Overview
In ischemic colitis ultrasound has limited use because of bowel gas, but may show luminal thickening over the affected segment and hypoechoic wall due to edema. Limited use due to overlying bowel gas, operator-dependent quality, and poor sensitivity for low flow vessel disease.
Ultrasound findings
- In ischemic colitis ultrasound has limited use because of bowel gas, but may show:[1][2][3]
- Luminal thickening over the affected segment.
- Hypoechoic wall due to edema.
- Areas of increased echogenicity if hemorrhage occurs.
- Echogenic foci with shadowing if intramural gas presents.
- Reduced peristalsis may be observed.
