Abstract
Methods, and systems and apparatus for implementing the methods, are described for performing efficient multispectral magnetic resonance imaging, such that images of multiple contrast weightings for each slice are acquired in a single scan. Such differentially weighted MR images are thus suitable for generating a plurality of coregistered parameter maps for each slice. The methods may comprise applying a first excitation pulse to a first slice of a subject; detecting a first plurality of echo signals emitted by the first slice after the first excitation pulse; waiting a first period of time; applying a second excitation pulse to the first slice during partial recovery of a longitudinal magnetization of the first slice; and detecting a second plurality of echo signals emitted by the first slice after the second excitation pulse.
