A pulmonary infiltrate is a substance denser than air, such as pus, blood, or protein, which lingers within the parenchyma of the lungs. Pulmonary infiltrates are associated with pneumonia, tuberculosis, and nocardiosis. Pulmonary infiltrates can be observed on a chest radiograph.
A lung ventilation/perfusion scan, or VQ scan, is a test that measures air and blood flow in your lungs.A VQ scan most often is used to help diagnose or rule out a pulmonary embolism (PULL-mun-ary EM-bo-lizm), or PE. A PE is a sudden blockage in a lung artery.The blockage usually is caused by a blood clot that travels to the lung from a vein in the leg.verview. A VQ scan involves two types of scans: ventilation and perfusion. The ventilation scan shows where air flows in your lungs. The perfusion scan shows where blood flows in your lungs. Both scans use radioisotopes (a low-risk radioactive substance).
