Measuring Brain Serine With Proton Magnetic Resonance Spectroscopy At 3.0 Tesla, Homa Javadzadeh Dec 2016

Measuring Brain Serine With Proton Magnetic Resonance Spectroscopy At 3.0 Tesla, Homa Javadzadeh

Electronic Thesis and Dissertation Repository

Proton magnetic resonance spectroscopy (MRS) non-invasively measures regional human brain chemistry in vivo, providing concentration estimates for several metabolites in a pre-selected region of interest. MRS has been applied to investigations of disease-related metabolic and neurochemical alterations in schizophrenia since the early 90’s.

The objective of this research is to implement a metabolite-selective MRS method to quantify endogenous concentrations of human brain serine. Serine is a naturally-occurring amino acid and an important co-modulator of the N-Methyl D-aspartic Acid (NMDA) glutamate receptor. Glutamate abnormalities have been implicated in the pathophysiology of schizophrenia, especially its so-called negative and cognitive symptoms, which can …
