Double echo steady state (DESS) imaging allows acquisition of two MR images with different contrasts from FID and echo images. In this study, we explored the feasibility and efficacy of 3D UTE Cones-based DESS (3D UTE-Cones-DESS) imaging of short T2 tissues in the knee joint. In ex vivo study of four cadaveric knees and in vivo study of three healthy volunteers, the UTE-Cones-DESS sequence provided high contrast imaging of the osteochondral junction (OCJ), the menisci, and other short T2 tissues, as well as T2 maps, under a total scan time of three minutes.
