Dexa /BMD
What is a DEXA scan?
A DEXA scan, short for Dual-Energy X-ray Absorptiometry, is a non-invasive medical imaging technique used primarily to assess bone health and body composition. It is widely recognized as one of the most accurate methods for measuring bone mineral density (BMD) and is crucial in diagnosing and monitoring conditions such as osteoporosis and osteopenia.
How does the DEXA scan work?
The DEXA scan works by emitting two low-dose X-ray beams, each with different energy levels, which pass through the body. The amount of energy absorbed by the tissues and bones is measured, and this data is used to create detailed images of the bones. By analyzing these images, doctors can determine the density and quality of a patient's bones. A lower BMD indicates weaker and more brittle bones, which can be susceptible to fractures. DEXA scans are quick, and painless, and expose patients to minimal radiation, making them a safe and efficient diagnostic tool.
Who is subjected to a DEXA scan?
Many criteria are considered when determining who may benefit from a DEXA scan and how frequently it should be performed. According to research, women lose bone mass earlier and faster than men. As a result, it is frequently suggested that women receive a DEXA scan to check for osteoporosis at a younger age than men.
If you have one or more of the following risk factors for osteoporosis or fractures, you may be prescribed a DEXA scan:
- As people get older, they lose bone mass.
- If you have a family history of osteoporosis or have had more than one fracture, you may be at a higher risk of bone loss.
- If you have injuries from previous fractures like breaking a bone, especially beyond the age of 50, may indicate that you're more vulnerable.
- Porous (less dense) bones are more prone to breaking.
- Medications such as prednisone, cancer treatments, and pharmaceuticals used after an organ transplant can all damage your bones.
- Many chronic medical conditions might make your bones more prone to breaking. Rheumatoid arthritis, lupus, diabetes, liver disease, kidney disease, and other risky diseases.
