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.24-Sept-2019
Why would a doctor recommend a PET scan?
A PET scan uses radioactive tracers to measure the chemical reactions in your body in order to diagnose diseases. A doctor will recommend a cardiac PET scan to check the blood flow to your heart muscles. The scan can indicate areas of decreased blood flow, which allows your doctor to accurately decide the next steps.
How is a lung PET scan performed?
How is a lung PET scan performed? For lung PET scan, you're injected intravenously with a small amount of glucose that contains a radioactive tracer substance about an hour before the scan. Most often, an isotope of the element fluorine is used. The needle may sting temporarily, but otherwise the procedure is painless.
Can a PET scan diagnose lung cancer?
Although lung tumors are often initially evaluated through a chest x-ray or CT scan, PET and PET-CT scans are highly accurate at determining whether a lung mass is cancerous and may even eliminate the need for surgical biopsy.
How accurate is a PET scan for lung cancer?
FDG-PET was reported to be 90% to 94% accurate in the characterization of malignant or benign lung nodules, with a sensitivity of 94% to 96% and specificity of 78% to 86%.
How long does it take to get the results of a PET scan?
When should I get my test results? A radiologist with specialized training in PET scans will review the images, write a report and send it to your healthcare provider. This process usually takes 24 hours.
How long does a PET scan of the lungs take?
The test takes about 90 minutes. PET scans are performed along with a CT scan. This is because the combined information from each scan provides a more complete understanding of the health problem. This combination scan is called a PET/CT.

Where does lung cancer usually start?
Lung cancers typically start in the cells lining the bronchi and parts of the lung such as the bronchioles or alveoli. A thin lining layer called the pleura surrounds the lungs. The pleura protects your lungs and helps them slide back and forth against the chest wall as they expand and contract during breathing.
Do you have to take your clothes off for a PET scan?
You will be asked to remove any clothing, jewelry, or other objects that may interfere with the scan. If you are asked to remove clothing, you will be given a gown to wear. You will be asked to empty your bladder prior to the start of the procedure.
