Rotating frame relaxation rates are measured during radiofrequency (RF) irradiation, and therefore can be altered by choosing different RF settings. The present work focuses on rotating frame relaxation methods based on adiabatic pulses, exploring how MR contrast can be created by using different pulse modulation functions, maximum amplitude or bandwidth of the adiabatic pulse. Results from theoretical simulations and animal MRS experiments are presented.
