Is it true that a radioactive tracer will detect pathology in any body system?

Yes, a radioactive tracer can be used to detect pathology in various body systems, as it allows for imaging and functional assessment of organs and tissues. Different tracers are designed to target specific biological processes, enabling them to reveal abnormalities in areas such as the cardiovascular, neurological, and oncological systems. However, the effectiveness of detection depends on the specific type of pathology and the tracer used.
