Usually, this scan is recommended post-menopause or after the age of 65 (when a woman’s risk of osteoporosis increases due to hormonal changes). It may also be recommended if you have a family history of osteoporosis.
At your DEXA scan appointment, you may be asked to change into a hospital gown. This prevents things like zippers, buttons, belts, and jewelry from interfering with the scan. Your doctor will then have you lie on the padded DEXA scan table, where a technician helps you get in a suitable position for the scan.
From there, the machine will typically pass over the top of your body, taking images and measurements of bones (to determine bone mineral density) and body composition (to determine the amount of fat and lean tissue in your body). This whole process is painless, non-invasive, and involves a low dose of radiation. From start to finish, it takes about 10-20 minutes, in which you’ll need to stay still the entire time.
