Bone Densitometry & Dxa Scans in Dallas
What is a Bone Density Scan
Dual-Energy X-ray Absorptiometry (Dxa) is a tool used for measuring bone density. Dxa calculates Bone Mineral Density (BMD), a measurement used to estimate bone strength and the likelihood of breakage and/or fracture.
Common Uses of Dxa Scans
- Aiding physicians in the diagnosis and treatment of osteoporosis.
- Assessing an individual’s risk for developing fractures. Emphasis is placed on the spine and hips, which are weight-bearing areas that are more susceptible to fractures.
What to Expect
- You will not have to change into a gown for this exam if you wear loose, comfortable clothing without zippers or metal buttons.
- You will be asked to lie on a padded table and hold very still for approximately five minutes.
SWDIC technologists are experienced in high quality patient care. Communication with your technologist is vital in ensuring your comfort, as well as the attainment of quality diagnostic images
Who interprets the results and how do I get them?
The results of a Dxa bone density exam are interpreted by a radiologist and forwarded to your doctor. Your test results will be in the form of two scores:
- T score – This number shows the amount of bone density you have, compared to a young adult of the same gender with peak bone mass. A score above -1 is considered normal. A score between -1 and -2.5 is classified as osteopenia, the first stage of bone loss. A score below -2.5 is defined as osteoporosis. It is used to estimate your risk of developing a fracture.
- Z score – This number reflects the amount of bone density you have, compared to other people in your age group and of the same size and gender. If it is unusually high or low, it may indicate a need for further medical tests.
Risk Factors for Osteoporosis
- Low body weight
- Estrogen deficiency
- Early menopause
- Surgical removal of both ovaries
- Prolonged menopause
- Absence of a period for more than one year
- Low calcium intake

While osteoporosis can affect anyone, it occurs most commonly in Caucasian and Asian females.
