  		Fig. 2A. —47-year-old man with polyp (arrow) with maximum size of 10 mm in sigmoid. Three-dimensional double-contrast MR colonography displays polyp in images with quality similar to that obtained using double-contrast barium enema. Because acquired data set is three-dimensional, rotation of virtual double contrast is possible (A and B). Rotation of virtual double-contrast image in magnified format (C and D) appears to enhance diagnostic confidence.
