Previous studies have used PET to map changes in regional cerebral blood flow (rCBF) in response to hypoglycemia, but the spatial resolution of PET is typically low (8-10 mm). Higher resolution would be advantageous for localizing smaller structures involved in hypoglycemia detection and counterregulation. In this study, three-coil CASL was implemented and utilized on a 3 Tesla clinical scanner to determine if changes in rCBF detected at a resolution of 2 2 3 mm could be used to identify those regions that are activated in response to hypoglycemia.
