Radiotracer

A radiotracer is a special substance containing a small amount of radioactive material, which emits detectable radiation. It is used in medical imaging to track processes within the body, such as blood flow or organ function. When introduced into the body, the radiotracer travels to specific tissues or organs, and a special camera detects the radiation it emits. This allows doctors to visualize and study internal structures and functions non-invasively, aiding in diagnosing or monitoring various health conditions accurately.
