Abstract
Objective
To investigate the diagnostic capability of multidetector computed tomography for detecting non-occlusive 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 (D
SMA and D
SMV). We also performed linear discriminant analysis (LDA) using D
SMA and D
SMV.
Results
All NOMI patients presented with more than 2 CT findings of bowel ischemia. D
SMA and D
SMV were significantly smaller in NOMI patients than in the controls (p < 0.01). At the optimal cut-off values for D
SMA (6.5 mm), D
SMV (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
D
SMA and D
SMV were significantly smaller in NOMI patients than in the controls and D
SMV is a more significant parameter than D
SMA.
