Quantitative digitized radiography uses low-energy photons to measure bone density with precision not available in older techniques. Using this method, lumbar spine density was evaluated in 12 women before and after 6 months of therapy with LA. A 2.9% decrement in mean bone density was documented. The reproducibility of quantitative digitized radiography suggests that this small degree of bone mineral loss is a real phenomenon and not an artifact of measurement. The clinical significance of this degree of bone mineral loss has yet to be established.
定量数字化放射成像使用低能光子来精确测量骨密度，这是早期技术所无法做到的。采用这种方法，对12名女性在接受亮丙瑞林治疗6个月前后的腰椎骨密度进行了评估。结果显示平均骨密度下降了2.9%。定量数字化放射成像的可重复性表明，这种程度较小的骨矿物质流失是一种真实现象，而非测量假象。这种程度的骨矿物质流失的临床意义尚待确定。
