Computer-optimized decoupling scheme for wideband applications and low-level operation
Traditional modulation methods for broadband proton decoupling (1-4) have now been superseded by modern pulse techniques (5) using sequences of composite 180” pulses (6). Initial progress was… Expand

The purpose of this study is to describe the Gannet toolkit for the quantitative batch analysis of gamma‐aminobutyric acid (GABA) ‐edited MRS data.
Diffusion tensor imaging in children and adolescents: Reproducibility, hemispheric, and age-related differences
UNLABELLED We evaluated intra-rater, inter-rater, and between-scan reproducibility, hemispheric differences, and the effect of age on apparent diffusion coefficient (ADC) and fractional anisotropy… Expand
Multi-parametric neuroimaging reproducibility: A 3-T resource study
Modern MRI image processing methods have yielded quantitative, morphometric, functional, and structural assessments of the human brain. These analyses typically exploit carefully optimized protocols… Expand
Diffusion magnetic resonance imaging: Its principle and applications
Diffusion magnetic resonance imaging (MRI) is one of the most rapidly evolving techniques in the MRI field. This method exploits the random diffusional motion of water molecules, which has intriguing… Expand
MR imaging of human brain at 3.0 T: preliminary report on transverse relaxation rates and relation to estimated iron content.
PURPOSE To determine the transverse relaxation rates R2 and R2' from several gray matter regions and from frontal cortical white matter in healthy human brains in vivo and to determine the… Expand
Clinical proton MR spectroscopy in central nervous system disorders.
A large body of published work shows that proton (hydrogen 1 [(1)H]) magnetic resonance (MR) spectroscopy has evolved from a research tool into a clinical neuroimaging modality. Herein, the authors… Expand
Single‐voxel proton MRS of the human brain at 1.5T and 3.0T
Single‐voxel proton spectra of the human brain were recorded in five subjects at both 1.5T and 3.0T using the STEAM pulse sequence. Data acquisition parameters were closely matched between the two… Expand
