Overview
Computerised axial tomographic angiography should be performed as soon as possible in order to diagnose mesenteric ischemia becasue of its ability to define the arterial anatomy and demonstrate the site of occlusion.
CT
- Computerised axial tomographic angiography with intravenous contrast is the diagnostic test of choice for mesenteric ischemia regardless of the etiology.[1]
Patient #1: CT images of patient with ischemic bowel demonstrates pneumatosis and portal venous gas
Patient #2: CT images demonstrate mesenteric ischemia with marked atherosclerosis of arteries
