Early Detection for Osteoporosis

dexa bone scan

About This Imaging Test

A DEXA (Dual Energy X-ray Absorptiometry) scan — also called DXA or a bone densitometry scan — uses X-ray imaging to measure bone density, also called bone mass. The test can identify osteoporosis, which is the gradual loss of calcium in the bones that increases the risk of fractures and breaks. By diagnosing osteoporosis at an early stage, your doctor may be able to help you slow progression of the disease, preventing further bone loss and bone fractures.

A DEXA bone density scan is not the same as a bone scan which is a nuclear medicine image used to detect arthritis, fractures, infections and tumors in the bones.

How the Test is Performed

Bone density testing can be done several ways.

The most common and accurate way uses a dual-energy x-ray absorptiometry (DEXA) scan. DEXA uses low-dose x-rays. (You receive more radiation with a chest x-ray.)

There are two types of DEXA scans:

  • Central DEXA. You lie on a soft table. The scanner passes over your lower spine and hip. In most cases, you do not need to undress. This scan is the best test to predict your risk of fractures.
  • Peripheral DEXA (p-DEXA). These smaller machines measure the bone density in your wrist, fingers, leg, or heel. These machines are in health care offices, pharmacies, shopping centers, and at health fairs.
