This study addresses the pressing need for non-invasive, continuous monitoring of cerebral physiologic derangements following traumatic brain injury (TBI). We combine frequency-domain and broadband diffuse optical spectroscopy with diffuse correlation spectroscopy to monitor cerebral oxygen metabolism, cerebral blood volume, and cerebral water content in an established adult swine-model of focal TBI. Cerebral physiology is monitored before and after TBI (up to 14 days post injury). Overall, our results suggest that non-invasive optics can monitor cerebral physiology impairments such as reduced oxygen metabolism, hemorrhage, and edema formation post-TBI.
