Wavelet-based archPWV may refine CMR stiffness measures at reduced resolution; leaves open clinical outcome validation in patients.
Does a wavelet-based method improve the estimation of aortic pulse wave transit time in CMR compared to Fourier-based and time domain methods in healthy subjects?
A novel wavelet-based method for estimating aortic pulse wave transit time by CMR provides better correlation with age and cfPWV and is more robust to low temporal resolution than traditional methods.
