Scintigraphy is a diagnostic imaging technique that uses radioactive tracers to create images of different organs and tissues in the body. It is commonly used to detect abnormalities or diseases by measuring the distribution and function of the tracer within the body. Scintigraphy can provide important information about the structure and function of various organs, such as the heart, lungs, thyroid, and bone. This imaging technique is non-invasive and can help doctors diagnose and monitor a wide range of medical conditions.
