At high field strengths, fast spin echo is a SAR constrained procedure; parameter concessions are required to enable its use. Typical modifications include elongated RF pulses and reduced refocusing angles. We present an SNR analysis investigating the effects of reduced angles (lower signal) and longer RF pulses (less readout time) and present a reliable method for rapidly selecting these parameters to optimize the SNR for a given target power level.
