Synopsis

MR Enterography forms the mainstay of imaging for inflammatory bowel disease in adults and children. Ultrasound and CT are useful adjuncts in specific circumstances. Assessment of inflammation in IBD requires a multi-sequence approach using fluid-sensitive, diffusion-weighted and contrast enhanced sequences. Currently it is difficult to assess accurately, the relative contributions of inflammation and fibrosis within a given area of disease though this is possible. Newer techniques such as magnetisation transfer factor and quantified dynamic assessment of gut motility offer some promise in these areas.
