Rubidium-82 (82 Rb) is a radioactive isotope of rubidium. 82 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.
Rubidium-82 chloride is a form of rubidium chloride containing a radioactive isotope of rubidium. It is marketed under the brand name Cardiogen-82 by Bracco Diagnostics for use in Myocardial perfusion imaging . [ 1 ]
Cardiac PET (or cardiac positron emission tomography) is a form of diagnostic imaging in which the presence of heart disease is evaluated using a PET scanner. Intravenous injection of a radiotracer is performed as part of the scan. Commonly used radiotracers are Rubidium-82, Nitrogen-13 ammonia and Oxygen-15 water. [1]
Other than 87 Rb, the longest-lived radioisotopes are 83 Rb with a half-life of 86.2 days, 84 Rb with a half-life of 33.1 days, and 86 Rb with a half-life of 18.642 days. All other radioisotopes have half-lives less than a day. 82 Rb is used in some cardiac positron emission tomography scans to assess myocardial perfusion. It has a half-life of ...

Although rubidium is monoisotopic, rubidium in the Earth's crust is composed of two isotopes: the stable 85 Rb (72.2%) and the radioactive 87 Rb (27.8%). [23] Natural rubidium is radioactive, with specific activity of about 670 Bq /g, enough to significantly expose a photographic film in 110 days.
Flotufolastat (18 F), sold under the brand name Posluma, is a radioactive diagnostic agent for use with positron emission tomography (PET) imaging for prostate cancer. [1] The active ingredient is flotufolastat ( 18 F).
