Three-dimensional radial zero echo time (ZTE) imaging enables efficient direct MRI of tissues with rapid transverse relaxation. The technique was employed for imaging of a lamb joint sample at 4.7 T. ZTE images effectively suppressed signals from tissues with long-T2 water, such as muscle or articular spaces, and fat. Primarily short-T2 tissues were visible, such as bone and tendon. The MR image intensity of bone showed strong similarity with bone density imaged with micro-computed tomography.
