摘要
Disclosed is a method of obtaining magnetic resonance signals from a body which are spatially and spectrally selective comprising the steps of applying a static magnetic field (Bo) to said body thereby aligning nuclear spins, applying a modulated magnetic gradient (G(t)) to said body, applying an RF excitation pulse (B(t)) to said body to tip said nuclear spins, said RF excitation pulse being related to said modulated magnetic gradient whereby resulting magnetic resonance signals are spatially and spectrally dependent, and detecting said magnetic resonance signals. The steps can be repeated in a multi-slice or multi- spectral acquisition mode. The steps can be repeated in a rapid gradient echo pulse sequence.
