How it works
Nuclear Medicine imaging uses a small amount of a radioactive substance, called a radiotracer, which may be injected into a vein, swallowed or inhaled, depending on the type of scan. The Nuclear Medicine scanner detects the radiotracer and produces images that provide information about how different parts of the body are functioning.
Some Nuclear Medicine scans also include a low-dose CT scan, which provides additional information about the structure of the body.
At Lumus Imaging, Nuclear Medicine scans can be used to investigate many different parts of the body, including:
- Bones and joints
- Heart
- Lungs
- Gastrointestinal system
- Endocrine system
What to expect
The preparation and length of your appointment will depend on the type of Nuclear Medicine scan you are having. You will be provided with specific preparation instructions when your appointment is booked.
When you arrive, a Nuclear Medicine Technologist will talk with you about your medical history and explain the procedure. Depending on the type of scan, the radiotracer may be injected into a vein, swallowed or inhaled.
The timing of your images will also depend on the scan you are having. Images may be taken at the same time radiotracer is administered, shortly after, or you may need to wait or return later for imaging. Your Nuclear Medicine Technologist will explain the timing of your scan and let you know if you need to return to the imaging centre.
During imaging, you will usually be asked to lie on a scanner bed while the images are taken.

Frequently asked questions
Can I take my medication on the day of the test?
Most medications can be taken as usual, however, some Nuclear Medicine scans may require changes to when certain medications are taken. Please discuss your medications with our team when booking your appointment so specific instructions can be provided for your scan.
Please do not stop any medication unless you have been instructed to do so.
How is Nuclear Medicine different from X-rays and CT?
X-rays and CT provide structural information about an organ. Nuclear medicine is used to assess how the organ or bodily system is working. The imaging modalities are often complementary, each providing a piece of the puzzle to help diagnosis or assessment.
How will I feel after my scan?
Most people can continue with their usual activities after a Nuclear Medicine scan. Before you leave, your Nuclear Medicine Scientist will let you know if there are any specific instructions you need to follow.
You may be advised to limit close or prolonged contact with pregnant people and young children for a period after your scan.
Is the radiation harmful?
Nuclear Medicine scans use a small amount of radioactive material. The amount of radiation administered varies depending on the type of scan you are having and is carefully controlled to minimise your radiation exposure.
Depending on the radiotracer used, you may be given specific instructions to follow after your scan, including limiting close or prolonged contact with pregnant people or young children for a period of time.
Please let us know when booking your appointment if you are pregnant, think you may be pregnant, are breastfeeding, or are the primary carer for a young child, so that we can provide you with the appropriate advice for your scan.
What should I wear for my scan?
If possible, wear warm, comfortable metal free clothing. Do not worry if this isn’t possible, as you may be asked to change into a gown. Imaging departments can be cool, so warm clothing is recommended.
What special diet is required for my Nuclear Medicine scan?
For most nuclear medicine scans you can eat and drink normally before the procedure. If you need to fast, you’ll be told at the time of booking.
