Duplex ultrasound may lead to misclassification of carotid artery stenosis.

ABSTRACT:

Objective

Carotid duplex ultrasonography (CDUS) is often the first-line imaging modality for clinical evaluation of carotid disease. Despite improved equipment and standardization of vascular imaging protocols, CDUS can be technician-dependent and unreliable in calcified blood vessels. The aim of this study was to assess variability in carotid stenosis severity measured using CDUS compared with reference high-resolution magnetic resonance imaging (MRI).

Methods

In this prospective cohort study designed to study long-term brain health outcomes, we enrolled 123 participants with a diagnosis of asymptomatic carotid disease and/or ≥2 cardiovascular risk factors between the ages of 50 to 85 years from vascular and cardiology clinics in Tucson, Arizona, for the ongoing Carotids an
