DEXA Bone Densitometry Screening measures the density of your bones and can be used to follow changes in bone density over time. A DEXA screening is easy, painless, and the radiation used is only a fraction of that received from a standard chest x-ray. Bone Densitometry is a safe and painless test that uses advanced technology called DEXA (Dual-Energy X-ray Absorptiometry) to measure symptoms of osteoporosis—such as low density and mineral content of bone, that may have developed unnoticed over many years. Because osteoporosis can result in bone fractures that can cause chronic pain and disability, it is important to begin treating osteoporosis at an early stage. Bone densitometry can detect the early signs of osteoporosis so that patients can begin treating it before a debilitating fracture occurs.
What to Expect
During a comprehensive DEXA bone evaluation, a patient lies comfortably on a padded table while the DEXA unit scans one or more areas of his/her body, usually the spine or hip because they are particularly prone to fracturing. Bone densitometry produces little radiation. It is noninvasive, involves no injections and, depending upon the number of areas to be scanned, can take just minutes to complete. After the exam, you may return to work or home and resume normal activities. The radiologists will promptly review and interpret your images and deliver a report to your physician.
Preparations and Precautions
Do not take any calcium supplements or antacids for 24 hours before your appointment. Please be sure to bring your referral from your doctor with you when you come for your appointment. If you do not have it with you, we may not be able to perform your test. Also, arrive at least 10 minutes early to register.
