Xenon/CT cerebral blood flow (CBF) analysis has been utilized in the evaluation of 35 patients sustaining severe cranial trauma. The patient population included closed head injury, focal hematoma, and the sequelae of trauma including coma, persistent alteration of consciousness, and brain death. Xe/CT CBF analysis has proven helpful in the determination of appropriate degrees of hyperventilation therapy for the head injured patient. The technique is helpful for determining both local and remote changes of CBF as an aid in deciding upon surgical intervention. Severely decreased flows, compatible with brain death, can be demonstrated. The technique shows promise in the evaluation of physiologic changes accompanying therapy for the injured brain.
氙/CT脑血流量（CBF）分析已用于评估35例严重颅脑外伤患者。患者群体包括闭合性颅脑损伤、局灶性血肿以及创伤后遗症，如昏迷、意识持续改变和脑死亡。氙/CT脑血流量分析已被证明有助于确定颅脑损伤患者的适度过度通气治疗程度。该技术有助于确定局部和远处的脑血流量变化，以辅助决定手术干预。可以显示与脑死亡相符的严重血流减少。该技术在评估受伤大脑治疗过程中的生理变化方面显示出前景。
