MRI of gastrointestinal function – from research to clinical practice

Patients with functional gastrointestinal disorders (FGIDs) have persistent and recurring GI symptoms without a structural or biochemical abnormality, hence common FGIDs such as irritable bowel syndrome (IBS), functional dyspepsia or functional abdominal pain may have essentially normal radiological and endoscopic investigations. Imaging the physiology of GI function is complicated and limited by technical difficulties related to respiratory and peristaltic movement. Although established clinical investigations such as computed tomography (CT) and endoscopy provide anatomical evaluation of the digestive tract, both require bowel preparation and do not directly assess digestive function.
