Why the study?
Does phonoangiography accurately estimate residual lumen diameter compared to radiographic carotid arteriograms in patients with suspected carotid stenosis?
Does phonoangiography accurately estimate residual lumen diameter compared to radiographic carotid arteriograms in patients with suspected carotid stenosis?
Phonoangiography provides a noninvasive method to accurately estimate residual lumen diameter in patients with carotid bruits, correlating well with radiographic arteriography.

Phonoangiography may support noninvasive carotid lumen estimation; Level 4 data leaves open prospective validation before clinical use.
Gruber et al. (1975) studied this question.
