Ruehm University Hospital Essen, 45122 Essen, NRW, Germany, Department of Radiology, Crete, Crete, Greece ABSTRACT: The aim of this study was to assess MR colonography for the detection of colonic polyps/malignancy. 50 subjects underwent MR colonography prior to conventional colonoscopy. MRC is based on a rectal enema with water in combination with the intravenous application of a paramagnetic contrast agent. MRC correctly identified 20 polyps in 12 patients. Two small polyps seen at colonoscopy were missed by MRC. The MRC concept based on a dark colonic lumen and a bright, contrast enhanced colonic wall appears to be a promising alternative to traditional MRC based on a bright colonic lumen.

PURPOSE To assess whether the detection of colorectal lesions can be improved using high spatial resolution VIBE imaging. MATERIALS AND METHODS 48 patients underwent same-day dark lumen MR colonography (MRC) and conventional colonoscopy (CC) as the standard for the detection of colorectal masses. MRC was performed using contrast-enhanced standard and high spatial resolution T1-weighted 3D VIB...
