Magnetic resonance colonography. A form of 'virtual colonoscopy'. It is a relatively new imaging modality intended to provide broadly similar information to to conventional fibre-optic endoscopic colonoscopy. [1]

Has the advantage over CT colonography that it does not involve ionising radiation. This is an important consideration if a regular population screening programme is contemplated as the cumulative radiation exposure carries its own risk of malignancy. It also allows imaging of other organs in the abdominal and pelvic cavity.

In addition to screening for colorectal cancer, it has been used in the assessment of patients with inflammatory bowel disease.
