Table 5 Reproducibility. Three mice were measured twice within 7 days. Longitudinal WSS, circumferential WSS and radial stress as well as OSI values were determined in 3 regions (ascending, bifurcation area, descending) and 4 sections, respectively. Correlation coefficient r2 (between measurement 1 and 2), bias (mean of difference between measurement 1 and 2) and scattering (1.96 SD of difference between measurement 1 and 2) were determined for all 4 measured variables. The corresponding plots can be found in Additional file 1: Figure S1–S3
