Power Doppler Imaging: Initial Evaluation as a Screening Examination for Carotid Artery Stenosis

Abstract

The A(z) value for power Doppler imaging compares well with that for mammography, a generally accepted screening examination, and with most other imaging examinations. Power Doppler imaging is likely to be a reasonably accurate and cost-effective screening examination for carotid artery stenosis in asymptomatic populations.
