Answer:
Explanation:
82Rb (rubidium) is produced from a strontium-82 (82Sr)/82Rb generator, which can be eluted every 10 minutes.27 The T1/2 of 82Sr is 25.5 days, which results in a generator life of 6 to 8 weeks. The short T1/2 of 82Rb (76 seconds) allows repeated and sequential perfusion studies but requires rapid image acquisition shortly after tracer administration.3,12 82Rb is a monovalent cationic analog of potassium and has similar biological activity to thallium-201 (201Tl).
