Bone Scan
What is a Bone Scan?
This
is a test in which a small amount of radioactivity is used to obtain pictures
of your bones with a gamma camera. These pictures will help your doctor
make a diagnosis.
What is involved?
A small amount of radioactive tracer is injected into a vein, usually in your arm. The injection is no more painful than a blood test.
You
may then have pictures taken immediately and after a delay of about two
to three hours, depending on the type of scan you are having. For the scan
you will be asked to lie on a bed whilst the gamma camera obtains the images.
You
do not normally have to undress but we will ask you to remove any metal
objects such as jewellery.
Is the radiation dangerous?
The amount of radiation you receive is small; it is comparable to that of an X-ray examination. The substances we inject are non-toxic and will not make you feel sick or drowsy. However, for radiation safety reasons pregnant women and children should not be brought to the Nuclear Medicine Department.
What about pregnancy?
Please tell us as soon as possible before the injection if you are pregnant or think that you may be pregnant. All female patients between the ages of 10 - 55 years will be asked to complete a form on arrival.
What about breastfeeding?
Radioactive substances can come out in breast milk. Please phone the Nuclear Medicine Department before your test if you are breastfeeding, so that we can advise you if you need to stop feeding for a length of time.
How long will it take?
The waiting time between having your injection and going in for the scan is about two to three hours. Your appointment letter will show two separate times, one for the injection and one for the scan. The scan itself will take about 30 minutes.
Can I bring a friend or relative with me?
A friend or relative can attend with you but they will not be able to accompany you for the injection or scan.
Do I need to do anything after the scan?
You can eat as normal, but you should drink more than usual for the rest of the day to help wash the tracer out of your body.
Can I still look after children and pets?
Please try to avoid prolonged close contact with small children and babies for the rest of the day; this is to avoid exposing children to unnecessary radiation. The radioactive material you will be given will not affect any pets you may have.
Can I return to work after my scan?
There is usually no problem, but if your work involves radiation or close contact with children or pregnant women please ask Nuclear Medicine staff for advice.
What about my result?
We are unable to tell you the result of the test. The scan is reported by a Radiologist and the result is sent to the doctor who requested the test. However, the staff performing the test are fully qualified and will be happy to answer any other questions you may have.
