How it works
PET/CT imaging uses a small amount of a radioactive substance, called a radiotracer, which is injected into a vein. The scanner detects the radiotracer and produces detailed images showing its distribution and activity within the body.
The PET/CT scanner looks similar to a CT scanner and provides information about both the structure and function of the body.
At Lumus Imaging, PET/CT scans can be used to investigate:
- Cancer
- Neurological conditions, such as Alzheimer’s and Parkinson’s disease
- Infection
- Inflammation
What to expect
The preparation and length of your appointment will depend on the type of PET/CT 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.
A cannula will be inserted into a vein, usually in your arm, and the radiotracer will be given through the cannula. Depending on your scan, you may be asked to rest in a quiet room or be given a time to return to the department for your imaging.
When it is time for your scan, you will be asked to lie on the PET/CT scanner bed. The scanner looks similar to a CT scanner, and the time required to take the images will vary depending on your examination.
After your scan, the Nuclear Medicine Technologist will check the images to make sure they are clear. Occasionally, additional images may be needed. You will then be able to leave the imaging centre.

Frequently asked questions
Can I take my medication on the day of the test?
Most medications can be taken as usual; however, some PET/CT scans require changes to when certain medications are taken. This is particularly important if you have diabetes or take medication for diabetes. Please discuss your medications with our team when booking and follow the specific instructions provided for your scan.
Please do not stop any medication unless you have been instructed to do so.
How will I feel after my scan?
Most people can continue with their usual activities after a PET/CT scan. Before you leave, your Nuclear Medicine Scientist will let you know if there are any specific instructions you need to follow after your scan.
You may be advised to limit close or prolonged contact with pregnant people and young children for a period of time after your scan.
Is the radiation harmful?
PET/CT 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 if I am claustrophobic?
Most people with claustrophobia can complete a PET/CT scan. Please let us know when booking if you have any concerns about claustrophobia so we can discuss these with you before your appointment. You may also wish to bring an eye mask to wear during the scan.
What preparation is required for my PET/CT scan?
The preparation for your scan will depend on the type of PET/CT scan you are having. You will be provided with specific preparation instructions when your appointment is booked.
It is important to follow these instructions carefully, as not following the required preparation may affect your scan and could mean that your appointment needs to be rescheduled.
What should I wear for my scan?
If possible, wear warm, comfortable metal-free clothing. Don't 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.
