Bone Densitometry

---

AllianceHealth Durant offers bone densitometry, also known as a bone density test, DXA or DEXA (dual energy X-ray absorptiometry). Bone densitometry measures the strength of your bones to determine whether you are at risk for developing osteoporosis or osteopenia (decreased bone mass or a lower bone mineral density). Osteopenia often develops into osteoporosis. Doctors use the test to develop an appropriate treatment plan to slow the progression of disease and prevent fractures and bone loss. Early detection through bone density testing can allow doctors to begin therapy when it can be most beneficial.

Osteoporosis is caused by more bone cells being resorbed than being deposited. This imbalance results in a progressive loss of bone density and a thinning of bone tissue. Osteoporotic bones are more porous and therefore more vulnerable to fracture.

What is a DXA Bone Density Test?

DXA (or DEXA) is the most widely used test to measure bone mineral density. A DXA bone density test is more accurate than a regular X-ray or CAT scan and requires less radiation exposure. A DEXA scan is now the best method of diagnosis and monitoring osteopenia and osteoporosis.

Using bone density testing (or bone densitometry), physicians can measure patient bone density and follow it over time. If the patient's bone density is low, or decreases at an abnormally fast rate, the patient may be at risk for osteoporosis. Through changes in diet, exercise habits and/or medication, risk factors can be lessened and further bone loss or weakness can be prevented.
