Obstructive sleep apnea syndrome (OSAS) is a common
sleep disturbance affecting the adult population leading
to numerous health problems. Chronic intermittent
hypoxic episodes, hypercapnia and transient blood
pressure elevation in OSAS may damage neural structures
and induce cerebral metabolic changes. Even though many
structural imaging studies have shown brain tissue
changes in OSAS, only a limited number of MRS based
studies can be found so far. In this study, we
investigated neurochemical changes in multiple brain
regions of OSAS patients using compressed sensing (CS)
based Echo-planar J-resolved spectroscopic imaging (EP-JRESI)
and quantify the metabolites using prior knowledge
fitting (ProFit) algorithm.
