Question

Quizplus · Accepted Answer

Both 13N-ammonia and 82Rb chloride are PET perfusion tracers commonly used to determine whether certain areas of the heart are receiving sufficient blood flow (perfusion). 13N-ammonia is preferred in some centers as it has a shorter half-life than 82Rb chloride and is therefore associated with a lower radiation dose to patients and staff. However, 82Rb chloride is more widely used due to its longer half-life and wider availability.
