PET CT Scanner & Patient










Your appointment letter gives the time and date of your appointment. If you cannot attend your appointment, please call the number on your letter and we will change it for you.

Please do let us know – otherwise a valuable appointment will be wasted.

Please contact us 48 hours before your scan if: 

  1. You are diabetic
  2. You are pregnant, breast-feeding or in contact with small children   
  3. You weigh over 100kg (16 stones)
  4. You suffer from any allergies or asthma  
  5. You are on thyroid medication   
  6. You are booked for any other appointments on the same day  

On the day

Please do not have anything to eat or drink for six hours before your appointment. This includes cough sweets and mints. You may sip water if you are thirsty.

Please take any medication you have been prescribed as normal, unless you are diabetic or on thyroid medication. If you are on this medication, please call the number on your letter for more details.

Avoid strenuous activity for 24 hours before your test.

When you arrive

When you arrive, we will ask you to fill in a patient questionnaire before taking you into the department.

We will ask you to remove any metal objects and may ask you to change into a patient gown. The procedure will be fully explained by one of our staff who will also take your brief clinical history.

Administration of the tracer

Once you are ready, we will give you an injection of radioactive material (the tracer) into a vein in your arm. The tracer helps us to get a better picture of the area we are scanning.

There are no side effects from the injection and it will not make you feel any different. We will ask you to remain lying down for an hour after your injection while it is absorbed into your body.


Once the tracer has been absorbed into your body, you are ready for your scan. In the scanning room you will be asked to lie down on your back on the scanning bed. The bed will move through the ring of the scanner and collect images for 30-60 minutes depending on the type of scan you need.

After this you are free to leave the department. We recommend that you avoid prolonged close contact with pregnant women or small children for at least eight hours after your scan.

We also encourage you to drink plenty of fluids for the rest of the day, as this will help to flush any unabsorbed tracer liquid out of your body.
