One series of 32 patients reported a sensitivity of 93%, a specificity of 100%, and an accuracy of 94% for CT scanning in the detection of obstructions. [21] Another series reported a sensitivity of 92% and specificity of 71% in the correct identification of partial or complete SBO. [11] Additional studies have shown sensitivities above 95% for CT scanning in identifying obstructions and its complications. [5]
