In brief: VQ scans
With a VQ scan, the v refers to "ventilation, and the q refers to blood flow.
The test is designed as a test for a blood clot in the lung. When this happens you have a blockage to blood flow (abnormal or reduced q) but normal air flow (ventilation). Other diseases in the lungs tend to reduce both v and q similarly.
