Nuclear Medicine: Lung Scans

The lungs are a pair of organs in the chest that are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and our blood. There are many conditions that can impact the health of your lungs: Asthma, COPD, Tuberculosis, Bronchitis, Pleurisy, Pneumonia, Emphysema, Pulmonary Embolism (blood clots), etc. 

Lung imaging involves two phases: assessing ventilation (air flow in and out of the lungs) and assessing perfusion (blood flow to the lungs).
