Key result
MRI-based cepstral analysis noninvasively separates incident and reflected waveforms comparably to wave intensity analysis.
Why the study?
Few studies have examined the noninvasive determination of propagation parameters, despite the clinical relevance of reflected wave amplitude and arrival time in cardiovascular diseases.
Does cepstral analysis of PCMR-derived blood velocity accurately determine propagation parameters in the carotid artery compared to wave intensity analysis?

Does cepstral analysis of PCMR-derived blood velocity accurately determine propagation parameters in the carotid artery compared to wave intensity analysis?
Cepstral analysis of PCMR data offers a promising noninvasive approach to separate measured velocity waveforms into incident and reflected components in the carotid artery.
Ayadi et al. (2022) conducted an observational in Cardiovascular diseases (n=20). Cepstral analysis of blood velocity vs. Wave intensity analysis (WIA) was evaluated on Propagation parameters (arrival time, attenuation coefficient, reflection amplitude, and reflection coefficient). Cepstral analysis of blood velocity measured by phase-contrast MRI successfully separated incident and reflected waveforms noninvasively, yielding reflection coefficients comparable to wave intensity analysis.
