摘　　要：目的:探讨多回波合并梯度回波成像(MEGRE)序列在早期膝关节软骨损伤中的诊断价值。方法:回顾性分析2020年9月~2022年12月在本院进行治疗的129例早期膝关节软骨损伤患者一般临床资料,筛选出先后行MRI MEGRE序列、MRI常规序列的76例患者进行研究,记录两种不同序列对膝关节软骨损伤的诊断情况,并以关节镜结果为金标准,探讨MRI MEGRE序列、MRI常规序列对早期膝关节软骨损伤的诊断价值。结果:MEGRE序列及常规序列图像评分中均无1分、2分者,其3分、4分、5分占比情况比较有显著差异(P<0.05);在MRI上对髌骨、胫骨内外侧平台、股骨内外侧踝、股骨滑车6个关节面关节软骨进行评估,共有456个关节软骨,关节镜结果检出0级、Ⅰ级、Ⅱ级、Ⅲ级、Ⅳ级各54例、96例、147例、82例、77例;MRI MEGRE序列检测出0级、Ⅰ级、Ⅱ级、Ⅲ级、Ⅳ级各54例、96例、150例、82例、74例;常规序列检测出0级、Ⅰ级、Ⅱ级、Ⅲ级、Ⅳ级各55例、93例、147例、83例、78例;MRI MEGRE序列在膝关节软骨损伤分级诊断中的敏感度明显高于常规序列(P<0.05)。结论:在早期膝关节软骨损伤诊断中,MRI MEGRE序列较常规序列具有更高质量的影像学图像,且在膝关节软骨损伤分级中,具有更高的诊断效能。Objective:To investigate the diagnostic value of multiple echo combined with gradient echo imaging(MEGRE)sequence in early knee cartilage injury.Methods:The general clinical data of 129 patients with early knee cartilage injury treated in our hospital from September 2020 to December 2022 were retrospectively analyzed,and 76 patients who received MRI MEGRE sequence and MRI routine sequence were selected for study.The diagnosis of knee cartilage injury with two different sequences was recorded.Taking arthroscopic results as the gold standard,the diagnostic value of MRI MEGRE sequence and conventional MRI sequence in early knee cartilage injury was discussed.Results:There were no scores of 1 or 2 in MEGRE sequence and conventional sequence images,and there were significant differences in the proportions of 3,4 and 5 points(P<0.05).6 articular surfaces,namely patella,medial and lateral tibial plateau,medial and lateral malleolus of femur,and trochlea of femur,were evaluated on MRI.A total of 456 articular cartilages were detected by arthroscopy in 54 cases,96 cases,147 cases,82 cases,and 77 cases of grade 0,grade Ⅰ,grade Ⅱ,grade Ⅲ,grade Ⅳ.MRI MEGRE sequence detected 54,96,150,82 and 74 cases of grade 0,grade Ⅰ,grade Ⅱ,grade Ⅲ and grade Ⅳ,respectively.Conventional sequences were detected in 55 cases,93 cases,147 cases,83 cases and 78 cases of grade 0,grade Ⅰ,grade Ⅱ,grade Ⅲ and grade Ⅳ respectively.The sensitivity of MRI MEGRE sequence in the classification diagnosis of knee cartilage injury was significantly higher than that of conventional sequence(P<0.05).Conclusion:In the early diagnosis of knee cartilage injury,MRI MEGRE sequence has higher quality imaging images than conventional sequence,and has higher diagnostic efficacy in the classification of knee cartilage injury.
