- Bland-Altman mean biases and limits of agreement (LA) for comparisons between 4D flow MRI aoPWV values and carotid-femoral PWV (Cf-PWV) as well as the ascending aorta Bramwell-Hill PWV (BH-PWV). Bias was defined as 4D flow MRI aoPWV – Cf-PWV or BH-PWV. S1, S2 and S3: Strategies 1, 2 and 3, respectively. TTc, TTw and TTf: transit times estimated using cross-correlation, wavelets and Fourier transforms, respectively
