Vascular Duplex Ultrasound Protocol Carotid

Overview

Combines B mode imaging color Doppler and spectral Doppler to evaluate plaque morphology and hemodynamic significance of carotid disease.

Core Measurements

Peak systolic and end diastolic velocities in common carotid internal carotid and external carotid arteries with plaque characterization.

Interpretation Criteria

Use validated velocity thresholds for stenosis grading and document contralateral disease and vertebral artery flow patterns.

Quality and Documentation

Include longitudinal and transverse images, Doppler waveforms, and clinical correlation with neurologic symptoms for management decisions.
