Bone densitometry measures your bone mineral density, which is a sign of bone strength. Density measurements are taken at specific areas of your body. Those measurements are compared to a database of normal individuals of your same age, sex, and race. The results show whether you have lost bone density. The measurements also help determine the presence of osteoporosis and can be used to estimate your risk of bone fracture.

A radiographer explains the procedure and asks you several questions about your medical history. The technologist positions you on a padded table and asks you to remain as still as possible during the test. The DXA exam is completely pain free. The exam takes about 15 to 20 minutes.

Your physician provides you with detailed instructions describing how to prepare for your procedure. Wear loose, comfortable clothing, avoiding garments that have zippers, belts or buttons made of metal. Note: Women should always inform their physician or x-ray technologist if there is a possibility they are pregnant.

A radiologist, a physician specially trained to diagnose conditions and diseases, interprets the results of a DXA bone density exam. The radiologist sends an interpretation of your results to your primary care physician. Your doctor discusses these results with you and explains what they mean in relation to your health.
