What is a Lung Scan?


------------------------------------------------------------------------------

QUESTION:  I need a bit more information to add to the explanation my
physician gave me about a test for my lungs.  Its called a "scan" and I want
to know more about it.  Is there any danger, I am more than just a bit anxious
about this whole thing.  Can you please help?

------------------------------------------------------------------------------

ANSWER:  A lung scan is a test that shows how well your lungs are functioning
and can detect many types of abnormalities in the lungs.  There are two types
of lung scans and they are usually performed together.  A perfusion lung scan
shows the blood circulation in the lungs.  An inhalation scan shows how well
air moves in the lungs.
     Both tests together take about a half hour and are similar.  A small
amount of a mildly radioactive compound is administered and travels to the
lungs, emitting signals that are detected by a scanning machine, which
converts the signals into images.  For the perfusion test, you'll receive an
injection of the radioactive substance.  For the inhalation test, you'll
inhale an odorless gas through a mouthpiece.  You may be placed in several
positions during the scan and it is very important that you lie still, and
follow all instructions fully.  This will help get the best results possible
and make interpreting the results a bit easier.  The danger from the
radioactive compound is minimal.  You can go home directly after the test and
side effects are rare, so you ought to do quite well.  I hope you are less
anxious now.
