Frequently asked questions about Nuclear Medicine

Frequently asked questions (FAQs) about Nuclear Medicine.

Normal Heart Scan

Will the scan hurt?
No the scan is completely painless. The injection is no more painful than having a blood test.

Where is the injection site?
Usually into a vein in the arm. Just like a blood test.

Is Nuclear Medicine safe? I've heard that radioactive things are harmful.
Yes. Nuclear Medicine is safe. The amount of radiation you get having one of our scans is similar to having x-rays or a CT scan.

Is it safe to go near people once I have had my injection?
Yes.

Will I glow in the dark?
No

Can I eat and drink before the scan?
Many of our scans require no preparation. You may eat and drink as usual. There are some scans that require you to fast beforehand or to abstain from drinks containing caffeine. You will be provided with detailed instructions with your appointment.

Is it safe to drive afterwards?
Yes.

Are there any adverse reactions to the injection?
No. The tracers we use have not been known to have any adverse reactions.

Do I have to change into a gown for the scan?
For many of our scans you can remain in the clothes you are wearing. All that is required is you remove jewelry and empty your pockets. For some scans, such as those looking at your heart, we will need you to change into a hospital gown.

When will I get the results?
We aim to have the scan read by our consultant and dispatched to your doctor or specialist within 24 hours.
