There are several procedures which can be used to measure bone density, including: Dual energy x-ray absorptiometry (DEXA) – x-ray beams of differing energy are used to detect bone and soft tissue density separately. This technique can be used to measure bone density in the spine, hip, forearm and the total body.
The test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone. The bones that are most commonly tested are in the spine, hip and sometimes the forear
A bone density test is like an x-ray or scan of your body. The test doesn't hurt , and you don't need to do anything to prepare for it. It only takes about 15 minute
You should wear loose, comfortable clothing , avoiding garments that have zippers, belts or buttons made of metal. Objects such as keys or wallets that would be in the area being scanned should be removed. You may need to remove some clothing and/or change into a gown for the exam.
The exam is performed by a radiographer who specializes in X-ray . You will lie on your back on a padded table. You may be able to remain fully clothed or change into a patient gown. The machine will move slowly over the areas to be scanned.

In most cases, you do not need to undress . This scan is the best test to predict your risk for fractures, especially of the hip. Peripheral DEXA (p-DEXA) -- These smaller machines measure the bone density in your wrist, fingers, leg, or heel.
Bone density tests are easy, fast and painless. Virtually no preparation is needed . Be sure to tell your doctor beforehand if you've recently had a barium exam or had contrast material injected for a CT scan or nuclear medicine test. Contrast materials might interfere with your bone density test.
The only preparation needed is to delay taking your calcium supplement until after the test. Wear comfortable clothing preferably without metal (e.g. underwire bra, zipper, belt buckle) . Be sure to call the radiology facility the day before to review their instructions specific to your BMD.
You should wear comfortable clothes that have no metal zips or buttons. Or, we can provide you with a gown to change into. If you wear a bra we will ask you to take it off . We will take you into the scanning room and ask you to lie down on the scanner table (couch).
Before a Bone Densitometry Scan
You do not have to change your daily routine before this test. Eat, drink, and take any medications as you normally would. However, do not take calcium supplements or drugs that contain calcium, such as Tums, for 24 hours before your bone densitometry test.
