U.S., Aug. 6 -- ClinicalTrials.gov registry received information related to the study (NCT07103616) titled 'Individual Cerebral Hemodynamic Oxygenation Relationships - ICHOR 4' on July 29.

Brief Summary: The goal of this clinical trial is to understand whether there are differences in the cerebral blood flow, and oxygen metabolism affected by two types of anesthesia: Propofol or Dexmedetomidine. Subjects who require clinical anesthesia for a clinical MRI and for whom the use of Propofol and Dexmedetomidine are in clinical equipoise will be offered to have the anesthesia they will receive during their MRI randomized.

* Change in cerebral blood flow (ml blood/100g/min)

* Change in cerebral metabolic rate of oxygen (ml O2/100g/min)
