What is the term used for the introduction of radioactive materials into the body for imaging?

The term used for the introduction of radioactive materials into the body for imaging is best captured by the concept of "planar nuclear medicine imaging." This type of imaging involves the administration of a radiopharmaceutical to the patient, which emits gamma rays that can be detected by specialized cameras. The resulting images provide valuable insights into the function of organs and tissues, allowing healthcare providers to diagnose and manage various medical conditions.

This process is distinct from other imaging techniques like nuclear imaging, which is a broader term encompassing all forms of imaging using radioactive substances, not just planar methods. Radiographic imaging refers specifically to the use of X-rays to create images, and tomography denotes imaging techniques that provide cross-sectional views, often contrasting with the planar approach used in nuclear medicine. Thus, "planar nuclear medicine imaging" accurately describes the specific method involving the introduction of radioactive materials for diagnostic imaging.
