Quantifying sodium in the human wrist in vivo by using MR imaging.
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.
