We
acquired high-resolution proton and sodium images at 7T using dual-tuned
1H/23Na coil and 3D ultra-short-echo spiral trajectory sequence and
quantitatively analyzed the distribution of sodium signals at different
compartments of the knee cartilage. The images demonstrated excellent SNR and
resolution of proton and sodium in vivo that allowed us to perform
quantitative analysis of the cartilage morphology as well as characterization
of cartilage quality.
