Highlights • With 4D flow, any plane of interest can be interactively chosen for quantitative measurements. • Anatomical and flow data is obtained during an approximately 10-minute free-breathing scan. • 4D CMR flow measurements correlated well with the 2D PC ones. • Eddy current correction is important for good results with 4D flow
