Bone densitometry, also known as DEXA or DXA, stands for Dual-Energy X-ray Absorptiometry. This imaging technique uses low-dose X-rays to measure bone mineral density (BMD). BMD refers to the amount of calcium and other minerals in your bones, which is essential for their strength and structure.

DEXA scans are the gold standard for diagnosing osteoporosis, a condition that causes bone loss and increases the risk of fractures. Early detection allows for timely treatment and prevention of fractures. DEXA scans can also be used to monitor the effectiveness of osteoporosis treatments and to assess your risk of developing fractures in the future.

No special preparation is required for a DEXA scan, and you can eat and drink normally beforehand. A DEXA scan typically takes about 10-15 minutes to complete.

What to Expect During a DEXA Scan:

1. You will be asked to lie on a padded table.

2. The DEXA scanner will move over your body, taking X-ray images of the bones in your spine, hips, or other areas.

3. You will need to lie still during the scan.

4. The scan is painless and typically takes about 10-15 minutes.

Overall, DEXA scans are a valuable tool for assessing bone health. If you are concerned about your risk of osteoporosis or have a condition that affects bone health, talk to your doctor about whether a DEXA scan is right for you.
