## Abstract Existing magnetic resonance methods for diffusion imaging, including echo planar, are ineffective in the beating heart due to motion‐induced signal attenuation. To overcome this problem, we used a diffusion‐weighted stimulated echo‐echo planar magnetic resonance imaging sequence. The tw

## Abstract Diffusion MRI has the potential to probe the compartmental origins of MR signals acquired from human nervous tissue. However, current experiments in human subjects require long diffusion times, which may confound data interpretation due to the effects of compartmental exchange. To inves
The effect of possible susceptibility-induced gradients on measurements of water diffusion along the transverse and longitudinal axes of white matter fibers in the brain was investigated in vivo at 1.5 T. Measurements obtained with sequences sensitive and insensitive, respectively, to susceptibility
## Abstract The proton NMR transverse relaxation time __T__~2~ of glutamate (Glu) in human brain was measured by means of spectrally selective refocusing at 3.0 T in vivo. An 81.4‐ms‐long dual‐band Gaussian 180° RF pulse, designed for refocusing at 2.35 and 3.03 ppm, was employed within point‐resol
