Bone density scanning is an advanced form of x-ray technology that is used to measure bone loss. DXA is today’s established standard for measuring bone mineral density (BMD).
The bone density scan is used to assess the strength of the bones and their ability to bear weight, and is most often used to diagnose osteoporosis, a condition marked by gradual structural changes and loss of calcium causing the bones to become thinner and more fragile.
The scan can help to predict fracture risk based on T SCOREs (standardised measurements by the World Health Organisation). Measurements are graded into normal [T SCORE > -1], low bone mass [osteopenia and T SCORE -1 to -2.5], osteoporosis [T SCORE > -2.5].
Who should have a Bone Density Scan?
- Post-menopausal females
- Anyone who has been on steroid treatments for longer than 3 months
- Anyone with a thyroid disease
- Anyone with a history of bone fractures an adult
- People with thin body stature, low calcium intake or decreased physical activity
- Anyone who uses caffeine excessively
