Overview
Gastric real time high resolution MRI may be helpful in the diagnosis of gastroparesis and other motility disorders of gastrointestinal tract. Findings on MRI suggestive of gastroparesis include reduced antral peristaltic wave propagation and reduced gastric motility index. The advantages of MRI include being noninvasive, operator independence with no ionizing radiation exposure.
MRI

- Findings on MRI suggestive of gastroparesis include:[5]
- Reduced antral peristaltic wave propagation
- Reduced gastric motility index
- The advantages of MRI include:
- Accurate and reproducible
- Noninvasive
- Operator independence
- No ionizing radiation exposure
