What Is A Pulmonary Perfusion Scan Used For
Radiological test: A ventilation-perfusion (v/q) scan is a specialized radiological lung test comparing mismatches between any part of your lung that still exchanges oxygen (affected in COPD e.g.) and any part that is not receiving blood flow. This is done through radio-tracers. A mismatch means there is a clot in that part of the lung hindering blood flow. Diseases & surgery of the lung complicate interpretation. ...Read moreSee 1 more doctor answer

Checks lung function: Pfts check numerous areas of lung capacity, flow rates, etc. And are useful in treating/diagnosing emphysema, copd, restrictive ariway diseases, asthma, and understanding lung capabilites prior to surgery. This would be common in smokers, elderly, or in patients with lung diseases like cystic fibrosis. Pfts are easy and done in a lab or pulmonary specialist's facility. ...Read more
