Bone Density Measurement (DXA Scan)

DXA (Dual energy X-ray Absorptiometry) Scan is used to measure Bone Density.  The test is done to look for Osteoporosis (where the bones are thin and weakened) and Osteopenia (where there is decreased bone mass) so that these conditions can be diagnosed and treated early to prevent bone fractures.

Who should have a DXA Scan

  • Post-menopausal women
  • Advancing age (woment over 65 years and men over 70 years)
  • Smokers
  • Low body mass index (BMI)
  • Small frame person
  • Family history of hip fractures
  • On long-term medication such as steroids
  • Excessive alcohol consumption

Your Bone Mineral Density (BMD) is compared to a reference range of healthy adults.  The difference between your BMD and the healthy adult score is known as the T-score.  Positive T-score suggest your bone is stronger than normal while a negative T-score suggest it may be weaker.

  • T-Score within 1.0 SD of reference range NORMAL
  • T-Score 1.0-2.5 SD below reference range LOW BONE MASS
  • T-Score 2.5 SD or more below reference range OSTEOPOROSIS

Discuss with your doctor about your results and any treatment required
