Cerebral blood flow and metabolism estimated by brain temperature using ultra-high field magnetic resonance imaging in patients with carbon monoxide poisoning

Abstract

Brain temperature (BT) elevation indicated misery perfusion that cerebral blood flow decreased and cerebral metabolic ration of oxygen (CMRO₂) was maintained in patients with chronic ischemia. In the previous work, it has been reported that carbon monoxide (CO) poisoning also caused abnormal cerebral perfusion and metabolism like misery perfusion. Thus, BT may be also associated with states of the abnormal cerebral perfusion and metabolism in patients with CO poisoning. Here, we investigated that CO poisoning was associated with BT change in the patients.
