| Technique . | Site . | Comments . |
|---|---|---|
Single (or dual) energy X-ray absorptiometry | Forearm and heel | Inexpensive, precise, uses low doses of radiation, measures sites unresponsive to therapy |
Dual-energy X-ray absorptiometry | Lumbar spine | Fairly expensive, precise, uses low doses of radiation, measures site responsive to therapy, needs skilled operator, subject to artefacts (spondylosis) |
Proximal femur | Fairly expensive, less precise, uses low doses of radiation, measures site best for fracture prediction, needs skilled operator | |
Total body | Expensive, precise, uses low doses of radiation, measures sites unresponsive to therapy, needs skilled operator, allows assessment of body composition | |
Quantitative computed tomography | Spine | Expensive, less precise, uses high doses of radiation, measures sites responsive to therapy, needs skilled operator, allows assessment of trabecular bone alone |
Forearm and ankle | Inexpensive, precise, uses low doses of radiation, measures sites unresponsive to therapy, does not need skilled operator | |
Ultrasonometry | Heel, fingers, etc. | Inexpensive, less precise, uses no radiation, measures sites unresponsive to therapy, does not need skilled operator, fairly portable |
