Tekrotyd Scan

What is a Tekrotyd Scan?

A Tekrotide scan helps identify and localize certain abnormal tissues associated with neuro-endocrine diseases


There is no special preparation for the examination, and you may eat and drink normally before your appointment.

Please contact us if you are having somatostatin analogue therapy as this will interfere with the exam and your appointment may need to be rescheduled.


If you are pregnant or breastfeeding it is essential that you let us know before your appointment date. If you are a female of child bearing age (12-55 years old), you will be asked about your pregnancy and breastfeeding status. If you are unable to confirm you are not pregnant a pregnancy test may be performed.


All patients are entitled to have a chaperone present for any consultation, examination or procedure where they feel one is required.

The examination

Upon your arrival a radiographer will explain the procedure to you and will ask you a few questions about your health records. You will then have a small amount of radioactive tracer injected into a vein in your arm. The injected tracer is carried through the bloodstream to your body tissues. It emits gamma rays which can be detected by a piece of equipment called a gamma camera.

You will be sent away and asked to return 4 and 24 hours after injection for the scan. This time gap is to allow the tracer to be fully absorbed into your body tissues for us to see it. Between the injection and the images acquisition you may eat as normal but you should drink more than usual and empty your bladder regularly. This will help to produce better quality pictures.

When you return for imaging we will ask you to empty your bladder and then we will ask you to lie on your back on the scan table. The camera will be placed above and below your body and the machine will move slowly from your head to your toes acquiring images of your body. The machine is very quiet and you do not go through a tube or tunnel.

Who will be present?

Your scan will be performed by a Nuclear Medicine trained member of staff which stays with you in the room while scanning.
