Rubidium-82 chloride

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. It is rapidly taken up by heart muscle cells, and therefore can be used to identify regions of heart muscle that are receiving poor blood flow in a technique called PET perfusion imaging. The half-life of rubidium-82 is only 1.27 minutes; it is normally produced at the place of use by rubidium generators.
