Quantitative MRI datasets based on relaxometry and Magnetisation Transfer (MT) sequences could be used as potential biomarkers of disease activity in Inflammatory Bowel Disease. The aim of the study was to measure the repeatability of T2, T1 and MT small bowel measurements following bowel preparation and administration of an anti-spasmodic agent. Inter-observer variations in these measurements were also assessed. The quantitative MRI methods examined showed excellent repeatability for T2 and good repeatability for T1 parameters for both repeatability between visits and reproducibility of results between observers from data of a small group of healthy subjects.
