Intra- and interobserver agreement of 4D flow CMR-derived flow rate and velocity measurements. A, B Bland–Altman plots of intraobserver agreement (0.9 ± 5.9%) and interobserver agreement (0.2 ± 6.4%) for measurements of flow rates within the covered part of the TIPS stent graft (TIPSp, TIPSm, and TIPSv) at velocity encoding of 2 m/s. C, D Bland–Altman plots of intraobserver agreement (0.4 ± 1.6%) and interobserver agreement (0.5 ± 1.5%) for measurements of flow velocities within the covered part of the TIPS stent graft at velocity encoding of 2 m/s. Middle solid line indicates mean bias of flow rate and flow velocity measurements. Dashed lines indicate limits of agreement
