Bone densitometry, also known as dual-energy X-ray absorptiometry (DEXA), is a medical diagnostic test that measures bone mineral density (BMD). The spine is a commonly scanned region because it is a load-bearing area of the body, and changes in its bone density could greatly affect an individual's mobility and overall health. It's often used to diagnose osteoporosis, a condition characterized by weak and brittle bones, and to monitor the effectiveness of osteoporosis treatments.
Understanding bone health is vital because bones serve many critical functions in the body. They provide structure, protect organs, anchor muscles, and store calcium. Diminished bone density can lead to health issues like fractures, which can significantly impact quality of life. A DEXA scan of the spine provides precise and important information about an individual's bone health.
When preparing for a bone densitometry spine scan, there are a few guidelines you may need to follow:
Note: Home Sample Collection is only for Pathology lab tests.
You'll be asked to lie on your back on a padded table while a mechanical arm moves over your spine, emitting a small dose of X-rays. The amount of radiation absorbed by the bones will then be measured.
A bone densitometry spine scan is relatively quick, usually taking between 10 to 30 minutes.
No, it's a non-invasive and painless procedure. You'll need to stay still during the scan to ensure accurate results.
The frequency of the test depends on various factors like age, sex, medical history, and current bone health status. It's often recommended that postmenopausal women and men over the age of 70 have routine bone density screenings.
The results are given as T-scores and Z-scores. T-score compares your bone density to the optimal peak bone density of a healthy young adult of the same sex. Z-score compares your results to average bone density of people of your age, gender, and size.
If your test results show low bone density, it could suggest osteoporosis or another bone disease. Your doctor will provide a suitable treatment plan that may involve lifestyle changes or medication.
Yes, bone density can be improved. Regular weight-bearing exercises, a diet rich in calcium and vitamin D, and quitting smoking are some ways to promote bone health. In some cases, your doctor may also prescribe certain medications.
If your test results are abnormal, you should consult an orthopedic doctor or an endocrinologist. They can help you understand the results and suggest suitable treatment options.
Bone densitometry is a safe and painless procedure with minimal radiation exposure. The benefits of diagnosing and treating osteoporosis or other bone diseases significantly outweigh the small potential risk from X-ray exposure.
Having strong and healthy bones is crucial to maintaining overall well-being. A bone densitometry spine scan is a vital tool in evaluating bone health, detecting bone loss early, and assessing the risk of fractures. It can guide your doctor in developing a personalized treatment plan, leading to better management of your bone health. Make sure to discuss any concerns or questions with your doctor to ensure the best care for your bones.
