The tendon tissues in the knee are characterized by a short T₂ relaxation time due to their fibrous structure and their high collagen content. Conventional MRI technique are unable to pick up such fast decaying signal, thus new methods and sequences such as UTE have been introduced. In this work a 3D UTE sequences was applied to quantify the T₂* and T₁ relaxation parameters for the patellar and quadriceps tendons.
