Abstract
The amount of intraosseous fat in the proximal femur is exponentially dependent on a coefficient that has been formulated from the bone attenuation curve using 241Am bone mineral absorptiometry of the distal radius in the same subject. The coefficient enables estimation of the 133Xe partition coefficient between blood and nonhematopoietic tissues of bone. Bone circulation can then be measured in the proximal femur in diseases that affect the whole skeleton.
摘要
股骨近端骨内脂肪量呈指数依赖于一个系数，该系数由同一受试者桡骨远端使用镅-241骨矿吸收测定法的骨衰减曲线得出。该系数能够估算133氙在血液与骨非造血组织之间的分配系数。进而可以在影响整个骨骼的疾病中测量股骨近端的骨循环。
