DEXA

21. Dual-energy x-ray absorptiometry (DEXA) is the technique of choice in the assessment of bone mineral density (BMD)
21. Dual-energy X-ray absorptiometry (DXA) is used  for diagnosis of osteoporosis, and for monitoring changes in BMD over time.

21. DEXA is a quick method that is:

5. Accurate (exact measurement of BMD)
5. Precise (reproducible),
5. Flexible (different regions can be scanned)
5. Performed with a low radiation dose

Procedural steps in DEXA

21. Procedural steps in DEXA scanning can be broken down into:
21. Scan acquisition
21. Analysis
21. Interpretation
21. Reporting

Image Acquisition

21. Areas Scanned

5. Lumbar spine(vertebral bodies L1–L4)
5. Proximal femur
5. Forearm(the distal one third ,33% radius)
