摘要:目的:分析磁共振成像检查对半月板损伤的临床诊断价值。方法:回顾分析我院2018年3月-2021年3月期间收治的60例临床怀疑半月板损伤患者,患者均接受MRI和关节镜检查,并将关节镜检查结果作为此次MRI检查的金标准,分析MRI检查准确率、灵敏度、特异度等。结果:经MRI检查后显示0级24例,Ⅰ级4例,Ⅱ级5例,Ⅲ级27例;关节镜检查显示退变35例,撕裂25例。关节镜检查共58例得到确诊(96.67%),MRI检查共57例得到确诊(95.00%),MRI检查灵敏度为98.28%(57/58)、特异度为50.00%(1/2),阳性预测值为98.28%(57/58),阴性预测值为50.00%(1/2)。关节镜检查准确率为95.00%,MRI检查准确率为96.67%,组间数据差异无统计学意义(P>0.05)。结论:临床诊断半月板损伤时可考虑采用磁共振成像进行检查,其灵敏度、准确性均较高,可为临床诊治半月板损伤提供依据。

Abstract: Objective: To analyze the clinical diagnostic value of MRI in meniscus injury. Methods: 60 patients with suspected meniscus injury in our hospital from March 2018 to March 2021 were retrospectively analyzed. All patients received MRI and arthroscopy, and the results of arthroscopy were taken as the gold standard of MRI examination. The accuracy, sensitivity and specificity of MRI examination were analyzed. Results: after MRI examination, there were 24 cases of grade 0, 4 cases of grade Ⅰ, 5 cases of grade Ⅱ and 27 cases of grade Ⅲ; Arthroscopy showed degeneration in 35 cases and tear in 25 cases. Results: 58 cases were diagnosed by arthroscopy (96.67%) and 57 cases by MRI (95.00%). The sensitivity, specificity, positive predictive value and negative predictive value of MRI were 98.28% (57 / 58), 50.00% (1 / 2), 98.28% (57 / 58) and 50.00% (1 / 2), respectively. The accuracy of arthroscopy was 95.00% and 96.67% respectively, There was no significant difference between the two groups(P > 0.05). Conclusion: MRI can be used in clinical diagnosis of meniscus injury, which has high sensitivity and accuracy, and can provide a certain basis for clinical diagnosis and treatment of meniscus injury.

半月板为人体膝关节的一個重要组成结构,对膝关节稳定有维持作用,确保膝关节运动协调,并有吸收震荡、负重的效果[1]。半月板遭受损伤,可导致膝关节肿胀、疼痛,甚至发生功能性障碍,严重影响人体正常活动。相对于其他组织,半月板供血较少,若遭受损伤,自愈难度非常大,若不及时诊治,会损伤软骨组织,引发关节炎等症状。因此,早期有效诊治非常重要。检查半月板损伤的金标准为关节镜。虽检查准确度较高,但此检查方式创伤性较大,重复操作的难度大,无法用于常规检查[2]。磁共振成像(MRI)为断层成像技术,检查操作具有无创优势,且对软组织分辨率高,已逐步用于诊断半月板损伤[3]。但目……
