Frequently Asked Questions about Nuclear Medicine Scans

What is a Nuclear Medicine Scan?

A Nuclear Medicine scan is a specialized scan.

Does the scan involve an injection?

Yes. All patients getting Nuclear Medicine scans receive an injection. If you are an inpatient, most probably you will get your injection through your IV line. If you are an outpatient, you will receive your injection in your hand or arm.

What are you injecting into my body?

The injection is not a dye or contrast material. The injection is a low level, radioactive material. The injection will leave your body within a few hours. It is unlikely you will experience an adverse reaction.

Will the radioactive material harm me or anyone around me?


Will the test be painful?


How long will the test take?

The length of the test depends on what test you are receiving. The average time for most tests is one hour. Cardiac and Hepatobiliary scans may take longer.

Can I eat and take my medications?

It depends on what scan you are receiving. The doctor’s office, nursing personnel, and Medical Imaging has specific preparation sheets for your test.

Can I still receive the examination if I am breastfeeding or pregnant?

We must know if you are breastfeeding or pregnant. It’s possible your doctor and the Radiologist may choose a different examination for you.

Do I lay on the table?

For most examinations that we do, you lay flat on your back. We do use pillows and blankets to make you more comfortable.
