The compact MRI for bone density measurements is a small-size MRI specially designed for the calcaneus by using a small permanent magnet. This system can measure a trabecular bone volume fraction (TBVF) for a clearly defined 3D region. The correlation coefficient (R(2)) between TBVF and QUS-SOS, and that between TBVF and DXA were about 0.29 for about 100 female subjects, and about 0.38 for about 20 subjects, respectively. This system will be especially useful for bone density measurements for children and young people.
用于骨密度测量的紧凑型磁共振成像仪是一种小型磁共振成像设备,它采用小型永久磁铁,专门为跟骨设计。该系统能够测量一个明确界定的三维区域的骨小梁体积分数(TBVF)。对于约100名女性受试者,TBVF与定量超声声速(QUS-SOS)之间的相关系数(R(2))约为0.29,对于约20名受试者,TBVF与双能X线吸收法(DXA)之间的相关系数约为0.38。该系统对于儿童和年轻人的骨密度测量将特别有用。
