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.[1] 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.[2] The half-life of the rubidium-82 is only 1.27 minutes; it is normally produced at the place of use by rubidium generators.[3]
