Bone Densitometry

Learn your bone strength to help you live at your best.

A bone density scan, also known as a dual-energy X-ray absorption (DEXA) or bone densitometry test, is a type of specialty nuclear medicine that measures the strength of your bones. A bone density scan is more precise than traditional diagnostic imaging, like X-rays.

What a Bone Density Scan Is Used to Diagnose

A bone density test (DEXA scan) can help you and your care team discover if you have bone loss early, before it becomes severe.

Your DEXA scan measures the density of the bone in various parts of your body. Your bone density results will then be compared with the peak bone mass of a healthy adult of your same sex to determine how strong your bones are.

Who Should Get a DEXA Scan?

Your provider may recommend a bone density test if you have high osteoporosis risk factors like:

  • Close relative (like father or grandmother) with osteoporosis or bone fractures
  • Low body weight, slight build, or light complexion
  • Caucasian or Asian heritage
  • Early menopause (before the age of 45), naturally or surgically
  • Use of medication (over a long period of time) that accelerates bone loss, such as corticosteroids or some anti-seizure medications
  • Previous bone breaks that may be the result of thinning bones
  • History of cigarette smoking or heavy drinking

A DEXA scan typically takes 15 to 20 minutes.

The machine's detector will slowly pass over the area scanned. You will lie still:

  • Spine: flat on your back with your legs elevated.
  • Hips: on your back with your legs outstretched. Both hips will be scanned, unless you have had a hip replacement; then the hip without replacement will be scanned.

If both your hips have been replaced, only your spine will be scanned.
