ABSTRACT:
To prepare magnetization for steady state magnetic resonance imaging, magnetic resonance is primed using a parameterized priming sequence (60). The parameterized priming sequence (60) has a spectral offset parameter value (40) corresponding to a spectral offset of the steady state imaging. Subsequent to the priming, steady state magnetic resonance imaging data at the first spectral offset is acquired using a magnetic resonance imaging scanner (10). A reconstruction processor (44) reconstructs the imaging data to generate an image representation. Preferably, the parameterized priming sequence (60) includes a longitudinal priming sequence (62) that prepares longitudinal magnetization in a state approximating a steady state longitudinal magnetization. A spoiler sequence (64) spoils transverse magnetization while retaining longitudinal magnetization. A transverse priming sequence (66) prepares traverse magnetization in a state approximating a steady state transverse magnetization.
