No results posted yet for this study

Summary

Purpose: To investigate the different sound spectrum of carotid arteries and to analyze its relationship to the vessel disease, and to build a new biomarker about vascular disorder.

Methods: To record the carotid phonoangiography with digital stereoscopy and analysis the spectrum with different algorithm such as FFT, wavelet, entropy, complexity, and HHT. The results will be correlated and comparison to the finding in clinical, carotid Doppler and duplex, CTA, MR, and catheter angiography.

Statistics:

The significance of difference between parameters was computed using t-tests or paired t-test etc. A p value \<0.05 is defined as significant.
