Bone density scanning, also called dual-energy x-ray absorptiometry (DEXA) is an enhanced form of x-ray technology that is used to measure bone density. It is typically performed on the lower spine and hips.
It is used to diagnose osteoporosis and assess an individual's risk for developing fractures. It is quick, noninvasive and uses less than 1/10th the dose of a standard chest x-ray. Osteoporosis is a debilitating bone loss condition that affects one in three women after menopause. Although osteoporosis typically afflicts women, men can also develop bone loss. For women, a baseline scan is usually recommended at age 50 or post-menopausal. Subsequent scans are generally ordered every 2 years.
Do not take calcium supplements for at least 24 hours before the exam. Dress comfortably avoiding garments that have zippers, belts or buttons made of metal. You may be asked to wear a gown.
You will be asked to lie face-up on a padded table. An x-ray detector or arm is located above the table. To assess your spine, your legs are supported on a padded box to flatten the pelvis and lower spine. To assess your hip, your foot will be placed in a brace that rotates your hip inward. In both cases, the detector arm is slowly passed over the hip and spine generating images on a computer monitor. Just relax and remain still for a few seconds. It is a quick and painless procedure. There are no restrictions after the exam. You can expect a 30 minute appointment with a 10 minute scan time.
A radiologist will review the images and send a report to your referring physician within one business day. Your doctor will review the report and contact you with the results.
