A previously developed magnetic resonance spectroscopy method is improved upon which is now able to obtain spectra with an echo time as short as 4 ms, while recovering the entirety of the available magnetization. This method obtains full 3D spatial localization through a 2D adiabatic inversion pulse which is cycled “on” and “off” every other repetition, in combination with a slice-selective excitation pulse. Both 1D and 2D spectra with an ultrashort echo time of 4 ms are demonstrated at 3T. High quality spectra were obtained for all experiments.
