1. What is Nuclear Medicine?
Nuclear medicine is a type of medical way to see diseases using radioactive metals. The machinery is harmless to the patient and unable to penetrate through the skin tissues. It is used with x-rays that use radioactive material called radio pharmaceutical or radio tracer, which then goes into the bloodstream, swallowed, or inhaled with a gas. This radioactive stuff starts to build up where the doctor wants to see the disease, where it gives off a tiny-like type of ray called gamma rays. Cameras find this energy and creates an image on the other computers which the doctors look at.
