The purpose of the present study was to evaluate
different methods for extracting pulse wave velocity (PWV)
from 4D MR velocity data. 6 different methods were
implemented and were applied to estimate aortic PWV in 8
young and 8 older normal volunteers. All methods were
capable of resolving age-related differences in aortic
PWV. However, systematic and significant differences
were observed between the methods. These findings
indicate that care must be taken when interpreting PWV
estimates obtained by different types of methods.
