VQ Scan Test

What is a Ventilation Perfusion Scan?

A ventilation–perfusion (VQ) scan is a nuclear medicine scan that uses radioactive material (radiopharmaceutical) to examine airflow (ventilation) and blood flow (perfusion) in the lungs.

Who should get a VQ Scan?

Your doctor would refer you for this scan if the doctor suspects you might have a blood clot in your lung. A blood clot in the lung can sometimes be fatal, particularly if left untreated.

The most common early symptoms are shortness of breath and a sharp pain when you breathe in. Blood clots in the lungs often come from a clot in the leg called a deep vein thrombosis. A VQ scan will determine if a blood clot has travelled from your leg to your lung.

Is there radiation involved?

Yes. Nuclear Medicine is an imaging test which involves a small amount of radiation to show pictures of the organs, tissues, and bones of the body.

When will I receive my results?

Once completed, you will receive your results within 3-5 business days in your LabFinder portal.

How do I prepare? Do I need to fast?

Please refer to the simple preparation guidelines or consult with your doctor or radiology center where you are being treated. Do not forget to bring your LabFinder Order and Insurance Card to your appointment.
