Why the study?
Does a negative helical CT scan safely exclude clinically important pulmonary embolism compared to negative or low-probability scintigraphy in adult patients evaluated for possible PE?

A negative helical CT scan is as reliable as a negative or low-probability V-P scan for safely excluding clinically important pulmonary embolism and withholding anticoagulation.
No takes yet. Share an insight, caveat, or question.
Negative CT scans were associated with low subsequent PE rates similar to V-P scans; supports withholding anticoagulation but leaves open need for randomized confirmation.
Goodman et al. (2000) studied this question.
