Why the study?
Does MDCT compared to single-detector CT affect the probability of subsequent thromboembolic events in patients with suspected acute PE and negative CT results?
Population
198 patients with suspected acute pulmonary embolism (PE) and negative results on CT pulmonary angiography
Comparison
MDCT (2-mm collimation and pitch of 1) vs Single-detector CT
Design
Cohort
Follow-up
6 months

Suggests detecting smaller peripheral emboli with MDCT may not improve clinical outcomes; leaves open whether.
Does MDCT compared to single-detector CT affect the probability of subsequent thromboembolic events in patients with suspected acute PE and negative CT results?
Increased visualization of smaller, more peripheral arteries afforded by MDCT does not affect clinical outcomes in patients with suspected acute PE and negative CT results compared to single-detector CT.
