Nuclear Medicine Frequently Asked Questions
Q
Whats is a scan?
A
A small amount of radioactivity is used to obtain pictures that show how different organs of the body function. The pictures will help your doctor understand your illness.
Q
Is the scan safe?
A
Yes. We will ensure that the amount of radiation you receive is as little as possible. It is similar to an x-ray examination.
Q
Do i need to prepare for the scan?
A
For most scans you do not need to do anything special. You can eat and drink normally and keep taking your tablets. Your appointment letter will tell you if you have to do anything different from this. Please read it carefully.
Q
What is involved?
A
The radioactivity is usually injected into a vein in your arm. We take the pictures either immediately or at a later time as given on your appointment letter.
Q
How are the pictures taken?
A
The pictures are taken while you either lie on a bed or sit in a chair. A special camera is positioned close to part of the body being studied. The pictures take between 10 minutes and l hour to obtain. You will not normally need to remove any clothing and no discomfort is involved.
Q
Will it hurt?
A
No. You will only feel the slight "pinprick" of the injection. This is much the same as a blood test. We are well trained to give injections which usually do not hurt.
Q
Is there anything I should tell the staff before the scan?
A
If you are a woman, please tell us if you are pregnant or if you think you may be pregnant. Also, please inform us if you are breast feeding.
Q
Will there be any side effects?
A
No. The radioactivity is eliminated from the body very quickly. It will not make you feel sick or sleepy.
Q
What can I do after the scan?
A
You can go home or go to work but please avoid close contact with children or pregnant mothers for the rest of the day. You can drive a car, eat and drink normally and continue taking your tablets.
Q
What happens to the results of the scan?
A
We are unable to give you the results of the scan on the day you attend. We will send a report to the doctor who asked us to do the scan as soon as possible. The doctor will arrange a follow-up appointment.
