Preferred Abstract (Original):

The study was performed to compare contrast–enhanced dark lumen MR colonography (MRC) with bright lumen MR colonography (not requiring i.v. contrast administration) based on 2D TrueFISP images for the detection of colorectal masses. 31 patients underwent both bright-and dark lumen MRC. MR findings were compared to conventional endoscopy. While dark-lumen MRC was able to visualize all colorectal

masses larger than 5mm, bright lumen MRC was less sensitive. With the bright-lumen approach false-positive results were present in 5 patients

, whereas dark- lumen MRC did not provide any false-positive findings
