## 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 __In vivo__ ^1^H spectroscopy using the STEAM sequence for localization has been applied to the human kidney in normal volunteers and subjects with succesful renal transplants. We show that, within the resolution of our measurements, trimethylamines are present in the spectra from some
## Abstract Localized proton spectroscopy of the brain was performed on MS patients (__n__ = 18) and the results are compared with those of a control group (__n__ = 17). The experiments were performed in a 1.5βT Siemens Magnetom using the stimulated echo method and selective water suppression. Acqu
## Abstract ## Purpose: To propose a strategy for reducing radiofrequency (RF) power deposition by stochastic proton decoupling based on Rayleigh's theorem. ## Materials and Methods: Rayleigh's theorem was used to remove frequency components of stochastic decoupling over the 3.90β6.83 ppm range.
A quadrature transmit/receive coil for proton-decoupled An ideal coil configuration for in vivo proton-decoupled NMR spectroscopy requires a highly sensitive 13 C coil as 13 C or 31 P spectroscopy half-volume applications, which retains optimal performance on the 1 H frequency, was built. well as an
