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 CT scan of the lungs will also show signs of COPD, and can also be used to diagnose lung cancer. Blood tests. An arterial blood gas test measures how well the lungs are bringing oxygen to the blood and removing carbon dioxide. Test results show how severe your COPD is, and whether you may benefit from oxygen therapy.
