BMD

Bone mineral density: a measurement result, not a standalone diagnosis.

これは何か

BMD estimates how much mineral is present in a measured bone area. DXA reports often use BMD to calculate T-scores or Z-scores.[1,2]

なぜ重要か

Lower BMD can be associated with higher fracture risk, but bone quality, falls, disease context, and prior fractures also matter.[1]

どの判断に影響するか

  • A low BMD result can support low bone mass or osteoporosis classification in the right adult population.[1,3]
  • High density is not automatically strong bone; osteopetrosis is one counterexample.[4]

解釈上の注意

  • Do not read BMD without age, sex, skeletal site, instrument, fracture history, and clinical context.[3]
