A prototype 1.5 T receive-only 3-element multi-directional MSK phased array wrist coil that is capable to maintain its performance even when it is angulated from +/-55 to B0 was constructed and successfully tested. The ability to angulate the coil through a wide range of angles, allows positioning the coil in the center of the DSV with the possibility for relaxed overhead positioning of the wrist through horizontal flexion of the elbow. With this setup, high quality wrist images can be acquired and patient comfort can be achieved.
