The Scoop on 'Full-Body Scans'

Q: What is a full-body scan?
Some medical imaging facilities are promoting the use of a new type of computed tomography (CT), also called computerized axial tomography (CAT), scanning. Known as whole-body CT scanning or whole-body CT screening (or "full-body scans" for short), it's marketed to healthy individuals who have no symptoms or suspicion of disease as a preventive health care measure. The cost of these scans ranges from $500 to $1,500. Unless required by a doctor, it's not likely to be covered by your health insurance.

Q: What does the U.S. Food & Drug Administration (FDA) say about full-body scans?
The FDA says it is unlikely that CT screening will benefit an individual lacking signs or symptoms of disease by detecting a serious disease early enough to treat it and alter the outcome significantly. The FDA does not endorse any such presumed benefit of whole-body CT screening.

Q: What are the outcomes of a full-body CT screening?
CT screening of a healthy person who has no symptoms of illness results in either normal findings or suspicious findings requiring follow-up tests. Normal findings carry the possibility of inaccuracy and false reassurance. For suspicious findings, follow-up may involve simple, non-invasive testing. It may also involve invasive procedures associated with surgical risks of anesthesia, bleeding, infection, and scarring, or it may entail radiological exams that could have associated radiation risks and potential risks of allergic reaction to injected contrast material.

Q: What should I do if I'm solicited for this procedure?
As with any type of medical procedure, you should first consult with your physician to discuss your options. With your doctor, you can deter-mine what kinds of tests may or may not be necessary to keep you healthy.

Statements by CT imaging facilities implying they have FDA "approval," "clearance," or "certification" of CT for screening procedures are misrepresent-ations. The FDA has never approved, cleared, or certified any CT system specifically for use in screening individuals without symptoms, because no manufacturer has ever demonstrated to the FDA that their CT scanner is effective for screening for any disease or condition.

There are no data demonstrating that whole-body CT screening of individuals without symptoms provides a greater probability of benefit than harm. Nor is there any study known to be under way to develop such data.

Quick Tips

Be Skeptical
If you are approached about having a full-body scan conducted, don't be swayed by arguments about their presumed benefits without first researching the facts.

Consult Your Doctor
Work with your physician to ensure you have regular checkups and screenings appropriate for your age and medical profile. These research-proven methods help doctors diagnose potential problems. And, if you are seriously considering having a full-body scan, by all means consult your doctor about the usefulness and medical necessity of the procedure.
