Bone Density Testing

What Is Bone Density Testing?

A bone density test measures the density of your bones to estimate their strength. Essentially, it's a measure of the health of your bones.

As you age, your bones naturally become less dense because existing bone is broken down faster than it's replaced. Minerals are constantly being added to and taken away from your bones. When minerals are lost faster than they are added, your bones become lighter, less dense, and more porous. This is called osteopenia, a natural process that begins in midlife. It makes your bones weaker and more likely to break. Bone density loss can begin earlier for some people, due to certain medical conditions or treatments, for example.

What Is Osteoporosis?

Osteopenia can develop into osteoporosis, a condition in which bones become thin and brittle. More than 25 million Americans suffer from osteoporosis, which can result in:

• Loss of height or a hump in your back
• Chronic pain
• Loss of movement due to bone fractures
• A higher risk of hip fractures

Why Is Bone Density Testing Necessary?

• To determine if you have or might develop osteoporosis
• To help your doctor recommend ways to prevent more bone loss and strengthen weak bones
• To determine if you are at risk for fractures, and help you take steps to minimize the risk
• To monitor your treatment and check your progress

Why Do I Need A Bone Density Test?

Your physician might order a bone density test if you have one or more of the following risk factors for osteoporosis:

• Women past menopause - When menopause occurs, the amount of estrogen (a hormone) in a woman's body decreases. Without estrogen, the body breaks down bone more quickly
• A condition (such as Cushing's syndrome or diabetes) that can weaken bones
• Taking medications (such as corticosteroids or thyroid medications) that can weaken bones
• Advanced age
• A family history of osteoporosis
• A diet low in calcium
• Smoking
• Excessive alcohol consumption
• Inactivity

What Can I Expect?

Because ordinary X-rays cannot detect mild bone loss, your bone density will be tested through the use of specially designed imaging equipment. The system uses small doses of radiation and provides information to a computer to determine the density of your bones. The testing technique is:

• Safe - There is very little risk involved
• Painless
• Simple - You will lie on a table or place your arm inside a machine
• Quick - Testing usually takes 5-20 minutes

What Do I Need To Tell My Doctor?

If you have questions about the specific technique that will be used to test your bone density, or if you have any other questions or concerns, ask your doctor. Issues you should discuss include:

• Pregnancy - A bone density test might not be safe if you are pregnant. If you are, or suspect that you are, tell your doctor immediately
• Medications - Make sure your doctor is aware of any medications you are taking

How Do I Prepare?

• Dress comfortably
• Avoid clothing with metal buttons, buckles or zippers
• Follow your healthcare provider's instructions about taking your medications before the test

How Do I Get The Results?

Your exam results will be sent to your physician, who will discuss them with you.

If you have any questions or comments about your procedure at any time, please talk to your physician or inform the staff. We want to make you as comfortable with the exam as possible.
