What are the benefits of using Rb-82 PET imaging over technetium?
Dorbala: 1. Availability round the clock (no need to order a dose). 2. Quick imaging protocols (seven minutes per scan). 3. Excellent image quality even in obese individuals. 4. Reduced occupational radiation exposure to staff. 5. Ability to image peak stress left ventricular function. Heller: 1. Higher image quality and efficiency. 2. It takes two-four hours to do SPECT studies while it takes 20-30 minutes to perform a PET study. 3. Higher diagnostic accuracy. What are the drawbacks of using Rb-82 PET? Dorbala: 1. High cost of the generator is the primary concern. 2. We may have limited imaging on patients that are extremely obese or greater than 400 lbs (especially at the end of generator life). 3. We do not have the option of reimaging patients as with Tc-99m radiotracers. Heller: 1. The tracer is supplied on a monthly basis and a volume of three patients a day is required to make it economically feasible. 2. One cannot perform exercises or form a stress and right now it’s limited t
