Is there any preparation for the scan?

One hour before the appointment time please go to Compton Ward. An anaesthetic cream will be applied to your child’s arm. This will numb the arm to stop the needle hurting and this takes between 30 and 60 minutes to take effect. A small needle will be put into a vein to enable us to carry out the injection. Afterwards, please come directly to the Nuclear Medicine Department, where an injection will be administered through the needle.

There are no other special preparations. Eat and drink as normal.

What happens when you arrive in Nuclear Medicine?

Once you arrive in Nuclear Medicine, your child will be asked to lie on the imaging couch. The injection will be given through the needle inserted in Compton ward.

How long between the injection and the scan?

The scan will be carried out immediately after the injection.

How are the images acquired?

The camera will be below the couch where your child will be lying. We will put velcro around your child to stop him/her from moving. This will not hurt your child but it is essential that your child does not move while each image is acquired. If your child has any favourite book, tapes, toys etc., please feel free to bring them with you to help keep him/her still. You can stay with your child thoughout the procedure. The scan will take about thirty minutes. When the scan has been completed, we will remove the needle.
