Featured are methods for magnetic resonance imaging in which MR signals of
selected tissues, fluid or body components in a target area are desired
to be essentially eliminated, which method includes applying an initial
RF inversion pulse to invert the magnetization of the selected tissues or
to apply any other T1 preparation aimed at nulling one or more tissue
species and successively applying one or more RF inversions pulses
thereafter. More particularly, the successively applied RF inversion
pulses are applied so as to essentially maintain the magnetization of the
selected tissues at or about the zero-crossing point of the longitudinal
magnetization. Such methods further include interleaving a plurality of
excitation pulses for acquiring image data and the RF inversion pulses so
that at least one of the plurality of excitation pulses follows in a time
sequence the application of one of the applied RF inversion pulses such
that the image data is acquired following an inversion pulse.
