Generators designed to produce rubidium 82 chloride (RbCl) solutions for intravenous administration. These generators typically consist of a lead-shielded column containing strontium (Sr) 82 (usually obtained from a particle accelerator) adsorbed on stannic oxide; the generator provides a sterile solution (eluate) of radioactive rubidium 82 obtained from the Sr 82. Radioactive rubidium 82 injection is used for imaging of the myocardium and/or to evaluate myocardial perfusion using positron emission tomography (PET) in patients with suspected or existing coronary artery disease or myocardial infarction.
