Osteoporosis and Bone Densitometry (DEXA) Scans
Osteoporosis is the most common type of bone disease where a person’s bones become weak and are likely to break. It occurs when the body fails to form new bone, or when too much bone is reabsorbed by the body. This disease can be prevented and treated and, like many others, is treated the most effectively when caught early.
Risk factors for Osteoporosis include:
- small and thin body types
- age (65+)
- eating disorders
- family history
- gender (women)
- postmenopausal
- smokers
- alcohol abusers
- lack of Vitamin D
- lack of Calcium in a diet
Bone density tests, also known as DEXA scans (duel energy x-ray absorptiometry) are useful in diagnosing osteoporosis by using a low-dose x-ray that checks for signs of mineral loss and bone thinning. By scanning the hip, hand, spine, or foot, DEXA scans also alert technologists and physicians about other potential medical conditions that the patient may have that is causing bone loss, also known as osteopenia.
What should I expect during the exam?
During your DEXA scan, you will lie on a padded table while a mechanical arm-like device passes over your body. The device will not touch you, but does emit a small amount of radiation. The study takes only about 15 minutes. You will need to lie perfectly still during your exam for the most accurate results. You should not wear jewelry or metal to your exam, because it may interfere with your results. The DEXA study is an excellent tool for determining your bone density but does not determine the cause of your score.
The following target groups are specifically at risk and should have regular DEXA scans:
- Women ages 65 and older
- Men and women ages 60 and older who are at increased risk of having osteoporosis.
Other individuals may be at high risk and could be recommended for DEXA scans by their physician. Talk with your primary care physician about your risk factors. You will need a physician’s order to schedule a DEXA scan.
When will I be informed of my results?
After your DEXA scan, the radiologist will mail or fax the results to your physician. The average turn-around time for Radiology reports at J.C. Blair is about 8 hours unless the radiologist needs to research more information about your medical history or previous studies for comparison. Your physician will schedule an appointment with you where he or she will discuss the study results.
Treatment and Prevention of Osteoporosis
In addition to taking medications, you can help prevent bone loss by making a few small lifestyle changes.
- Include plenty of calcium, Vitamin D, and protein in your diet.
- Limit alcohol or caffeine intake.
- Quit smoking.
- Exercise regularly.
- Prevent falls.
