rubidium-82 chloride

Rubidium-82 chloride is a **radiopharmaceutical diagnostic agent** primarily used in **Positron Emission Tomography (PET) imaging** of the myocardium, under rest or pharmacologic stress, to evaluate **regional myocardial perfusion** in adult patients with suspected or known **coronary artery disease**[1][2][3][5]. The compound consists of the radioactive isotope rubidium-82 (half-life 75 seconds), produced onsite from a strontium-82 generator and administered intravenously. Biologically, Rb-82 acts as a **potassium analog** due to its similar ionic radius, allowing it to be rapidly taken up by myocardial cells in proportion to blood flow, thus enabling perfusion imaging[2][4]. In areas of infarction or ischemia, reduced uptake provides diagnostic information about myocardial viability[1][2].
