影像学领域中的骨密度 (ｂｏｎｅｍｉｎ ｅｒａｌｄｅｎｓｉｔｙ ;ＢＭＤ)是指单位骨体积或面积的平均骨矿物质含量。它是反映骨量的重要指标 ,通过对骨密度的测定 ,可以及时了解骨质的变化 ,有利于对骨相关疾病早期诊断、判断治疗、推断愈后。靠肉眼观察Ｘ线片来估计骨密度的
Bone mineral density (BMD) in the field of imaging refers to the average bone mineral content per unit bone volume or area. It is an important indicator of bone mass. Through the measurement of bone density, we can know the change of bone in time, which is good for early diagnosis, judgment and treatment of bone-related diseases. By the naked eye X-ray film to estimate the bone mineral density
