KryptoScan (⁸¹Rb/^81mKr) generator

KryptoScan is a radionuclide generator. The mother radionuclide (Rubidium-81) is immobilized on a membrane, through which the daughter radionuclide (Krypton-81m) is eluted with the passing of air. Krypton-81m is ideally suited for lung ventilation studies. Its very short half-life results in a low radiation burden for the patient. With a gamma energy higher than that of ^99mTc, it enables lung ventilation studies to be performed immediately after a perfusion study of the pulmonary vascular bed.
