Fast self-navigated wall shear stress measurements in the murine aortic arch using radial 4D-phase contrast cardiovascular magnetic resonance at 17.6 T

Table 4 Peak longitudinal, circumferential and radial stress and oscillatory shear index (OSI) for all 14 analysis planes (see Fig. 4B). All data are presented as average values over all 7 wild-type mice
