The DEXA machine uses low-dose x-rays to take pictures of your low back and both hips while you lie comfortably on your back. It looks at the soft tissue as well as the bone. The soft tissue amount can be subtracted from the total, and what remains is a patient's bone mineral density. If you have metal in your back or hips, your forearm may be scanned instead. this test takes approximately 20 - 25 minutes.
