What is nuclear medicine and how does it work?

Nuclear medicine uses radioactive materials to help diagnose a variety of diseases and disorders. During the procedure, the patient is given a low-level radioactive compound that accumulates in a specific organ. The organ will then continuously emit radiation which is detected by a special camera and processed through a computer. The compound does not cause side effects or allergic reactions since most of the compounds used in nuclear medicine are naturally occurring substances found in the body. Nuclear medicine can be helpful in assessing how many different parts of your body are functioning, including the thyroid, heart, bones, brain, lung, liver and gallbladder.

What happens during your nuclear medicine test?

• Arrive early so you will have time to complete the registration process.
• A technologist will take you to the exam room, ask you some medical questions, explain what you can expect during your test, and answer any questions.
• You will be given a radioactive compound called an isotope which will be injected, inhaled, or swallowed, depending on what type of test you are having.
• If your test requires you to return at a later time after the isotope is administered, the technologist will tell you when to return.
• The length of your test will vary depending on what type of exam is being performed.

What happens when your test is complete?

• You can leave immediately after your test and resume your normal activities.
• The radiologist will review your scans and send the results to your physician. If urgent findings are uncovered, the results will be called into your physician immediately.
