WebVentilation/perfusion scans, sometimes called a VQ (V=Ventilation, Q=perfusion) scan, is a way of identifying mismatched areas of blood and air supply to the lungs. It is primarily used to detect a pulmonary embolus . The perfusion part of the study uses a radioisotope tagged to the blood which shows where in the lungs the blood is perfusing.
