Description
Sources: https://www.drugs.com/pro/neurolite.html

Bicisate hydrochloride is a ligand that is used to form a complex with technetium. Tc99m Bicisate forms a stable, lipophilic complex that crosses intact cell membranes and blood brain barrier by passive diffusion. The amount of tc99m bicisate is stable in the brain until about 6 hours. Tc99m bicisate is indicated as an adjunct to conventional CT or MRI imaging in the localization of stroke in patients in whom stroke has already been diagnosed.
