[High Resolution Magnetic Resonance Tomography and Ultrasound Imaging of the Achilles Tendon].

Increasing sporting activities of high-ranking athletes as well as of the general population have led to a higher number of lesions of the Achilles tendon. Radiological investigations of this tendon are requested more often and the resolution of MR and ultrasound images has been improved significantly. Intratendinous lesions can be detected and may be differentiated from normal collagen fibers.
