膝关节半月板损伤MRI与关节镜检查对比分析(1)
摘 要 目的:比较核磁共振成像技术(MRI)与关节镜诊断膝关节半月板损伤的效果。方法:收集2017年2月至2018年10月本院收治的40例膝关节半月板损伤患者临床资料,所有患者均接受关节镜检查与MRI检查,比较MRI与关节镜对膝关节半月板损伤分级以及位置的诊断结果。结果:以关节镜检查为金标准,MRI诊断膝关节半月板损伤的总符合率为97.73%,诊断膝关节半月板撕裂的灵敏度为94.44%,特异度为96.21%,Kappa值为0.841;兩种检查方式诊断膝关节半月板撕裂位置的结果差异无统计学意义(P>0.05)。结论:MRI诊断膝关节半月板损伤效果接近于关节镜检查,能够为临床治疗提供可靠依据。

ABSTRACT Objective: To compare the effect of MRI and arthroscopy in the diagnosis of knee meniscus injury. Methods: The clinical data of 40 patients with knee meniscus injury from February 2017 to October 2018 were collected. All patients underwent arthroscopic examination and MRI examination. The results of MRI and arthroscopy in the classification and location of knee meniscus injury were compared. Results: Using arthroscopy as the standard of reference, the total coincidence rate of MRI in the diagnosis of knee meniscus injury was 97.73%. The sensitivity, specificity and Kappa value for diagnosis of knee meniscus tear were 94.44%, 96.21% and 0.841 respectively. There was no significant difference between the two methods in diagnosis of knee meniscus tear(P>0.05). Conclusion: MRI represents a highly accurate method for identifying injury of the meniscus, which can provide reliable basis for clinical treatment.

膝关节是人体重要的功能性关节,发生损伤几率较高,及早发现膝关节损伤并明确损伤具体情况能够为临床治疗的开展提供重要依据[1]。关节镜是临床诊断膝关节半月板损伤的金标准,但因属于有创操作且检查耗时较长,临床开展局限性较高,不宜作为诊断膝关节半月板损伤的常用手段[2]。核磁共振成像技术(MRI)在多种骨科疾病诊断中均有良好效果,具有分辨率高、多方位检查、可重复性好、无创伤或辐射等优点[3]。本院使用MRI诊断膝关节半月板损伤积累了较多经验,现将其与关节镜检查进行比较,以期为MRI的临床应用提供指导。
1 资料与方法
1.1 一般资料
收集2017年2月至2018年10月江西省萍乡市中医院收治的膝关节半月板损伤患者40例,均符合《现代骨科疾病诊断与治疗》[4]中膝关节半月板损伤诊断标准。所有患者均经关节镜检查确诊且无下肢手术史。其中男性15例,女性25例,年龄为25~77岁,平均年龄(50.64±6.53)岁,其中单侧膝关节半月板损伤36例,双侧膝关节半月板损伤4例,共44个膝关节,21例患者有外伤史。所有患者均签署知情同意书。排除多发伤患者;合并其他器质性疾病者;骨质疏松明显者;依从性很差者。
1.2 方法
MRI检查:使用上海联影1.5T MRI成像系统和配套膝关节线圈进行检查,患者在仰卧位下自然伸直患侧下肢,依次行膝关节矢状面、冠状面、横断面扫描,矩阵256×256、层厚2.0 mm、层距0.5 mm、视野200 mm、激励2次。扫描序列:FSE T1WI(重复时间500 ms、恢复时间11 ms)、FSE-FS PDWI(重复时间2 500~3 000 ms、恢复时间23~25 ms)、FSE T2WI(重复时间2 000 ms、恢复时间74 ms)。MRI对膝关节半月板损伤诊断信号分级标准[5]:0级:正常,呈均匀低信号;Ⅰ级:灶性椭圆或球形高信号,未触及半月板关节面;Ⅱ级:水平或线性高信号影,延伸至半月板关节囊边缘但未至半月板关节面边缘;Ⅲ级:半月板内不规则高信号影达1~2个关节面。0级为正常半月板,Ⅰ~Ⅱ级为半月板损伤,Ⅲ级为半月板撕裂。, http://www.100md.com(李建清 梁英 罗子英 贺萍兰 叶峰)
