Figure 2c: Box plots showing systolic velocities measured with PW-DTI and TVI at four different sites at the aortic annulus. Boxplot is defined by median, quartiles (box), min-max (whiskers) and circle markers if outliers are present. (AA=aortic annulus, PW-DTI=pulsed wave tissue Doppler imaging, TVI=colour coded tissue Doppler imaging) (n=24).
