Overview
There are no MRI findings associated with bowel obstruction . However, a MR enterography may be helpful in the diagnosis of complications of bowel obstruction, which include ischemia, perforation and necrosis. MR enterography is also useful in identifying the site of obstruction.
MRI
- There are no MRI findings associated with bowel obstruction . However, a MR enterography may be helpful in the diagnosis of complications of bowel obstruction, which include:[1][2]
- Ischemia
- Perforation
- Necrosis
- MR enterography is also useful in identifying the site of obstruction, especially in low-grade bowel obstruction such as those in cases of Crohn's disease, and in younger patients to reduce exposure to radiation.
- MR enterography has a higher sensitivity and specificity than helical CT in detecting bowel obstruction.[3]
Limitations of MR enterography
- Lengthy wait for image processing
- Repeated breath holding is required
