Abstract

Magnetic resonance imaging ('MRI') systems and methods for acquiring multi-slice gradient echo images having a substantially constant T1-weighting including selecting a first scan having a desired contrast associated with T1-weighting and, given a first repetition time, TR1, and a first flip angle, flip1, associated with the first scan, selecting an effective repetition time, TReff, that provides the desired contrast. The MRI systems and methods also including holding the effective repetition time, TReff, substantially constant in relation to a second scan. The MRI systems and methods further including, given a second repetition time, TR2, determining a second flip angle, flip2, and, given the second flip angle, flip2, determining the second repetition time, TR2. The MRI systems and methods still further including performing the second scan using the second repetition time, TR2, and the second flip angle, flip2, and maximizing a signal-to-noise ratio, S/N, of the second scan.
