VQ Scan


Test date______________________ Test time______________________

This test will be performed in the Nuclear Medicine section of Radiology in the
UW Hospital. From the clinic entrance, go through lobby to 2nd floor atrium
elevators, then up to 3rd floor. Follow the signs to Radiology.

What is a V-Q scan?

The ventilation-perfusion scan is a test that studies both airflow and blood flow in
the lungs. V-Q refers to airflow and blood flow. The usual purpose of this test is
to look for signs of a blood clot in the lungs. This test will take about 1 hour to
complete.

You will be asked to breathe in a radioactive aerosol so we can image the airflow.
You will also have an IV placed in your arm. A radioactive substance will be put
in the IV that will reflect the blood flow to your lungs. Pictures will be taken of
your chest. This will help show areas of the lung that may have reduced blood
flow. Your doctor will share the test results with you.

How do I prepare for this test?

Please tell your doctor if you are pregnant. This test should only be performed
under special circumstances if you are pregnant. There is nothing else special you
need to do to prepare for this test.

How will I feel after the test?

The test is painless, except for the minor discomfort of having an IV placed.


What are the risks?

Many people worry when they hear that the tracers used in this test are slightly
radioactive. The amount of the tracers used is so small that there are no side
effects. Again, it should be noted that this test should only be performed under
special circumstances if you are pregnant.
