Nuclear Medicine Imaging

At Banner Health, we offer advanced nuclear medicine imaging to help detect and treat many health conditions. These imaging procedures use a small amount of radioactive tracers to create detailed pictures of how your organs and tissues are working. If your doctor has recommended a scan, we’re here to make sure you feel supported every step of the way.

What are nuclear medicine tests?

Nuclear medicine tests are safe, painless scans that help doctors see inside your body. Unlike regular CT scans, nuclear medicine provides dimensional images that show how your organs are working - not just how they look.

These tests use small amounts of radioactive material (called tracers), which may be injected, swallowed or inhaled. A special camera called a gamma camera detects the tracers to create the images.

These tests are helpful for diagnosis and treatment of conditions like heart disease, cancer and brain disorders.

Types of nuclear medicine procedures

The type of nuclear medicine scan you need will depend on the type of condition being evaluated. Common nuclear medicine procedures include:

  • PET scans (positron emission tomography): PET scans show cell activity, often used for cancer or brain imaging.
  • SPECT scans (single photon emission computed tomography): SPECT scans how blood flow and how organs work in 3D.
  • Renal scans: Help check kidney function.
  • Thyroid scans: Evaluate how your thyroid is working.
  • Bone scans: Detect bone injuries, cancer or infection.
  • Heart scans: Check blood flow to the heart and help diagnose heart disease.
  • Brain scans: Used to diagnose memory loss, seizures or stroke.

How to prepare for a nuclear medicine scan

Preparation instructions vary and may depend on the type of scan you’re getting. In general, you may be asked to:

  • Avoid caffeine for 24 hours
  • Not eat or drink for 6 hours before the scan
  • Pause certain medications

Your doctor will give you detailed instructions based on your specific test.

What happens during a nuclear medicine imaging test?

You will be given a small amount of a radioactive tracer, usually through an IV. After the tracer moves through your body:

  • A gamma camera will take images as the tracer collects in the area being studied
  • The scan may take 20 minutes to a few hours, depending on your test

These nuclear medicine scans give doctors a clearer picture of how your body is working. They can be an important step in getting the right diagnosis and treatment.

Is nuclear medicine safe?

Yes. Radiation exposure during nuclear medicine imaging is low. The small amounts of radioactive material used in the scan leave your body within a few days.

If you are pregnant or breastfeeding, talk to your doctor before your test. They can help you weigh the benefits and any possible risks.

Where can I get a nuclear medicine test?

You can get nuclear medicine scans at many Banner Health locations, including:

  • Hospitals
  • Clinics
  • Select Banner Imaging centers

Our care team is here to support you and answer any questions before, during and after your nuclear medicine procedures.

Frequently asked questions about nuclear medicine imaging

What does a nuclear medicine scan show?

These tests highlight how your organs and tissues are functioning. For example, they can show blood flow, metabolism or how well your heart or kidneys are working - rather than just structure.

How is nuclear medicine different from CT scans?

CT scans give detailed images of body structures. Nuclear medicine imaging shows how those structures are working, often by using radioactive tracers to create dimensional images.

Are nuclear medicine procedures safe?

Yes. These procedures use a small amount of radioactive material and involve low radiation exposure. The tracer typically leaves your body within a couple of days.

Will I need to prepare ahead of time?

Preparation depends on the type of nuclear medicine test. You may need to avoid food, drinks or certain medications. Your provider will give you clear instructions before your scan.

Where can I go for a nuclear medicine test?

Banner Health offers these tests at our hospitals, clinics and select Banner Imaging locations. Your doctor can help you schedule the right test for your needs.
