A rubidium-based myocardial perfusion imaging test is conducted with the Rubidium-82 radiotracer. The unique characteristics of Rb-82 provide certain advantages over testing with other isotopes.
The CardioGen-82 Generator
The CardioGen-82 closed-system generator produces the Rubidium-82 radiotracer used in a Rubidium PET scan in New York. The generator cart is self-contained with an accurate and automated dosage-measurement system. It also houses onboard waste storage, electronics support, and a lead line for a minimum of radiation exposure.
The BRACCO-certified CardioGen-82 generator is FDA-approved for cardiac PET imaging. It generates the isotope as needed, and the isotope is replaced after 28 days per US Nuclear Regulatory Commission regulations.
Rubidium Stress Tests
The positron-emitting Rubidium-82 radiotracer used in a Rubidium PET scan in New York has a 75-second physical half-life. The radiotracer’s 20mCi intravenous dose uptakes quickly in heart muscle and displays within a minute from the injection.
After a PET imaging system makes 3D images of the uptake, the patient receives a Lexiscan stress agent, followed by further imaging. A comparison of the two imaging sessions helps physicians understand the location, extent, and severity of any impeded blood flow toward the heart muscle.
The Advantages of Rubidium-82
Rubidium-82’s short half-life makes it the foremost diagnostic tool for nuclear cardiology. The result is a 25 to 35-minute scan time and a minimum of radiation exposure for the patient. It is available at any time. Its imaging quality allows for improved diagnostic accuracy, even during peak stress, and it represents reduced radiation exposure for staff.
