摘　　要：目的评估MRI平扫对膝关节髌内侧滑膜皱襞综合征(mediopatellar plica syndrome,MPS)的诊断价值。方法回顾性分析84例行关节镜检查的膝关节MRI平扫及MR关节造影资料,分别统一MPS的磁共振及关节镜诊断标准,评估MRI平扫及MR关节造影图像中MPS的存在与否与分型,并与关节镜结果进行对比。结果 84例膝关节中,关节镜发现有19例存在MPS,MRI平扫发现18例(C型14例,D型4例),MR关节造影发现21例(C型16例,D型5例)。MRI平扫诊断MPS的敏感度(94.4%)和特异度(98.5%)较高,MR关节腔造影诊断MPS的敏感度(100%)和特异度(96.9%)亦较高。MRI平扫和MR关节造影与关节镜结果的一致性较好(kappa>0.75)。结论 MRI平扫对MPS的诊断及分型均具有重要价值,在诊断MPS时MRI平扫在一定程度上可以替代MR关节造影。Objective To evaluate the value of MR imaging on mediopatellar plica syndrome （MPS） of knee joint. Methods The non-enhanced MR imaging and MRI arthrography of eighty-four knees joint underwent arthroscopy were analyzed retrospectively. The diagnostic criteria of MPS of MRI and arthrography were confirmed respectively. The existence and type （ if existed） of MPS were evaluated on non-enhanced MR imaging and MRI arthrography imaging, and compared with those of arthroscopy. Results In 84 knees, MPS was found in 19 ones in arthroscopy with 18 （14 type C, 4 type D） in non-enhanced MR imaging and 21 （16 type C, 5 type D） in MRI arthrography. The sensitivity and specificity were high in both non-enhanced MR imaging and MRI arthrography （94.4% and 98.5% , 100% and 96.9% ;respectively）. Non-enhanced MR imaging and MRI arthrography had good agreement with arthroscopy （ kappa 〉 0.75 ）. Conclusion Non-enhanced MR imaging had great value in the diagnosis and classification of MPS. MRI arthrography can be replaced by non-enhanced MR imaging in the diagnosis of MPS to a certain extant.
