Application of MSUS in ligaments in sports injuries

MSUS plays an important role in tendon injury assessment. MRI is able to detect the integrity of the tendon structure, while MSUS helps to image intranasal vein pathologies. Changes in echogenicity, thickness, shape, contour, or blood flow suggest possible tendinopathy. Fluid around the tendon or tendon sheath can also be easily detected on ultrasound. When scanning the musculoskeletal system, especially tendons, it is important to minimize anisotropy by keeping the ultrasound beam from the transducer perpendicular to the desired site for maximum signal reflection. Improper tilting or tipping of the transducer strip may cause more refraction than reflection and thus reduce the echogenicity of target structures. The lesion may be falsely graded as hypoechoic or even anechoic. Such technical problems may lead to misdiagnosis of tendinopathy or normal tendon rupture. By using color or power doppler techniques, the vessels inside or around the bone can be easily identified without additional contrast material. Increased vascularity in the injured tendon is consistent with the post-injury inflammatory process. The degree of muscularization of the muscles may be proportional to the intensity of the inflammatory pain in the hyperemic tendon.
