Overview
Among patients with ischemic colitis, the CT scan shows mild to moderate diffuse bowel wall thickening and marked hyperenhancement of the mucosa.
CT
CT scan results for ischemic colitis are as follows:[1][2][3][4]
- CT scans are often used in the evaluation of abdominal pain and rectal bleeding, and may suggest the diagnosis of ischemic colitis.
- First study in assessing the patient with abdominal pain.
- Indirect evidence of ischemic colitis, such as mural thickening or ascites.
- Not very specific for bowel infarction.
