Rubidium-82
Rubidium-82 (Rb) is a radioactiveisotope of rubidium. Rb is widely used in myocardial perfusion imaging. This isotope undergoes rapid uptake by myocardiocytes, which makes it a valuable tool for identifying myocardial ischemia in Positron Emission Tomography (PET) imaging. Rb is used in the pharmaceutical industry and is marketed as rubidium-82 chloride under the trade names RUBY-FILL and CardioGen-82.
