Dual energy X-ray absorptiometry: guidelines under revision

The main focus of this paper lies on the evaluation of the quality of the published guidelines on dual energy X-ray absorptiometry (DXA) for adults using the AGREE II tool. DXA is the most common technique to measure bone mineral density (BMD).

Teaching points:

  • Three of four guidelines on DXA had a high quality level (<60%).
  • Scope/purpose had the highest score (86.8 ± 3.7%).
  • Editorial Independence had the lowest score (54.7 ± 12.5%).
  • Interobserver agreement ranged from fair (0.230) to good (0.702).


Dual energy X-ray absorptiometry (DXA) is the most widely used technique to measure bone mineral density (BMD). Appropriate and accurate use of DXA is of great importance, and several guidelines have been developed in the last years. Our aim was to evaluate the quality of published guidelines on DXA for adults.
