## Abstract A method to achieve simultaneous water and lipid suppression is described. The key feature of the new dual suppression technique is the use of the wellβknown hyperbolic secant (HS) waveform as a 90Β° saturation pulse. Two HS pulses with opposite frequency offsets are employed either sequ
## Abstract An experimental method is described to eliminate frequency modulation sidebands in localized in vivo proton MR spectra acquired without water suppression. Based on the fact that the phases of the sideband artifact signals are coherent with the phases of the gradient pulses, the proposed
## Abstract A new twoβscan method for localized ^1^H in vivo NMR spectroscopy (MRS) without water suppression (WS) is described. In one of the scans, two chemical shift selective 180Β° pulses are applied prior to a standard localization sequence to invert all metabolite signals upfield and downfield
