Vq Scan (Lung Ventilation and Perfusion)
WHAT YOU NEED TO KNOW:
A VQ scan is a test used to show the air flow and blood flow in your lungs. It is usually done if your healthcare provider thinks you have a pulmonary embolism (blood clot). A pulmonary embolism (PE) may be caused by a blood clot that travels from your leg to your lungs. A PE can become life-threatening. A VQ scan may show blood vessel blockages in your lungs. A VQ scan may be done before lung surgery to check how different parts of your lung are working.
Follow up with your healthcare provider as directed:
You may need other tests. Write down your questions so you remember to ask them during your visits.
Call 911 for any of the following:
- You feel lightheaded, short of breath, and have chest pain.
- You cough up blood.
- You suddenly have trouble breathing.
Contact your healthcare provider if:
You have questions or concerns about your condition or care.
Liquids help get radioactive substances out of your body. Ask your healthcare provider how much liquid to drink each day and which liquids are best.
