This in vivo study on 10 healthy subjects compares the performance of a 28 channel phased array coil and a circularly polarized coil for morphologic magnetic resonance imaging and T2 mapping of knee cartilage at 7 Tesla. Signal-to-noise ratio and contrast-to-noise ratio are higher with the 28 channel coil, favoring its use for future studies of osteoarthritis or other knee pathology.
