Aim of this study was to compare the quantitative and qualitative performance of a routine 8-channel knee coil at 3T and a new 28-channel knee coil at 7T. Compared to an optimized 3T protocol, at 7T, i)the resolution was increased whereas keeping the same examination time and ii)the examination time was reduced whereas keeping the spatial resolution the same.
