Bone densitometry, also known as Dual-Energy X-ray Absorptiometry (DEXA), is a non-invasive diagnostic procedure used to measure the bone mineral density (BMD). When this test is conducted on a single region of the body, it is often intended to identify bone-related health issues in that particular area. It is crucial in diagnosing conditions such as osteoporosis and assessing the risk of fractures.
Understanding your bone health is essential for maintaining overall health and wellness. Bones provide structure to our bodies, help with mobility, protect organs, and store calcium. A decrease in bone density can significantly impact quality of life, increasing the risk of fractures and causing debilitating pain. Therefore, understanding the current state of your bone density allows for prompt treatment and prevention of further bone loss.
Preparing for a bone densitometry scan is straightforward, with minimal specific requirements:
Note: Home Sample Collection is only for Pathology lab tests.
During the scan, you will lie on a padded table. A mechanical arm will move across the specific region being examined, emitting a small amount of X-rays .
The duration of the test is usually between 10 and 30 minutes, depending on the type of equipment used and the number of bones being examined.
No, the bone densitometry test is a non-invasive and painless procedure. You will, however, be required to remain still while the scan is in progress.
The frequency of bone densitometry tests depends on various factors such as your age, sex, health history, and current bone health status. Typically, post-menopausal women and men over 70 should have routine bone density screenings. Your doctor will recommend the appropriate frequency for you.
The results are reported as T-scores and Z-scores. The T-score compares your bone density to the optimal peak bone density of a healthy young adult of your same sex. The Z-score compares your results to people of your age, gender, and size.
If your test results indicate low bone density, it may be a sign of osteoporosis or another bone disease. Your doctor may recommend certain lifestyle changes or medications to improve your bone health.
Yes, bone density can be improved. Regular weight-bearing exercises, a balanced diet rich in calcium and vitamin D, and quitting smoking can all contribute to better bone health. Certain medications may also be prescribed by your doctor.
If your bone densitometry test results indicate any abnormalities, you should consult an orthopedic doctor or an endocrinologist. They can guide you in understanding the results and developing a personalized treatment plan.
Bone densitometry is a safe procedure, with a low level of radiation exposure. However, pregnant women are advised to avoid the test due to potential risks to the unborn child.
While it is safe for children, a bone densitometry scan is typically not performed on them unless it's necessary, as children's bones are still growing and changing.
Bone densitometry provides a window into your bone health, allowing you and your healthcare team to address any potential concerns promptly. It's an important tool in the prevention and management of osteoporosis and other bone diseases, helping to reduce the risk of fractures and maintain overall health and well-being. As with any medical procedure, ensure to discuss any questions or concerns with your doctor.
