Helical CT accuracy for pulmonary embolism remains inadequately evaluated; leaves open the safety of withholding anticoagulation after negative scans.
What is the sensitivity and specificity of helical CT for diagnosing pulmonary embolism, and is it safe to withhold anticoagulation after a negative scan?
The diagnostic accuracy of helical CT for pulmonary embolism has not been adequately evaluated, and the safety of withholding anticoagulation based on a negative scan remains uncertain.
Rathbun et al. (2000) studied this question.
