Four-dimensional flow magnetic resonance imaging (4D flow MRI) enables comprehensive access to time-varying and multidirectional blood flow through the cavities of the heart and great vessels. This presentation aims to assist understanding of acquisition and analysis methods of 4D flow MRI with a focus on the heart and greater vessels. Different visualization strategies and computation of derived flow parameters, as wall shear stress, pressure difference, turbulent kinetic energy, and intracardiac flow components, are discussed.
