Bone Densitometry

What is bone densitometry?

Bone densitometry is an X-ray like test that quickly and accurately measures the density of bone. It is used primarily to detect osteopenia or osteoporosis, diseases in which the bone's mineral and density are low and the risk of fractures is high.

Before your bone densitometry scan

If you think you may be pregnant, notify your physician. 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 medications that contain calcium, such as Tums, for 24 hours before your bone densitometry test.

On the day of your bone densitometry scan

Do not bring valuables such as jewelry or credit cards. You may be asked to wear a hospital gown for the test. After the test is performed, the results are reviewed by certified, specially trained technologists and board-certified radiologists.

During your bone densitometry scan

You will lie on your back, on a padded table, in a comfortable position. The lumbar spine (lower back) and the hip are the skeletal sites usually examined by bone densitometry.

After your bone densitometry scan

Generally, you can resume your usual activities immediately. The results of your bone densitometry test should be available to your physician within 24 hours after the test. Your physician will discuss the test results with you.
