Abstract

The authors quantified sodium content in the wrist joints of six healthy volunteers with no known history of arthritis or pain. Average sodium concentrations ranged from 115 to 150 mmol/L in noncartilaginous regions and from 200 to 210 mmol/L in cartilaginous regions. The feasibility of quantifying sodium in vivo was demonstrated. This method has potential applications in monitoring the integrity of cartilaginous tissue in vivo.

摘要

作者对六名无关节炎或疼痛病史的健康志愿者的腕关节中的钠含量进行了量化。非软骨区域的平均钠浓度范围为115至150 mmol/L，软骨区域为200至210 mmol/L。证明了体内钠定量的可行性。该方法在监测体内软骨组织完整性方面具有潜在应用。
