This thesis employed quantitative fMRI to investigate uncharted measures of MS cerebral physiology, which can contribute to the development of new MS biomarkers; specifically, motor cortex flow-metabolism coupling and global grey matter cerebrovascular reactivity (CVR) were quantified. Data analysis of 12 MS patients and 11 healthy controls revealed between-group differences in cerebral blood flow (CBF) and oxygen metabolism. However, the ratio between CBF and oxygen metabolism, as well as CVR, had no significant between-group differences. These findings provide preliminary information about MS pathology and potential MS biomarkers. This research also demonstrates limitations of quantitative fMRI that impede the ability to make robust conclusions; therefore, further methodological research is needed.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
