Kr-81m for determination of right ventricular ejection fraction (RVEF)


A 10–12 mCi 81Rb→81mKr generator was connected to a specially designed short-period infusion set, to produce an equilibrium activity distribution in the right heart. This procedure was tested in 25 individuals to calculate the right ventricular ejection fraction (RVEF). On average 30 heart cycles were analyzed per study. No background activity from the left… (More)
