Abstract
Acute mesenteric ischemia (AMI) has an acute onset and a high mortality rate with nonspecific clinical presentation and is difficult to diagnose. In recent years, due to fast submillimeter scanning and subtle three-dimensional reconstruction, 64-row multi-slice CT can distinctly demonstrate the stenosis and occlusion of the mesenteric vessels, assess the alteration of morphology and blood perfusion of the intestinal wall and mesentery, and promptly and accurately diagnose AMI, intestinal infarction and its etiology. Therefore, CT has become the most valuable and first-line diagnostic modality for evaluating patients with suspected AMI. AMI has different and complicated CT findings due to different etiology, pathology, extent, position, as well as with or without mural hemorrhage or infection. In this article, we systematically review the multi-slice CT manifestations of AMI and its diagnostic value in various causes of AMI in different stages.
