Standard magnetic resonance imaging protocols fail to generate sufficient positive contrast for the direct imaging of bone. This study demonstrates the use of zero echo time (ZTE) imaging of the appendicular skeleton. Knee, shoulder, ankle, and wrist joints were imaged and scan parameters were varied between subjects to optimize acquisition of joints of interest. ZTE images permitted the visualization of fine tendinous structures in addition to bone. ZTE may prove useful when concurrent imaging of tendon and bone is required or when bone imaging is necessary but radiation dose is undesirable, due to patient age or anatomy.
