摘要
回顾性分析半月板撕裂的ＭＲＩ表现，评价ＭＲＩ在诊断半月板撕裂中的作用和价值。材料与方法，对４０例半月板损伤的ＭＲＩ资料和手术的所见所对照分析。ＭＲＩ半月板内异常高信号为Ⅰ－Ⅲ度。结果在４０例８０个半月板中有４８个半月板呈Ⅰ－Ⅲ度ＭＲＩ表现，有５个半月板表现不典型，以手术结果为标准。
Purpose: To retrospectively ana1yse the MRI findings of meniscal tear of the knee and evaluate the role of MRI in di-agnosing menisca1 tear. Materials and Methods: MRI of 40 cases clinically suspected meniscal injuries was compared with operation.The abnormal high intensities within the menisci on MRI were classified into grade Ⅰ~Ⅱ. Results: 40 cases of 80 menisci had MRIfindings of Ⅰ~ Ⅱ and five menisci showed atypical MRI findings, using the results of operation as criterion, the sesitivity, speclficityand accuracy of MRI in diagnosing injuries of menisci were respectively 94. 3 %, 93. 3 % and 93. 8 %. A negative predictive value of95. 5 % was found. Conclusion: MRI was important in diagnosing meniscal tear.
