Scatter plots of the correlation between flow volumes and mean flow velocity measured with the 4D flow GRAPPA2 and k-t-GRAPPA5 sequences and the 2D flow sequence (reference) in pulsatile flow. a, c Flow volume [L/min]. b, d Mean flow velocity [cm/s]. 2D, two-dimensional; 4D, four-dimensional; cm/s, centimetres per second; GRAPPA, generalised autocalibrating partially parallel acquisition; L/min, litres per minute
