Pulmonary ventilation (eg, aerosol or gas) and perfusion imaging

AI EXPLANATION: A ventilation-perfusion (V/Q) lung scan is a specialized nuclear medicine imaging test that examines airflow and blood circulation within the lungs. During the procedure, an individual breathes in a safe aerosol or gas to show how well air moves through the airways, and a small amount of an imaging tracer is delivered through a vein to show blood flow. A specialized camera captures detailed images of the lungs, allowing doctors to detect blood clots, evaluate lung function, and identify areas with restricted air or blood supply.
