摘要

This chapter reviews the available technologies commonly used for measuring bone mineral density: dual-energy x-ray absorptiometry (DEXA) and quantitative computed tomography (qCT). Quality and patient safety associated with these modalities are discussed, highlighting relevant quality assurance and quality control practices. Regulatory guidelines governing the use of these modalities are reviewed. Emerging AI-based tools for fracture diagnosis are also reviewed, along with ongoing efforts to improve quality and patient safety in clinical practice.
