PET是医学领域最先进的技术之一,它与普通的核医学显像一样,利用进入人体并参加体内生物活动的各种放射性示踪剂成像,但PET所用的是一种人造核素——正电子发射核素。目前在麻醉领域主要用于麻醉药(特别是异丙酚、异氟醚)对脑能量代谢方面的研究。 1 PET测定脑能量代谢的原理 研究大脑的能量代谢要用到一种被正电子标记的去氧葡萄糖如~(18)SFDG(~(18)F-flurodexyglucose),这种
PET, one of the most advanced in the field of medicine, uses the same radiotracer that enters the body and participates in the biological activities of the body, just like normal nuclear imaging, but PET uses an artificial nuclide - Positron Emission Nuclides. Currently in the field of anesthesia is mainly used for anesthetics (especially propofol, isoflurane) on brain energy metabolism research. 1 PET Determination of Brain Energy Metabolism: The study of brain energy metabolism uses a positively-labeled deoxyglucose such as ~ (18) SFDG (~ (18) F-flurodexyglucose)
