The aim of the current study was to investigate the depth-wise variation of relaxivity in human femoral head articular cartilage using anionic and nonionic contrast agent. The relaxivities were nearly identical, with mean value of 3.8 1/mM/s for both contrast agents, showing similar values through the entire cartilage depth.
