Feb

Overview

DEXA measures bone mineral density to assess fracture risk. It is the standard test for osteoporosis diagnosis. It is quick and involves low radiation dose.

Clinical Use

DEXA guides treatment decisions for bone health. It monitors response to therapy over time. Results are interpreted using standardized scores.

Technique Considerations

Patient positioning and calibration affect accuracy. Quality control ensures reproducible results. Interpretation considers clinical risk factors.

Future Trends

New methods aim to assess bone quality beyond density. Research explores trabecular assessment and finite element analysis. These advances may improve fracture risk prediction.

DEXA Bone Densitometry

Feb

Overview

DEXA measures bone mineral density at the spine and hip to assess osteoporosis risk and monitor therapy.

Technique

Dual energy acquisition separates bone from soft tissue. Standardized positioning and calibration ensure reproducible results.

Clinical Uses

Diagnosis of osteoporosis fracture risk assessment and monitoring response to bone directed therapy.

Limitations and Safety

Limited to bone density assessment. Artifacts from hardware or degenerative change can affect accuracy.
