摘　　要：目的:探讨3.0T MR多片技术双反转恢复序列(MS-DIR)对膝关节滑膜病变的诊断价值。方法:搜集经关节镜及病理证实的膝关节滑膜病变患者38例,回顾性对比分析其术前膝关节增强扫描序列(T1WI-FS-CE)与MS-DIR序列影像资料,评估T1WI-FS-CE与MS-DIR序列图像在均匀度、病变显示、滑膜厚度测量值等方面的一致性。结果:38例膝关节滑膜病变MS-DIR序列均表现为稍高-高信号;MS-DIR与T1WI-FS-CE序列图像在均匀度方面差异有统计学意义(Z=-7.803,P<0.001),在滑膜显示程度及图像整体质量上差异无统计学意义(P>0.05);两种序列对图像主观评价有较高的一致性(K值分别为0.684、0.841);两种序列相同层面、位置的滑膜厚度测量值有较好的一致性(<95%LoA)。结论:3.0T MR MS-DIR序列与对比增强序列在膝关节滑膜病变的整体图像质量、细微结构显示、滑膜厚度测量方面有较高的一致性,MS-DIR序列结合常规序列扫描可用于膝关节滑膜病变的筛查与治疗后评估。Objective:To investigate the diagnostic value of multiple slice-double inversion recovery(MS-DIR)on 3.0T MRI for synovial lesions of knee joint.Methods:A total of 38 patients with synovial lesions of knee joint confirmed by arthroscopy and pathology were collected,and the imaging data of preoperative knee enhanced scan sequence(T1WI-FS-CE)and MS-DIR sequence were analyzed retrospectively,to evaluate the consistency of T1W-FS-CE and MS-DIR in terms of uniformity,lesion display and synovial thickness measurement.Results:The MS-DIR sequence of 38 cases of synovial lesions of knee joint showed slightly high-high signal.MS-DIR and T1WI-FS-CE sequences showed statistically significant differences in the uniformity(Z=-7.803,P<0.001),but no statistically significant differences in synovial display degree and overall image quality(P>0.05).The two sequences showed high consistency in the subjective evaluation of images(K=0.684 and 0.841,respectively).The results of synovial thickness measurement at the same level and position of the two sequences were in good agreement(<95%LoA).Conclusion:3.0T MR MS-DIR sequence and contrast-enhanced sequence have high consistency in the overall image quality,fine structures display,and synovial thickness measurement of synovial lesions of knee joint.Combined with conventional sequence scan,MS-DIR sequence can be used for screening and post-treatment evaluation of synovial lesions of knee joint.
