Reproducibility of Left Ventricular Blood Flow Kinetic Energy Measured by Four-Dimensional Flow CMR

Reproducibility in cardiac MRI research is a pervasive issue across the field, which impacts the translational pathway. Given the relative infancy of research within 4D-flow cardiovascular magnetic resonance (CMR) imaging and the accepted potential for this imaging technique to propel our understanding of cardiovascular disease, it becomes important to establish repeatability of the various aspects of the techniques. This dataset includes the left ventricular blood flow kinetic energy parameters of twenty patients void of any known cardiovascular disease, collected from two sites in the United Kingdom and the Netherlands. Here we present data from the inter-observer and intra-observer reproducibility analyses following 4D-flow CMR.
