Fig. 6From: Flow measurement at the aortic root - impact of location of through-plane phase contrast velocity mappingBland-Altman plots of interobserver variability. The continuous line represents the mean (bias) and the dotted lines represent the 95 % limits of agreement for a Stroke volume measured with flow at valve level b Stroke volume measured with flow at the sinotubular junction. Bland-Altman analyses showed no proportional bias (valve p = 0.35, ST p = 0.44). SV stroke volume, mL millilitersBack to article page
