For these reasons, SSI has attracted attention from technical and clinical researchers for the diagnosis of liver fibrosis, breast tumors, and thyroid lesions, as well as the assessment of placental elasticity in preeclampsia. Supersonic shear wave imaging (SSI) is a dynamic method with proven superiority in the evaluation of the mechanical properties of tissue due to the high-resolution images it provides of superficial and deep tissues, and because it provides local quantitative elastic data in an ultrafast way. Muscle fibers not only transmit force to tendons, but also interact with them due to their mechanical properties.

The muscle-tendon unit (MTU) involves the connection between the muscles and tendons, through which contractile forces are generated and transmitted.
