Figure 2

Relative unsigned difference (RUD) in aortic arch pulse wave velocity from velocity-encoded MRI after temporal downsampling, with respect to PWV-assessment with maximal temporal resolution (PWVref). Downsampling (50% [Tres = 10 ms], 67% [Tres = 15 ms], 75% [Tres = 20 ms], and 80% [Tres = 25 ms]) was first achieved by repeated reconstruction of the original acquired MRI data for PWVref. Also downsampling was achieved by data removal as well as by data averaging from the reference PWV data set. Finally, downsampling was achieved by repeated scanning. Error bars represent standard deviation in RUD.
