When can PET scan be repeated?

Conclusions: The optimal time to perform a repeat FDG-PET/CT scan after the completion of neoadjuvant chemotherapy and high-dose radiotherapy to maximize its accuracy for restaging patients with NSCLC is about 1 month after the last dose of radiation.

How and when should PET Scans be used? What do they show?

What should I avoid after a PET scan?

How long is a PET scan valid?

A PET scan is considered to be a safe procedure. It exposes you to around the same amount of radiation that you would receive from the general environment over about three years. The injected radioactive chemicals have a very short lifespan and are removed from the body fairly quickly.

Is a PET scan more expensive than a CT scan?

PET scans take between 2-4 hours to complete, and are significantly more expensive than CT scans. The radiation exposure of a PET scan is about the same as an x-ray.

Does inflammation show up on PET scan?

A PET (positron emission tomography) scan is an imaging test. A PET scan can see how tissues and organs in your body are working and find disease or inflammation.

Does a PET scan cover the whole body?

A whole-body PET scan can detect differences in body functions, such as blood flow, use of oxygen, and uptake of sugar (glucose) molecules. This allows your doctor to see how certain organs are functioning.
