1. In a method for producing a set of magnetic resonance three-dimensional image data, a preparation-acquisition-recovery pulse sequence cycle comprising the steps of:

  • a--a magnetization preparation period in which a series of at least one of RF pulses, gradient field pulses, and time delays are applied to encode the desired contrast properties in the form of longitudinal magnetization,b--a data acquisition period, said data acquisition period including at least two repetitions of a gradient echo sequence to acquire data for a fraction of k-space,c--a magnetization recovery period which allows T1 and T2 relaxation before the start of the next sequence cycle, andd--repeating steps a, b and c until a predetermined k-space volume is sampled.
