Abstract：Objective To explore the diagnostic value of multi-detector row CT (MDCT) imaging and axial post-processing images for acute mesenteric ischemia(AMI).Methods A total of 33 patients with undiagnosed AMI from January 2014 to February 2016 in the First Hospital of Tsinghua University were enrolled.All patients had MDCT;the diagnostic value of MDCT signs combined with axial union post-processing images for AMI was analyzed.Results The sensitivity,specificity,accuracy,negative predictive value and positive predictive value of MDCT in diagnosis of AMI were 100.00％,94.12％,96.97％,100.00％ and 94.12％,respectively.The sensitivities of intestinal wall thickening,intestinal wall hierarchical intensification,mesenteric edema ± stranding sign in MDCT signs in diagnosis of AMI were 93.75％,81.25％ and 81.25％,respectively.The specificities of portal vein/mesenteric vein thrombosis,intestinal wall density increasing,intestinal wall no significant intensification and intestinal wall pneumatosis in diagnosis of AMI were 94.12％,94.12％,94.12％ and 100.00％,respectively.Axial post-processing images showed extents of blood vessel and intestinal tract lesions more clearly.Conclusion MDCT signs and axial post-processing images have important significance for etiological analysis and extent definition of AMI.
