Key result
Carotid to femoral artery tape measure distance multiplied by 0.8 showed the best agreement with MRI reference aortic path length (mean difference 0.26 cm; not statistically significant).

Which body surface distance estimate best corresponds with the real travelled aortic path length measured by MRI for carotid-femoral pulse wave velocity assessment?
Mean Difference: 0.26
p-value: p=not statistically significant
The tape measure distance from the carotid to femoral artery multiplied by 0.8 provides the most accurate estimate of real aortic path length for pulse wave velocity measurement.
Huybrechts et al. (2011) conducted a cross-sectional in Healthy (n=98). Tape measure distance from carotid to femoral artery (CA-FA) multiplied by 0.8 vs. MRI reference distance was evaluated on Agreement with reference aortic path length measured by MRI (Mean difference 0.26 cm, p=not statistically significant). Carotid to femoral artery tape measure distance multiplied by 0.8 showed the best agreement with MRI reference aortic path length (mean difference 0.26 cm; not statistically significant).
