Robust selective signal suppression using binomial off‐resonant rectangular (BORR) pulses

PURPOSE: To study the selective signal suppression capability of a binomial off-resonant rectangular (BORR) radiofrequency pulse method. MATERIALS AND METHODS: The BORR pulse consists of two consecutive rectangular pulses with a phase difference of π. The exact solution of the Bloch equations was used to simulate its frequency response. The BORR pulse was implemented in a gradient echo sequence and tested on phantoms, the knee, and the breast.
