Synopsis

Keywords: Quantitative Imaging, Heart, 2D FlowVarious confounders can have an influence on the results of cardiovascular MRI (CMR) examinations. Data about systematic investigations of such confounders are sparse. 2D Flow CMR using segmented and realtime measurements was performed in 20 healthy travelling volunteers to examine the influence of beat-to-beat variability between different heart cycles, sequence types, field strengths and scanner configurations as well as examiners on forward flow volume and peak velocity and compared to 95% tolerance intervals established by intraobserver analysis to test for comparability and precision of measurements which revealed good to very good comparability regarding various physiological, technical and post- processing confounders.
