Nuclear Medicine plays an important role in the diagnosis and treatment of disease. Nuclear medicine procedures are helpful to a broad range of medical specialties, from pediatrics to cardiology to oncology. There are nearly one hundred different nuclear medicine imaging procedures available.
What Is Nuclear Medicine?
Nuclear medicine is a diagnostic service that uses very small amounts of radioactive materials or radiopharmaceuticals to diagnose and treat disease. Radiopharmaceuticals are substances that travel to specific organs, bones, or tissues. The radiopharmaceuticals used in nuclear medicine emit gamma rays that can be detected externally by special types of cameras (gamma cameras or Positron emission tomography (PET) cameras). These cameras work in conjunction with computers to form images that provide information about the function of the organ being imaged. The amount of radiation from a nuclear medicine procedure is very low and can be comparable to that received during a diagnostic x-ray. The radioactive materials used have very short half-lives, which means that they decay rapidly and are no longer considered radioactive.
Location of Nuclear Medicine
The Nuclear Medicine Department at St. Mary’s is located on the first floor of the hospital. When you arrive at the hospital, please stop at the information desk for directions and a volunteer will be happy to escort you.
The Nuclear Medicine Department at Grand River Hospital is located on the 2nd floor next to Medical Imaging.
