The accuracy of the CT scan depends on whether a small bowel obstruction (SBO) is present.SBO absent

Intestinal mesenteric edema
Bowel dilatation
Bowel wall thickening
Intestinal mesenteric stranding
Evidence of adjacent solid organ infarctions to the kidney or spleen, consistent with a cardiac embolic shower phenomenonIn embolic acute intestinal ischemia, CT-Angiography can be of great value for diagnosis and treatment. It may reveal the emboli itself lodged in the superior mesenteric artery, as well as the presence or absence of distal mesenteric branches.Late findings, which indicate dead bowel, include:

Intramural bowel gas
Portal venous gas
Free abdominal air

Angiography
As the cause of the ischemia can be due to embolic or thrombotic occlusion of the mesenteric vessels or nonocclusive ischemia, the best way to differentiate between the etiologies is through the use of mesenteric angiography. Though it has serious risks, angiography provides the possibility of direct infusion of vasodilators in the setting of nonocclusive ischemia. Treatment
The treatment of intestinal ischemia depends on the cause and can be medical or surgical. However, if bowel has become necrotic, the only treatment is surgical removal of the dead segments of bowel.In non-occlusive disease, where there is no blockage of the arteries supplying the bowel, the treatment is medical rather than surgical.
