DEXA Full Form
DEXA stands for Dual-Energy X-ray Absorptiometry.
Overview
- Purpose: DEXA is a medical imaging technique primarily used to measure bone density and assess the risk of osteoporosis and fractures.
- Technology: It utilizes two different X-ray beams to estimate bone density in various parts of the body, typically the hip and spine.
Key Features
- Non-invasive: The procedure is painless and does not require surgery.
- Low Radiation Exposure: DEXA scans expose patients to a minimal amount of radiation, much lower than a standard X-ray.
- Quick Procedure: The scan usually takes about 10-30 minutes to complete.
Applications
- Bone Health Assessment: Helps in diagnosing osteoporosis and other conditions affecting bone density.
- Monitoring Treatment: Can be used to track the effectiveness of medications or lifestyle changes aimed at improving bone health.
Who Should Get a DEXA Scan?
- Individuals over 65 years of age.
- Postmenopausal women, especially those with risk factors for osteoporosis.
- People with a family history of osteoporosis or fractures.
- Individuals with conditions or medications that affect bone health, such as rheumatoid arthritis or long-term corticosteroid use.
Conclusion
DEXA is a crucial tool in the early detection and management of bone health issues. If you think you might need a DEXA scan, consult your healthcare provider for personalized advice.
