MEGA-PRESS is the most widely used pulse sequence for edited MRS of low-concentration metabolites, e.g. GABA, glutathione and lactate. However, current implementations of MEGA-PRESS are diverse across MR vendors, leading to differences in the shape and intensity of the final edited signal. We demonstrate a new universal editing sequence (with MEGA and HERMES functionality) for the major MR vendor platforms with standardized RF pulse shapes, durations, amplitudes and sequence timings. Phantom and in vivo experiments show excellent agreement among vendors, including consistency in lineshape and reduced variation in concentration measurements.
