Nuclear Medicine uses a special camera to take pictures of tissues and organs in the body.
Clients swallow, inhale, or are given a needle with a radiotracer before their exam. Radiotracers go to a specific body part so the camera can take pictures. (tests may take a number of hours to complete; patients may be required to return later that day or the next day to complete exam).
Radiotracers are also given to treat diseases like thyroid disease.
