Xu YiGu HongDepartment of Radiology,Jiangmen Wuyi Hospital of TCM,Sixth Affiliated Hospital JinanUniversity Medical College,Guangdong,529000  
Purpose:To study the value of low field MR imaging in the diagnosis of the trauma of the knee joints.Materials and Methods:The MRI findings of trauma of the 104 knee joints of 84 cases confirmed surgically or arthroscipically were retrospectively analyzed.Results:of 60 injuries of meniscus,degree 1~2 in 42,degree 3 in 18 the coincident rate of degree 3 is 79%(18/22);of 23 injuries of anterior cruciate ligament(ACL),degree 1~2 in 14,degree 3 in 9 the coincident rate of degree 3 is 77%(7/9);of 19 injuries of posterior cruciate ligament(PCL),degree 1~2 in 12,degree 3 in 7 the coincident rate of degree 3 is 85%(6/7);of 18 injuries of medial collateral ligament(MCL),degree 1~2 in 14,degree 3 in 4 the coincident rate of degree 3 is 50%(2/4);of 5 injuries of outboard collateral ligament(OCL).Conclusion:low field MRI could clearly demonstrate the lesions in the knee joints,including the injuries of meniscus,ligaments articular cartilage,the contusion of bone and peripheral parenchyma and hydrarthrosis.Furthermore low field MRI could grade the injuries of meniscus,ligaments,articular cartiolge.The diagnosis accuracy of MR imaging was superior to that of radiography.MR imaging could accruately demonstrate the features and severity of the trauma of the knee joints.MRI is an ideal and noninvasive technique in the diagnosis of the trauma of the knee joints and has important value in therapy planning.
