DEXA (Dual Energy X-Ray Absorptiometry)

Dexa (Dual Energy X-ray Absorptiometry) is the most commonly used test for measuring bone mineral density. It is one of the most accurate ways to diagnosis Osteopenia or Osteoporosis. This quick and painless procedure should be done routinely for certain patients. UDI is the only radiologist-owned imaging facility in central Florida. Dr. George Stanley and his associates will interpret your scan promptly and share the findings with your physician.

About Osteoperosis

Osteoporosis is a common disease of the skeletal structure that causes a decrease in bone mass and density and can result in weakness and fracture in certain groups of individuals, especially postmenopausal women. In later stages, it is a painful, debilitating disease which causes bones to become brittle. Often we are not aware of this until we fall and break a bone or there are signs of curvature of the spine, back pain and loss of height. When this occurs it may be too late.

Early detection is key to prevention and treatment.

One in three post-menopausal women and one in eight men may be affected due to aging. Other contributing factors to bone loss are: reduced physical activity, consumption of alcohol, smoking, chronic renal failure and steroid therapy.

Additionally, a woman’s risk for hip fracture is equal to the combined risk of developing breast, uterine and ovarian cancer.

Who Should Be Tested?

The National Osteoporosis Foundation recommends that all women over 65 should be tested, as well as younger postmenopausal women who have any of the common risk factors for osteoporosis.

Why Do You Need a DEXA Scan?

With early detection, osteoporosis is a disease that can be prevented and treated. A DEXA Scan is quick, simple and non-invasive. It’s also the most accurate method for diagnosing osteoporosis at any stage.

How To Prepare For Your Imaging

DEXA Scans do not require any special preparation. Let your doctor and technologist know if there is a possibility you may be pregnant or if you have recently had a barium exam or received an injection of contrast material for a CT or radioisotope scan.

Wear loose clothing and leave jewelry at home. You may be asked to wear a gown. Please arrive 15 minutes prior to your exam. On the day of the exam, you may eat normally. You should not take calcium supplements for at least 24 hours before your exam.  There are no other preparations necessary.
