第1期·短篇论著·关于膝关节弥漫性滑膜病变的MRI诊断及鉴别诊断准确率评价分析柴晓昕（乌鲁木齐市友谊医院放射科乌鲁木齐830049）摘要：目的探究膝关节弥漫性滑膜病变的MRI诊断及鉴别诊断准确率。方法选择疑似膝关节弥漫性滑膜病变患者作为此次研究的主要对象，收治时间在2018年5月-2020年10月，对所有患者均实施MRI诊断及鉴别，后分析诊断准确率。结果100例疑似膝关节弥漫性滑膜病变患者，经确诊的有95例，骨性关节炎继发性滑膜炎有44例，所占比97.78%、滑膜软骨瘤病有20例，所占比为100%、色素沉着绒毛结节性滑膜炎有9例，所占比为90%、痛风性关节炎滑膜炎有8例，所占比为100%、类风湿性关节炎滑膜增生有8例，所占比为100%、膝关节结核累及滑膜有4例，所占比为100%；MRI诊断正确率97.89%（93/95）。MRI诊断的敏感度为97.89%，特异度为100%，漏诊率为2.11%，误诊率为0%。结论MRI诊断在膝关节弥漫性滑膜病变中效果显著，且诊断准确率较高，能够为后期治疗提供有利参考依据，值得研究和推广。关键词：膝关节弥漫性滑膜病变；MRI诊断；鉴别；诊断准确率中图分类号：R235文献标识码：A文章编号：1001—5183（2023）01—83—03EvaluationandanalysisofMRIdiagnosisanddifferentialdiagnosisaccuracyofdiffusesynoviallesionsofkneejointCHAIXiaoxin（DepartmentofRadiology,FriendshipHospitalofUrumqi,Urumqi,830049,China）Abstract：ObjectiveToexploretheaccuracyofMRIdiagnosisanddifferentialdiagnosisofdiffusesynoviallesionsofkneejoint.MethodsPatientswithsuspecteddiffusesynoviallesionsofthekneejointwereselectedasthemainobjectsofthisstudy.ThetimeoftreatmentwasfromMay2018toOctober2020.AllpatientswerediagnosedanddifferentiatedbyMRI,andthediagnosticaccuracywasanalyzed.ResultsAmongthe100casesofsuspecteddiffusesynoviallesionsofkneejoint,95caseswereconfirmed;44casesweresecondarysynovitisofosteoarthritis,accountingfor97.78%;20casesweresynovialchondromatosis,accountingfor100.0%;9caseswerepigmentedvillonodularsynovitis,accountingfor90.00%;8casesweregoutyarthritissynovitis,accountingfor100.0%;Thesynovitisofrheumatoidarthritisincreased,accountingfor100.0%.ThecorrectrateofMRIdiagnosiswas97.89%（93/95）.Thesensitivity,specificity,misseddiagnosisandmisdiagnosisofMRIwere97.89%,100.0%,2...
