Contrast-enhanced MR imaging of the small bowel was performed in 12 healthy volunteers at 1.5T and 7T. Quality of MR images was directly compared between 1.5T and 7T. Image impairment by artifacts was separately investigated for 1.5T and 7T. MR images of the small bowel at 7T can be generated with an image quality that fulfills diagnostic requirements. Despite an increasing number of artifacts at 7T, tissue contrast and image quality were equivalent as compared with those achieved with 1.5T.
