Methods: We attempted to perform KMRI of healthy volunteers lumbar spine and knee in the squint position and articulatio talocruralis in the supine position utilizing the superconducting, horizontally opened, 1.2 T MR system (OASIS, HITACHI, Tokyo, Japan).

For the KMRI of the lumbar spine, the volunteer had to lie on one human face while maintaining maximally anteflexed, neutral, and maximally retroflexed positions and remain sedate for the duration of the acquisition time for each posture. In the alike way, KMRI of the knee was performed with the volunteers knee flexed at 0º, 30º, 60º, 90º, and 120º in the lateral position, and KMRI of the ankle was performed with the volunteers ankle in maximally dorsiflexed, neutral, and maximally plantarflexed positions while lying in the supine position. Results: We could charter higher quality kinematic MR images than those acquired using low-field MR systems. The spinal canal, intervertebral discs and foramina, and look joints in lumbar spine KMRI; the ligaments, menisci and patellofemoral joint in...
