Abstract

The technique of computer-assisted transverse axial tomography has been exploited by minor modification of an E.M.I. brain scanner to determine measurements of bone-mineral content in distal radius and ulna. Such measurements are possible independent of adipose tissue subcutaneously or within the bone and irrespective of bony contour. Preliminary studies suggest that the accuracy and precision justify further longitudinal studies in the exploration of trabecular bone within vertebral bodies by whole-body computer-assisted tomography.

摘要

通过对EMI脑部扫描仪进行微小改进，利用计算机辅助横向轴向断层扫描技术来测定桡骨远端和尺骨的骨矿物质含量。这样的测量不受皮下或骨内脂肪组织的影响，也与骨轮廓无关。初步研究表明，其准确性和精确性使得通过全身计算机辅助断层扫描对椎体小梁骨进行进一步纵向研究具有合理性。
