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.
