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.
Lung VQ Scan. Also known as lung or pulmonary ventilation (V) and perfusion (Q) scans. A lung VQ scan is an imaging test that uses a ventilation (V) scan to measure air flow in your lungs and a perfusion (Q) scan to see where blood flows in your lungs. It uses special x ray scanners outside of your body to create pictures of air and blood flow patterns in your lungs.
