A commercialized CT virtual colonoscopy system (V3D Colon, Viatronix Inc.) was enhanced to support dark-lumen MR colonography procedure. A volume rendering technique was developed to display 3D endoluminal view for polyp detection using MR images. The new technique allows rendering accurate 3D depth for spatial-intensity-inhomogenety images. The user graphics interface and workflow remained the same as before. That greatly saves training time when old user start using new modality. The new system was evaluated on 12 MR cases. For the good and moderate imaging quality cases, the results are promising
