Abstract
In a spectroscopic imaging method for a magnetic resonance apparatus, an excitation radio-frequency pulse having a flip angle of approximately 90° is emitted, followed by transmission of a rephasing radio-frequency pulse having a flip angle of 180°, activation of a phase-coding gradient, and activation of a readout gradient and acquisition of a magnetic resonance signal. The following steps are then executed at least three times. A rephasing radio-frequency pulse having a flip angle of 180° and having a 90° phase offset in relation to a chronologically immediately preceding rephasing radio-frequency pulse is emitted, and the readout gradient is activated and a magnetic resonance signal is acquired.

A spectroscopic imaging method for a magnetic resonance apparatus, comprising the steps of:
- (a) emitting an excitation radio-frequency pulse having a flip angle of approximately 90°;
- (b) emitting a rephasing radio-frequency pulse having a flip angle of 180°, and activating a phase-coding gradient, and activating a readout gradient and acquiring a magnetic resonance signal;
- and
- (c) at least three times, emitting a rephasing radio-frequency pulse having a flip angle of 180° and a 90° phase offset relative to a chronologically immediately preceding rephasing radio-frequency pulse, activating said readout gradient and acquiring a magnetic resonance signal.
