DEXA Scan: Full Form and Overview
DEXA stands for Dual-Energy X-ray Absorptiometry. It is a medical imaging technique primarily used to measure bone density and assess bone health.
Key Features of DEXA Scans:
- Dual Energy: Utilizes two different X-ray energies to differentiate between bone and soft tissue.
- Bone Density Measurement: Helps in diagnosing conditions such as osteoporosis.
- Quick and Non-Invasive: The procedure is typically fast, taking only about 10-30 minutes, and is painless.
- Low Radiation Exposure: The amount of radiation exposure during a DEXA scan is very low, making it safe for patients.
Common Uses of DEXA Scans:
- Bone Health Assessment: Identifying risk for fractures and monitoring bone health.
- Body Composition Analysis: Measuring fat and lean mass distribution in the body.
- Monitoring Treatment: Evaluating the effectiveness of osteoporosis treatments over time.
Conclusion
In summary, DEXA (Dual-Energy X-ray Absorptiometry) is a vital tool in medical diagnostics, particularly for assessing bone density and overall skeletal health. Its quick, non-invasive nature and low radiation exposure make it a preferred choice for both patients and healthcare providers.
