Area of Science:

  • Radiology
  • Rheumatology
  • Medical Imaging

Background:

  • Bone loss is a significant complication in rheumatoid disease.
  • Densitometric techniques for measuring bone loss have steadily improved.
  • Assessing bone loss in rheumatoid disease requires accurate and sensitive methods.

Purpose of the Study:

  • To review advancements in densitometric techniques, focusing on the latest generation of DXA scanners.
  • To evaluate the suitability of the lumbar spine, femur, and hand for densitometric measurement of bone loss in rheumatoid disease.
  • To assess the clinical utility of improved hand scanning techniques using DXA for detecting juxta-articular bone loss.

Main Methods:

  • Review of advancements in densitometric techniques.
  • Assessment of dual-energy X-ray absorptiometry (DXA) scanning at the lumbar spine, femur, and hand.

Related Experiment Videos

  • Evaluation of juxta-articular bone loss detection using enhanced resolution DXA scanners.

    • Main Results:

    • The newest generation of DXA scanners offers enhanced resolution.
    • Improved hand scanning techniques with DXA enhance the detection of juxta-articular bone loss.
    • DXA scanning can detect bone loss even when systemic features are not evident.

    Conclusions:

    • DXA scanning of the hand is a potentially useful modality for monitoring early rheumatoid disease.
    • Enhanced resolution DXA scanners improve the ability to detect subtle bone loss.
    • Hand DXA may be valuable for early detection and monitoring of rheumatoid disease progression.
