## Abstract The results published in the article __Gradient‐Induced Acoustic and Magnetic Field Fluctuations in a 4T Whole‐Body MR Imager__ by Wu et al. (Magn Reson Med 2000;44:532–536) appear to be consistent with the response of a time‐stationary linear system. Since a linear system is more simpl

## Abstract Signals from intermolecular double‐quantum coherences (iDQCs) have been shown to be insensitive to macroscopic field inhomogeneities and thus enable acquisition of high‐ resolution MR spectroscopy in the presence of large inhomogeneous fields. In this paper, localized iDQC ^1^H spectros
## Abstract ## Purpose To improve signal‐to‐noise ratio (SNR) of intermolecular double‐quantum coherence (iDQC) MRS on a 3 Tesla (T) whole‐body scanner. ## Materials and Methods A 32‐channel phased array coil was used to acquire iDQC signal of a MRS phantom in the presence of large field inhomog
