In a noninvasive and non-radioactive manner, magnetic resonance spectroscopy can quantitatively analyze in vivo abnormalities of biochemical metabolism within brain tissue.
Compared with 3.0T magnetic resonance spectroscopy, high-field magnetic resonance spectroscopy (≥ 7.0T) exhibits high spatial resolution and density resolution, microscopic imaging of the living body, and obtains both high scanning resolution and result precision within a shorter scan time, thus providing a higher value in clinical diagnosis.
In a recent study reported in the Neural Regeneration Research (Vol. 9, No. 4, 2014), 7.0T magnetic resonance spectroscopy showed that in the hippocampus of Alzheimer's disease rats, the N-acetylaspartate wave crest was reduced, and the creatine and choline wave crest was elevated. This finding was further supported by hematoxylin-eosin staining, which showed a loss of hippocampal neurons and more glial cells.
