Lung PET Scan. Definition. A lung positron emission tomography (PET) scan is an imaging test that uses a radioactive substance (called a tracer) to look for disease in the lungs, especially lung cancer.
A lung scan is a type of nuclear scanning test. It is most often used to find a pulmonary embolism. This is a blood clot that prevents normal blood flow in the lung. Two types of lung scans are usually done together: Ventilation scan. During this scan, you inhale a radioactive tracer gas or mist. Pictures from this scan can show areas of the lungs that aren't getting enough air or that hold too much air.
