OBJECTIVE. We report our experience with thin-collimation helical CT in a population of
patients suspected of having pulmonary embolism. CONCLUSION. Thin-collimation helical CT
provided technically acceptable examinations for pulmonary embolism in 360 patients (97%).
In this population, CT revealed pulmonary embolism in 104 patients (29%), negative
findings in 217 patients (59%), indeterminate findings in 39 patients (10%), and
alternative diagnoses in 65% of patients with negative or inconclusive findings.
Ventilation-perfusion scanning and Doppler sonography of the lower extremities were
performed in 158 (44%) and 133 patients (37%), respectively, whereas pulmonary angiography
was performed in 27 patients (7.5%). The estimated false-negative rate of helical CT was
5%.
