A technique for the handling and dispensing of Xe-127: concise communication.

Xenon-127, which provides photon energies better suited to the Anger camera and reduces radiation dosage to the patient compared with Xe-133, has become commercially available from Brookhaven Laboratories. Its higher cost and longer shelf-life require improved handling and dispensing of shipment ampoules containing gas of high specific activity. The technique described permits individual doses to be prepared for gaseous administration, or dissolved in saline for i.v. injection.
