Lung Scan
Nuclear Scan, Lung, Ventilation and Perfusion Scan
Why It Is Done
A lung scan is done to:
- Find a blood clot that is preventing normal blood flow (perfusion) to part of a lung (pulmonary embolism).
- Evaluate the flow of blood (perfusion) or air (ventilation) through the lungs.
- See which parts of the lungs are working and which are damaged. This is often done before lung surgery to remove parts of the lung.
