Structured PICO

Does direct carotid Doppler interrogation using real-time sound spectrum analysis improve diagnostic accuracy compared to indirect periorbital Doppler screening in patients with symptomatic cerebrovascular disease?

P
Population
Patients studied for symptomatic cerebrovascular disease
I
Intervention
Direct carotid Doppler interrogation using real-time sound spectrum analysis
C
Comparator
Indirect periorbital Doppler screening
O
Outcome
Sensitivity, specificity, and predictive value to detect operable extracranial carotid occlusive disease (compared to independently assessed contrast arteriograms)surrogate

Real-time spectrum analysis of direct carotid Doppler signals substantially improves the diagnostic accuracy of noninvasive identification of operable carotid artery disease compared to periorbital Doppler.
