Whole-Body Dual-Energy X-Ray Absorptiometry (DXA) for Skeletal Musculoskeletal System Evaluation
This low-radiation, non-contrast dual-energy X-ray absorptiometry exam uses two precisely calibrated X-ray beams to quantify bone mineral density across the entire human skeleton, while also measuring lean muscle mass and fat distribution across all major musculoskeletal structures including bones, joints, ligaments, tendons, muscles, and articular cartilage. It serves as the gold standard diagnostic tool for detecting osteopenia and osteoporosis, assessing fracture risk in patients with chronic musculoskeletal conditions, and tracking longitudinal changes in bone and soft tissue composition for individuals with autoimmune diseases, endocrine disorders, or a history of long-term corticosteroid use.
This low-radiation whole-body DXA scan measures skeletal bone mineral density and evaluates all major musculoskeletal structures including bones, joints, ligaments, tendons, muscles, and articular cartilage to diagnose bone density disorders and assess fracture risk.

Understanding DEXA Scan of skeleton
Dual-energy X-ray Absorptiometry provides detailed visualization of skeleton. The procedure uses controlled radiation to create precise images with excellent anatomical detail.
Clinical Indications
This imaging detects fractures and dislocations, evaluates joint arthropathy, assesses soft tissue injuries, and identifies bone lesions.
What to Expect
The procedure typically takes 10 minutes. The examination is painless and non-invasive.
How to read the report
- Results reviewed by board-certified radiologist.
- Report transmitted to referring physician.
