Is Doppler sonography measurement of systolic peak frequency reproducible in extracranial carotid arteries?

Population

29 extracranial carotid arteries (25 internal carotid arteries with 10-95% diameter reduction stenoses, 4 normal vessels)

Intervention

Doppler sonography performed twice within three days or less

Outcome

Reproducibility of systolic peak frequency of the internal carotid artery read from the Doppler spectrumsurrogate

Systolic peak frequency derived from Doppler spectrum is highly reproducible for evaluating carotid arteries, unlike mean frequencies from zero-crossing detectors.
