Bone Density Study
An Imaging Exam for Detecting Bone Loss
Could Your Bones be at Risk of Osteoporosis?
After menopause, most women experience bone loss, which can eventually lead to osteoporosis, a disease that causes bones to become fragile and increase the chance that ones will break.
It is estimated that there are over 20 million women in America with osteoporosis, yet relatively few have been diagnosed or treated.
It is recommended that a baseline DEXA scan be performed prior to menopause or at age 40 to 45.
What is a Bone Density Study?
A bone density study measure the calcium content (density) of your bones. The medical name for this test is a Dual Energy X-ray Absorptiometry Scan (DEXA). This is a scanner that uses tiny amounts of radiation. Scans of your lower back and hip are most often taken. This painless exam takes about 20 minutes to perform.

Normal bone structure is dense, with fewer porous regions. |
In osteoporosis, there are more porous regions. The structure of the bones becomes fragile. |

Tell the Technologist
Instruct the technologist if you:
- Are pregnant or think you may be pregnant
- Have metal in the part of your body being imaged, such as spinal fusion rods or hip replacements;
- Have had a recent nuclear medicine scan or a barium enema; or
- Have a severely curved spine, have had spinal surgery, or cannot lie on your back.
Your Exam
The exam will consist of you lying on a table. For part of the test, your lower legs may be raised on a platform. A scanner will move back and forth over your body. You will be asked to stay still.
After Your Exam
When your exam is over, you can return to your normal routine. Your physician will inform you of the results of the scan.
Risk Factors
The following are risk factors that could increase your chances of developing osteoporosis:
- Being female
- A small, thin frame
- Advanced age
- Family history of osteoporosis
- Early menopause
- A diet low in calcium
- Use of certain medications
- Cigarette smoking
- Excessive alcohol intake
Osteoporosis Can Be Treated
- Getting enough calcium and Vitamin D
- Doing weight-bearing exercises
- Using appropriate prescription medications as directed by your health care provider to slow or reverse bone loss
Exam Tips
- Follow any instructions you are given about taking medications or food supplements.
- Be ready to discuss your overall health.
- Bring a list of medications you take.
- Wear clothing with no metal closures.
