骨质疏松是世界上最常见的骨代谢病 ,累及许多人的健康 ,造成巨大的医疗负担。常累及脊柱 ,导致椎体骨折变形和随之而来的疼痛和残疾。迫切需要一种准确的方法预测骨折危险性 ,并对高危人群进行检测和治疗。骨密度 (ＢＭＤ)是预测骨折危险性的主要指标 ,而且可以被精确地测量。 Osteoporosis is the most common bone metabolism in the world, affecting many people’s health and causing a huge medical burden. Often involving the spine, resulting in vertebral fracture deformation and the accompanying pain and disability.
