title: Duplex ultrasound imaging of the carotid arteries.
abstract: Duplex ultrasound examination of vessels includes both high resolution imaging in real time mode and rangegated Doppler with spectral analysis. Velocity spectra are calculated, and blood velocity ratios are determined. The duplex ultrasound examination seems to be a suitable method for screening of patients for angiography.
