The magnetic resonance (MR) signal from the hydrogen nuclei of blood is not only determined by the MR parameters T1, T2 and proton density, but is strongly dependent on the movement of the protons. Magnetic resonance imaging (MRI) offers therefore the possibility to visualize the distribution of moving spins, especially blood flow, noninvasively and without(More)
The transport of magnetization by fluid flow through thin slices in MRI causes changes in the measured T2 relaxation time. This effect is used to compute velocity values at several different times relative to the cardiac cycle using data in ECG-gated multiecho experiments which last a few minutes.
