What is a DEXA | Bone Densitometry?

DEXA is an imaging exam that measures bone density (strength). DEXA scan results can provide helpful details about your risk for osteoporosis (bone loss) and fractures (bone breaks). This exam can also measure your body composition, such as body fat and muscle mass.

Who is a Candidate For a DEXA Scan?

  • 65 years of age or older

  • Family history of osteoporosis

  • Low levels of testosterone

  • Previous bone fractures

  • Use of certain medications

  • Chronic diseases that affect the kidneys, lungs, stomach, and intestines

How to Prepare For a DEXA Scan?

Follow your physician's medication instructions and the imaging center's preparation guidance.

  • Do not take calcium supplements 24 hours prior to your scan.

  • If you have any other tests scheduled for the same day as your DEXA scan, then the exam must be performed first.

  • If you have any upcoming X-rays using contrast such as barium, IV contrast or any nuclear medicine studies, please have them completed at least one week prior to having a DEXA scan.

  • Vitamins and Fosamax are permitted.

How is a DEXA Scan Procedure Performed?

  • If you wear clothing without any snaps, buttons, or zippers, you will not have to change, but cotton gowns are available for use.

  • You will lie on a comfortable padded table while the arm of the instrument moves above you to scan your spine and hip. The instrument is open, and you will not be confined in any way. The technologist will position you by moving your arms above your head or by elevating your legs on a square cushion. You may notice some very minimal movement of the table when the images are being acquired.

  • A DEXA scan usually takes no more than 25 minutes.

What to Expect After a DEXA Scan?

  • You can leave immediately and resume normal activities.

  • Your exam will be read by a board-certified, sub-specialized radiologist.

  • Results will be sent to your ordering health care provider.
