Objective To summarize the manifestations of acute mesenteric ischemia (AMI) on multidetector computed tomography (MDCT) and the diagnostic value of MDCT in the prognosis of AMI. Method Recent studies on pathophysiology, CT features, and prognosis of AMI were retrieved and reviewed. Results Vascular insufficiency of AMI could occur as a result of mesenteric arterial embolism, arterial thrombosis, venous thrombosis, or nonocclusive. Two stages of AMI, early and late, were associated with distinct prognosis. In early ischemia, the lesions were reversible. The late AMI was characterized by the development of irreversible transmural necrosis. A delayed diagnosis leaded to considerable mortality. MDCT findings in AMI could be divided into imaging findings related to vascular insufficiency and ischemic intestinal injury. Pneumoperitoneum could be considered a sign of transmural necrosis in the AMI. While, other imaging features predicting transmural necrosis were controversial because of the heterogeneity of diagnostic tests. Conclusions AMI is a life-threatening abdominal emergency. Early diagnosis can improve the prognosis of patient. It is important for radiologists to identify prognostic features for differentiating early from late forms of AMI.
