Xenon-Enhanced Cerebral Blood Flow at 28 Xenon Provides Uniquely Safe Access to Quantitative Clinically Useful Cerebral Blood Flow Information: A Multicenter Study

摘要

Xe-CT measures CBF and can be used to make clinical treatment decisions. Availability has been limited, in part due to safety concerns. Due to improvements in CT technology, the concentration of inhaled xenon gas has been decreased from 32% to 28%. To our knowledge, no data exist regarding the safety profile of this concentration. We sought to better determine the safety profile of this lower concentration through a multicenter evaluation of adverse events reported by all centers currently performing xenon/CT studies in the US.
