Application of MRI in the Prevention of Sports Injuries in Physical Education Teaching

In order to explore the situation of ankle sports injury in physical education, the author proposed the application method of MRI in sports injury prevention in physical education. In a retrospective analysis of 28 patients with clinically diagnosed ankle injuries, taking ankle arthroscopy/incision as the standard, the sensitivity and diagnostic value of MRI examination for ankle sports injury were analyzed statistically. The result shows that 6 cases of ankle fracture were correctly diagnosed by MRI, and the diagnostic sensitivity for bone marrow contusion and edema was 100%. Among the 19 cases of clinically diagnosed ankle ligament injury, 16 cases were diagnosed by MRI, and the overall sensitivity was 84%. Of the 8 cases of calcaneofibular ligament injury, 6 cases were correctly diagnosed by MRI, with a sensitivity of 75%. . 3.0 T MRI examination has high sensitivity for ligament, tendon, and cartilage injury, which can well show ankle joint injury and provide an objective basis for early clinical treatment and rehabilitation.
