Proton MR spectroscopy (MRS) studies have found both decreased N-acetylaspartate (NAA)
and increased myo-inositol in the occipital, temporal, parietal, and frontal regions of patients …

Anatomic and functional neuroimaging with magnetic resonance imaging (MRI) includes the
technology more widely known as magnetic resonance spectroscopy (MRS). Now a routine …

Neuroimaging methods can be used to investigate whether sleep disorders are associated
with specific changes in brain structure or regional activity. However, it is still unclear how …

In vivo magnetic resonance spectroscopy (MRS) addresses metabolic pathways and their
steady states in different tissue types. The brain has by tradition, and due to technical …
