Is CTA or MRA preferred for assessment of mesenteric ischemia?
Both assess the mesenteric arteries and veins well. However, CT may better depict some stigmata of acute bowel ischemia/infarction such as pneumatosis, portal venous gas, and pneumoperitoneum. Furthermore, CTA is much faster to perform compared to MRA, which is an advantage for the evaluation of potentially unstable patients.
