in 100 people. There is no cure and the only treatment is a lifelong gluten free diet. This study aims to improve our understanding of the functional motility disorder associated with CD using MRI. Whole gut transit time (WGTT), measured using MRI transit markers, was significantly delayed in the coeliac patients compared to helathy controls (p<0.04). The MRI gut transit test is quick and is acceptable to patients and could help long term monitoring and follow up, complementing existing more invasive techniques.
