Quantitative CT of vertebral trabecular bone is established as a sensitive technique for assessing bone mineral mass in the axial skeleton. We have adapted this technique for use in a standard third generation whole body CT scanner without requiring any extra equipment or software. By utilizing a maximum area of interest in the vertebral trabecular bone, we have developed a method of bone mineral content estimation that is precise, accurate, and a more representative measurement of the vertebral trabecular bone. Measurements in 70 healthy postmenopausal women have shown that our results compare favourably with those from other centres. Our findings demonstrate that the technique of quantitative CT of bone can be adapted for advanced CT scanners without any modifications being required. This should lead to an increase in availability of such measurements, resulting in improvements both in the diagnosis of metabolic bone diseases and in the efficacy of treatment.
定量CT测量椎体小梁骨已成为评估中轴骨骨矿物质含量的一项敏感技术。我们已将此技术应用于标准第三代全身CT扫描仪，无需任何额外设备或软件。通过利用椎体小梁骨的最大感兴趣区，我们开发了一种骨矿物质含量估算方法，该方法精确、准确，是对椎体小梁骨更具代表性的测量。对70名健康绝经后女性的测量结果表明，我们的结果与其他中心的结果相比具有优势。我们的研究结果表明，骨定量CT技术可适用于先进的CT扫描仪，无需进行任何修改。这将增加此类测量的可及性，从而改善代谢性骨病的诊断和治疗效果。
