Final answer:
A CT scan is both sensitive and specific in distinguishing causes of SBOs. It has a sensitivity of approximately 95% and a specificity of approximately 90%.
Step-by-step explanation:
A CT scan is both sensitive and specific in distinguishing causes of SBOs. Sensitivity refers to the ability of the CT scan to correctly identify true positives, or patients who have SBOs. CT scans have a sensitivity of approximately 95%, meaning that they can accurately detect 95% of SBO cases. Specificity, on the other hand, refers to the ability of the CT scan to correctly identify true negatives, or patients who do not have SBOs. CT scans have a specificity of approximately 90%, meaning that they can accurately exclude SBO cases in 90% of patients.
