Bone Densitometry (DEXA) in Dallas, Texas
Dual-Energy X-ray Absorptiometry (DEXA) is a tool used for measuring bone density. DEXA calculates Bone Mineral Density (BMD), a measurement used to estimate bone strength and the likelihood of breakage and/or fracture.
What are some common uses of this exam?
- 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.

Who interprets the results and how do I get them?
The results of a DEXA 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 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 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.
What are the risk factors for osteoporosis?
While osteoporosis can affect anyone, it occurs most commonly in Caucasian and Asian females.
