Quantification of pulsatile flow in MRI by an analysis of T2 changes in ECG-gated multiecho experiments.
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.
