Abstract Objective To investigate the diagnostic capability of multidetector computed tomography for detecting nonocclusive mesenteric ischemia (NOMI). Methods We studied 11 NOMI patients and 44 controls. Radiologists evaluated the CT images for the presence of bowel ischemia and measured the diameters of the superior mesenteric artery and the superior mesenteric vein (DSMA and DSMV). We also performed linear discriminant analysis (LDA) using DSMA and DSMV. Results All NOMI patients presented with more than 2 CT findings of bowel ischemia. DSMA and DSMV were
significantly smaller in NOMI patients than in the controls (p \ 0.01). At the optimal cut-off values for DSMA (6.5 mm), DSMV (9.0 mm), and the Z value in LDA (0.93), sensitivity and specificity were 81.8 and 81.8; 81.8 and 88.6; and 81.8 and 97.7 %, respectively. Conclusions DSMA and DSMV were significantly smaller in NOMI patients than in the controls and DSMV is a more significant parameter than DSMA.
