✦ Synopsis

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~1~ differences.

## 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 (α). If α is not properly adjusted to compensate for variation in TR due to changing resolution, b
