Is a Bone Scan Necessary After an X-ray Has Been Taken?
26.03.2008 īņ M.VQUESTION: Is a bone scan necessary after an x-ray has been taken? I may have
to have this test and am wondering why, as well as what it will be like
Can
you describe it for me?
ANSWER: Bone scans are used to evaluate bones and to see into areas
containing abnormalities that have been caused by infections, fractures,
tumors, or other disorders
They are safe and sometimes provide more accurate
information than x-rays do.
If you must have a bone scan, a liquid containing a little radionuclide
(radioactive material) will be injected into a vein
In about two hours,
after your bones have absorbed that material, the scan begins
During it,
radionuclide emits signals that the scanner picks up and converts into images
of your bones
Signals from problem areas differ from normal ones, so that
they reveal areas where something may be wrong
Scans take about 45 minutes.
During the procedure, you lie still on a table as the scanner moves around
your body
Should the scanner be stationary, the table will be moved.
Immediately following the scan, you probably can return to work
Radionuclide
is excreted from your body within a day or two
The scan may clear up
questions that your x-ray was unable to answer, and assist your doctor in
making an accurate diagnosis.
The material contained here is “FOR INFORMATION ONLY” and should not replace
the counsel and advice of your personal physician
Promptly consulting your
doctor is the best path to a quick and successful resolution of any medical
problem.
