摘要：

Molecular self-diffusion coefficients of water (0.75 +/- 0.05), N-acetylaspartate (0.27 +/- 0.04), creatines (0.27 +/- 0.04), and cholines (0.28 +/- 0.08) x 10(-5) cm2 S-1 were obtained from localized proton NMR spectra of rat brain in vivo using diffusion-weighted stimulated-echo (STEAM) sequences with a diffusion time of (DELTA - delta/3) = 17 ms.
