摘要:目的:基于循证医学理念,采用Meta分析法定量评价低场磁共振(MRI)对膝关节软骨损伤评估的准确性。方法:检索Cochrane图书馆、Pubmed、Medline及Elsevier以及中国期刊网(CNKI),在1990-2013年间公开发表的相关中文及英文文献,对纳入文献进行质量评价。结果:低场MRI对膝关节软骨损伤诊断的汇总灵敏度、特异度和SROC曲线下面积分别为86%、84%和89.8%,Q*值为0.829。结论:低场MRI诊断膝关节软骨损伤有较高的诊断价值,为临床进一步诊断与治疗提供可靠的依据。

Abstract: Objective: Evaluation the accuracy of low field Magnetic Resonance Image (MRI) in the assessing of cartilage defects of the knee through Meta-analysis method. Methods: Retrieve the Chinese and English paper recorded by Cochrane Library, Pub med, Medline and Elsevier and China national knowledge index (CNKI), which was published between 1990 and 2013. According to the corresponding inclusion and exclusion criteria. Results: The results showed that the sensitivity, specificity and SROC curve under the area of low-field MRI in the diagnosis of knee cartilage defects was 86%, 84% and 89.8%, respectively. In addition, the Q * index was 0.829. Conclusion: Low field MRI in the diagnosis of knee joint cartilage injury has high diagnostic value, it can be a reliable basis for clinical diagnosis and treatment of further.

隨着我国人口的老龄化,膝关节软骨损伤的病例逐步增多,关节软骨损伤可以导致关节疼痛、积液和功能障碍,严重影响患者的生活质量。磁共振成像(MRI)作为一种无创评估手段在关节软骨损伤诊断中的应用最为普遍,对全层关节软骨损伤的评估较为准确[1],由于不同国家、不同地区、生活方式及医疗经济条件的差异,低场MRI目前在基层医院广泛应用于膝关节疾病的诊断中,但它们的诊断价值文献报道不一,单个临床试验样本量有限,在不同程度上容易受各种因素的干扰而产生偏倚[2]。把多个目的相同,设计方案相同或类似的试验集中起来,进行综合汇总分析,得到一个更真实、更精确的综合指标,用来指导临床实践。

1 材料与方法

1.1 一般资料

检索的数据库包括中国期刊网(CNKI)、Cochrane图书馆、Pubmed数据库、Medline数据库、Elsevier数据库。文献检索词:英文检索词:(knee cartilage defects OR articular genu OR knee joint cartilage)AND low field magnetic resonance image AND arthroscope中文检索词:膝关节软骨损伤OR膝关节软骨OR膝关节AND低磁场核磁共振AND关节镜。

检索文献发表年限为1990年1 月至2013 年12 月,文献语种定义为中文和英文。

我们最终纳入11篇文献(见表1),为低场MR诊断膝关节软骨损伤的研究。

1.2 统计学方法

采用Stata12软件和meta-disc1.4软件对纳入文献行统计学处理,包括异质性检验,计算灵敏度和特异度及其95%可信区间,绘制受试者工作特征曲线(SROC)并计算曲线下面积。

2 结果

对低场强核磁共振诊断膝关节软骨损伤分析后,Q=12.50,P>0.10,I2=0.28,说明纳入的病例有一定的异质性,但异质性不明显,可以认为不同研究结果组内之间是同质的,研究结果的不同是由抽样误差造成的,应采用固定效应模型进行Meta分析。

低场MRI对膝关节软骨缺损诊断的汇总灵敏度、特异度和SROC曲线下面积分别为86%(95%CI:84%-89%)、84%(95%CI:81%-87%)和89.8%,Q*值为0.829。

3 讨论

本次研究低场MRI软骨缺损评估的汇总灵敏度、特异度、及SROC曲线下面积为86%(95%CI:84%-89%)、84%(95%CI:81%-87%)和89.8%,Q*值为0.829。分析结果稳定,可信度较高。我们的研究可以为临床医生提供更科学、更精确的诊断和决策依据。结果表明,低场核磁共振诊断膝关节软骨损伤有较高的统计学价值。
