This study was performed to visualize the entheses of the foot at 3T and 11.7T utilizing 2D and 3D images. The contrast and quality of the MR images obtained have never been shown before. These include the Achilles tendon, tibialis posterior tendon at the level of the medial malleolus and at the navicular insertion, central slip of the extensor tendon of the toes, collateral ligaments, and plantar plate. We also demonstrate collagen fiber structure which has not previously been described, including perpendicular fibers at functional entheses.
