Objective: Carotid-femoral pulse wave velocity (PWV) is the gold standard method for determination of arterial stiffness. Path lengths are commonly determined by tape measure, which may not correspond to anatomical path lengths. This study investigates the correspondence between the travelled arterial length obtained from magnetic resonance imaging (MRI) images with commonly used body-surface distances obtained by tape measure.

Design and method: 98 healthy males/females were included (50% men, age 21–76). Exclusion criteria: heart disease, pacemaker, implant or clip, large tattoo, pregnant or breastfeeding, claustrophobia, significant obesity.

MRI path lengths were obtained through centrelines reconstructed from the centerpoints determined manually in each slice. The MRI-measured length (the arterial segment travelled in carotid-femoral PWV measurement) was compared to 7 tape measures commonly used in PWV measurement.

Results:

Conclusions: In the present population sample the distance (CA-FA) × 0.8, which is the distance from the carotid artery to the femoral artery multiplied by 0.8, provides the best approximation of the real travelled aortic path length.
