Overview
Fluoroscopy barium studies rarely used in diagnosis of ischemic colitis. Contrast enema is abnormal in 90% of patients but is rarely used for diagnostic purposes.
Other imaging findings
- Fluoroscopy barium studies may be used in diagnosis of ischemic colitis.
- Contrast enema is abnormal in 90% of patients but is rarely used for diagnostic purposes.[1]
- The findings are:
- Segmental region of abnormality
- Thumbprinting which is classically obliterated by air insufflation,
- Spasm
- Ulcerations serrated mucosa
- Stricture from fibrosis
- Barium enema should be avoided in cases where there is a suspicion of gangrene or perforation.
- Barium enema also makes the later use of angiography or endoscopy more difficult because of residual contrast agent.
