A ventilation/perfusion lung scan, also called a V/Q lung scan, is a test to evaluate the circulation of air and blood within a patient's lungs. The ventilation part of the test looks at the ability of air to reach all parts of the lungs, while the perfusion part evaluates how well the blood circulates within the lungs. This test is most commonly done in order to check for the presence of a blood clot or abnormal blood flow inside the lungs (pulmonary embolism or PE). A V/Q lung scan may also be performed in the case of serious lung disorders such as COPD or pneumonia as well as a lung performance quantification tool pre and post lung lobectomy surgery.
This test takes ~ 45 minutes for both ventilation and perfusion imaging.
