| 摘要 |
The invention provides a method for imaging the distribution of n-acetylaspartic acid (NAA) in mammalian neuronal tissue, by a) exciting the neuronal tissue to generate magnetic resonance signals, including signals corresponding to NAA; b) suppressing non-NAA magnetic resonance signals by a combination of band selective inversion with gradient dephasing, and chemical shift selective pre-excitation; c) encoding a first spatial dimension of the NAA signal with readout encoding and a second spatial dimension of the NAA signal with gradient phase encoding, and d) using the encoded first and second spatial dimensions to image, by reconstrucion, the distribution of NAA in the tissue.
