 High-speed MRI, with a scan speed of 1 second per scan, allows the development of cine MRI, which provides diagnostic methods for examination of peristalsis in the digestive tract. It also enables rendering MR hydrograms, which can be used to visualize fluid in the gastrointestinal tract using the same scanning principle as MRCP. In addition, MR colonography provides images of the contents in the obstructed intestine or in the colon by increased or decreased signals, using fat-suppressed T1 weighted MRI. Recently, a new technique for diagnostic imaging using diffusion-weighted MRI was introduced. To diagnose obstruction or adhesion in the small intestine, virtual colonoscopy avoiding radiation exposure can be achieved using these new techniques. Here, we present practical methods using these new techniques and describe their clinical application.
