nuclear medicine

What is Nuclear Medicine? 

Nuclear medicine uses radioactive isotopes to picture or photograph organs of the body to safely and effectively determine if an organ is functioning properly. Nuclear imaging is often used to view the structure of the main organs and tissues such as:

  • Brain
  • Heart
  • Kidneys
  • Liver
  • Lungs
  • Thyroid
  • Bone 

When is Nuclear Medicine Used?

Nuclear medicine images can assist physicians in analyzing blood flow and diagnosing diseases. Tumors, infection, and other disorders can be detected by evaluating organ and cardiac function.

Nuclear Medicine is unique because it provides doctors with information about both structure and function. Nuclear medicine specialists use safe, painless, and cost-effective techniques to image the body and treat various diseases. It is a way to gather medical information that would otherwise be unavailable, require surgery, or necessitate more expensive diagnostic tests.

How do I prepare?

Wear comfortable clothing with no metal. Bring your physician's orders, insurance card and picture I.D. with you.  For your convenience, complimentary valet parking is available at the hospital's main entrance.  Family members are invited to stay in our waiting area for the duration of your procedure.
