How long does a full body PET scan take?

The entire PET scan process takes about two hours. It can take up to 60 minutes for your body to absorb the injected radiotracer. During this time, you’ll need to sit quietly and limit your movements. The actual PET scan takes about 45 minutes.

What does a full body PET scan show?

It uses a radioactive tracer to pinpoint differences in tissues on the molecular level. 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.

What is the cost of a whole-body PET scan?

How much does a PET scan cost? PET scans nationally average around about $4,900 for the entire body, $6,700 for the brain and $6,800 for the heart.

Can a PET scan detect cancer anywhere in the body?

A variety of cancer cells become visible as bright spots in the images of PET scans. PET scans can help detect cancer and how far it has spread. PET scans can show solid tumors in the brain, prostate, thyroid, lungs, and cervix.

What cancers do not show up on a PET scan?

On the other hand, tumors with low glycolytic activity such as adenomas, bronchioloalveolar carcinomas, carcinoid tumors, low grade lymphomas and small sized tumors have revealed false negative findings on PET scan.

Is a PET scan worth it?

Not Only Worth the Cost, but Sometimes a Cost-Cutter! In some cases the added cost of PET imaging is offset by the savings achieved through the avoidance of unnecessary surgery. One of the common misperceptions about PET is that it is costly.

Why is my doctor recommending a PET scan?

A PET scan is an effective way to examine the chemical activity in parts of your body. It may help identify a variety of conditions, including many cancers, heart disease and brain disorders.

What is a whole body PET scan?

Positron emission tomography (PET) is a sophisticated medical imaging technique. It uses a radioactive tracer to pinpoint differences in tissues on the molecular level. A whole-body PET scan can detect differences in body functions, such as blood flow, use of oxygen, and uptake of sugar (glucose) molecules.

What to expect during a PET scan?

During the scan, the PET scanner will move around your body as you lie still. The scanner makes buzzing and clicking sounds, but the procedure is completely painless. The tracer used in the test contains small amounts of radiation.

What are the dangers of PET scan?

PET scans, CT scans, and PET-CT scans do have risks. One risk is radiation exposure. The radiation exposure from a PET-CT scan is similar to a total-body CT scan done with a contrast medium.
