Why the study?

Does the 2D-XC method improve the reproducibility of estimating aortic pulse wave velocity compared to established TT or FOOT methods?

Key Points

To assess the reproducibility of a two-dimensional cross-correlation technique against standard transit-time and foot-to-foot approaches for measuring aortic pulse wave velocity.
Evaluated a two-dimensional cross-correlation (2D-XC) algorithm applied to two-dimensional phase-contrast magnetic resonance (2D PCMR) velocity data.
Compared 2D-XC directly against established transit-time (TT) and foot-to-foot (FOOT) estimation methods.
The 2D-XC method achieved superior reproducibility in estimating aortic pulse wave velocity relative to both the TT and FOOT methods.
