How To Prepare
Before the bone scan, tell your doctor if you:
- Are or might be pregnant.
- You are
breast-feeding. Use formula (discard your breast milk) for 1 to 2 days after
the scan until the radioactive tracer has been eliminated from your
body.
- Within the past 4 days, you have had an X-ray test using
barium contrast material (such as a
barium enema) or have taken a medication (such as
Pepto-Bismol) that contains bismuth. Barium and bismuth can interfere with test
results.
You may wish to limit your fluids for up to 4 hours before the test
because you will be asked to drink extra fluids after the radioactive tracer is
injected. You will empty your bladder right before the scan.
You usually have to wait 1 to 3 hours after the radioactive tracer
is injected before your bone scan is done. Therefore, you may want to bring
some reading materials or a project to pass the time during this waiting
period. For some types of bone scans, pictures are taken during the tracer
injection, immediately afterward, and then 3 to 5 hours after the injection.
You may be asked to sign a consent form before the test. Talk to
your doctor about any concerns you have regarding the need for the test, its
risks, how it will be done, or what the results will mean. To help you
