Key result
Analysis of blood velocity waveforms using ultrasonic methods proved capable of detecting even minor carotid artery stenosis, whereas arterial wall movement showed no change with disease.
Why the study?
Can ultrasonic methods (blood velocity waveform analysis and arterial wall movement measurement) detect carotid artery disease?
Observational
Can ultrasonic methods (blood velocity waveform analysis and arterial wall movement measurement) detect carotid artery disease?
Analysis of blood velocity waveforms using ultrasonic methods shows potential as a non-invasive technique for detecting minor carotid artery stenosis.
May support non-invasive detection of minor carotid stenosis via velocity waveforms; leaves open validation in prospective cohorts before clinical use.
The use of both Doppler and pulse-echoultrasonic equipment for detecting carotid artery disease is discussed. The need for new non-invasive techniques, capable of detecting small stenoses, is demonstrated and the development of two techniques (analysis of blood velocity waveforms and the measurement of arterial wall movement) is described. The arterial wall movement showed no change with disease, but analysis of the blood velocity waveforms proved capable of detecting even minor stenosis in some cases. Methods for confirming these preliminary results are discussed.

Lunt et al. (1978) conducted an observational in Carotid artery disease. Ultrasonic methods (analysis of blood velocity waveforms and measurement of arterial wall movement) was evaluated on Detection of carotid artery stenosis. Analysis of blood velocity waveforms using ultrasonic methods proved capable of detecting even minor carotid artery stenosis, whereas arterial wall movement showed no change with disease.
