4D flow CMR demonstrates excellent inter- and intra-observer reproducibility for assessing left ventricular blood flow kinetic energy in healthy volunteers.
Supports research applications of 4D flow CMR; leaves open clinical adoption pending validation in patients.
OBJECTIVES: Four-dimensional flow CMR allows for a comprehensive assessment of the blood flow kinetic energy of the ventricles of the heart. In comparison to standard two-dimensional image acquisition, 4D flow CMR is felt to offer superior reproducibility, which is important when repeated examinations may be required. The objective was to evaluate the inter-observer and intra-observer reproducibility of blood flow kinetic energy assessment using 4D flow of the left ventricle in 20 healthy volunteers across two centres in the United Kingdom and the Netherlands. DATA DESCRIPTION: This dataset contains 4D flow CMR blood flow kinetic energy data for 20 healthy volunteers with no known cardiovascular disease. Presented is kinetic energy data for the entire cardiac cycle (global), the systolic and diastolic components, in addition to blood flow kinetic energy for both early and late diastolic filling. This data is available for reuse and would be valuable in supporting other research, such as allowing for larger sample sizes with more statistical power for further analysis of these variables.

Grafton‐Clarke et al. (2021) conducted an observational in Healthy volunteers (n=20). Four-dimensional flow CMR was evaluated on Inter-observer and intra-observer reproducibility of blood flow kinetic energy. Four-dimensional flow CMR demonstrated excellent concordance in global kinetic energy parameters for both inter-observer and intra-observer reproducibility analyses in healthy volunteers.
