To clarify whether the content of glutathione (GSH) in the brain can be estimated by the uptake of 99mTc-meso-HMPAO, we conducted the following in vivo and in vitro experiments. ⋯ GSH may have a major responsibility for trapping 99mTc-HMPAO in the brain, suggesting the possibility of in vivo measurement of brain GSH with 99mTc-meso-HMPAO.
