Abstract
In a method for switching a localized saturation pulse in magnetic resonance spectroscopy or magnetic resonance imaging, magnetic field gradients are switched during the saturation pulse, with the steps of establishing the examination region, establishing the position of the saturation pulse relative to the examination region, determining the spectral position of the signal to be saturated, and selecting the magnetic field gradients dependent on the position of the saturation pulse relative to the examination region and dependent on the spectral position of the signal to be saturated.
Claims5
A method for generating a localized saturation pulse in magnetic resonance spectroscopy or magnetic resonance imaging, comprising the steps of:
- defining an examination region from which magnetic resonance signals are to be acquired;
- establishing a position of a saturation pulse relative to said examination region;
- determining a spectral position of an MR signal, from said examination region, that is to be saturated;
- configuring a magnetic field gradient dependent on the position of the saturation pulse relative to the examination region and dependent on the spectral position of the MR signal to be saturated;
- and
- activating said magnetic field gradient in said examination region.
