A DXA (Dual Energy X-Ray Absorption) scan is a simple, painless, non-invasive bone density testing procedure. The test measures your Bone Mineral Density (BMD) or bone mass and compares that number with a reference population whose age, sex and racial background are similar to yours. This information will help your physician determine if you need to take any specific steps to protect your bone health.
While some bone loss occurs universally with aging, in an advanced state, bone loss can lead to Osteoporosis. Osteoporosis reduces the strength of your bones and they become brittle and prone to fractures, robbing many of their mobility and independence. DXA is key in the early detection of Osteoporosis.
Key Facts on Osteoporosis:
- Women are 8 times more at risk to develop osteoporosis than men.
- Approximately 50% of women over the age of 50 have osteoporosis and are at risk of an osteoporosis-related fracture.
- A woman’s risk of hip fracture alone is equal to the risk of developing breast, uterine and ovarian cancer combined.
Preparation and what to expect during the procedure:
- The procedure requires you to lie still on an exam table for ten minutes while your vertebrae in the lower spine and hips are adjusted.
- A DXA bone density scan does not require any special preparatory drinks, medications or injections.
