摘要:
A method a for acquiring magnetic resonance data of an object under examination by means of a magnetic resonance system comprises: in an excitation phase, applying an RF excitation pulse; in a wait phase following the excitation phase, applying at least one first RF refocusing pulse after the applied RF excitation pulse according to a first echo spacing; in an acquisition phase following the wait phase, applying at least two further RF refocusing pulses to generate echo signals according to a second echo spacing, wherein the second echo spacing is smaller than the first echo spacing; and reading out the echo signals generated in the acquisition phase as magnetic resonance data from which image data can be reconstructed, wherein in the wait phase at least two spoiler gradients are switched in the readout direction.
