Lung V/Q Scan
What to Expect During the Procedure
This procedure is a two part test. The first part evaluates the ventilation function of
the lungs. You will be seated in a chair and fitted with a breathing tube similar to a snorkeling apparatus and will be instructed
to breathe through the tubing for approximately 5 minutes. The air breathed in is mixed with a radioactive tracer to visualize the air
distribution within the lungs. When breathing is complete you will lie on the table on your back.
Images are acquired in various positions for approximately 20 minutes. The second part of the study evaluates blood circulation in
the lungs. You will receive an intravenous injection of a radioactive material in your hand or arm. Images are
acquired in the same positions as the ventilation scan for approximately 20 minutes. If a chest x-ray has not been done in the past
24 hours or is not available for review, a routine chest x-ray will be done before you leave the facility. There are no
common side effects.
