Water used to distend the colon for MR-Colonography harbours the risk of spillage and may be associated with more discomfort than air or CO2. Using a short TE-sequence to mitigate susceptibility effects, five volunteers and five patients underwent air-distended MR colonography. The volunteers were examined a second time using water for colonic distension. Following intravenous administration of paramagnetic contrast image quality was sufficient with both techniques to assess the enhancing colonic wall and detect colorectal masses. Colonic wall enhancement was superior with water distension however (p<0.05). Discomfort levels for air and water were not different
