Nuclear radiology is a subspecialty of radiology that involves the use of radioactive drugs to diagnose and treat diseases.
These radioactive materials are usually injected into a vein, but sometimes they may be swallowed or inhaled.Then, a gamma camera (a radio-sensitive receptor) tracks the movement of the radioactive material from outside the body by detecting the gamma rays emitted by the drug.
Depending on the type of imaging, 2D or 3D images of the body are created.
These radioactive drugs can also be used to treat some diseases such as hyperthyroidism, thyroid cancer, solid tumors, and bone metastases.
