## Abstract The flip angle which maximizes contrast between materials with different __T__~1~can be caculatd from the root of a cubic expression. A simple closed form expression can be used if contrast is defined in a differential sense and results in only slight contrast loss even with large __T__

## Abstract In spoiled gradient echo sequences, the __T__~1~‐weighting of image contrast is strongly affected by a nonlinear interaction of two sequence parameters, repetition time (TR) and flip angle (Ξ±). If Ξ± is not properly adjusted to compensate for variation in TR due to changing resolution, b

Theoretical expressions of flip angle values maximizing signal [a x -TE/2-b y -TE/2-echo-(TR-TE) -], [1] intensity and T 1 -dependent contrast are derived for spin-echo and inversion-recovery sequences. Experimental data and theoretical where a and b are respectively the nutating and refocusing pred
