Abstract
Measurement of bone strontium (Sr) is vital to determining the effectiveness of Sr supplementation, which is commonly used for the treatment of osteoporosis. Previous technology uses radioisotope sources and bulky equipment to measure bone Sr. This study demonstrates the effectiveness of portable X-ray fluorescence (XRF) for bone Sr measurement and validates it using data from a population of 238 children. We identified correlations between bone Sr and age in our participants.
摘要
测量骨骼中的锶（Sr）对于评估锶补充剂的有效性至关重要，锶补充剂常用于治疗骨质疏松症。以往的技术使用放射性同位素源和大型设备来测量骨骼中的 Sr。本研究展示了便携式 X 射线荧光（XRF）技术在骨骼 Sr 测量中的有效性，并使用 238 名儿童的数据进行了验证。我们在研究对象中发现了骨骼 Sr 与年龄之间的相关性。
