摘要:
To enable improved magnetic resonance imaging in the vicinity of an interference object that produces a magnetic interference field in an examination region, in a method and apparatus for magnetic resonance imaging of the examination region magnetic resonance raw data are acquired from the examination region by execution of a magnetic resonance sequence having multiple repetition intervals and refocusing of spins in the examination region at the end of each repetition interval repetition intervals. During at least part of the duration of the acquisition of the magnetic resonance raw data, a magnetic compensation gradient is activated that is opposed to the magnetic interference field.
