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.
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.
四维血流心脏磁共振成像(CMR)能够全面评估心脏心室的血流动能。与标准二维图像采集相比,四维血流CMR被认为具有更高的可重复性,这在可能需要重复检查时非常重要。目的是评估在英国和荷兰的两个中心对20名健康志愿者使用左心室四维血流评估血流动能时观察者间和观察者内的可重复性。
该数据集包含20名无已知心血管疾病的健康志愿者的四维血流CMR血流动能数据。呈现的是整个心动周期(整体)、收缩期和舒张期成分的动能数据,以及舒张早期和晚期充盈的血流动能数据。此数据可供重复使用,对于支持其他研究具有重要价值,例如可以用于更大样本量且具有更强统计效力的研究,以便进一步分析这些变量。
