A lung positron emission tomography (PET) scan is an imaging test. It uses a radioactive substance (called a tracer) to look for disease in the lungs such as lung cancer.

Unlike magnetic resonance imaging (MRI) and computed tomography (CT) scans, which reveal the structure of the lungs, a PET scan shows how well the lungs and their tissues are working.
