摘    要:目的:通过比较临床检查、常规磁共振检查(MRI)、间接磁共振膝关节腔内造影检查(间接MRA)和膝关节镜术中所见,探讨间接MRA用于膝关节半月板撕裂诊断中的价值.材料和方法:本次研究中我们共收集125例曾行膝关节镜手术患者,全部患者都经过详细的病史采集和体格检查,其中57例患者术前行MRI检查,其中21例患者做MRI检查后立即做间接MRA,以膝关节镜为金标准,对各种检查发现进行互相比较.结果:①临床检查:敏感性75.47%、特异性69.44%、准确性72.00%.②MRI检查:敏感性82.86%、特异性54.55%、准确性71.93%.③间接MRA检查:敏感性100%、特异性90.00%、准确性95.23%.结论:间接MRA在诊断膝关节半月板撕裂方面具有很高的敏感性、特异性和准确性.

Abstract:Purposes:Magnetic resonance arthrography of the knee has been used rarely in our country.In order to investigate the value of indirect MRA in the diagnosis of meniscal tears of the knee,we compared the founds of clinical examination,conventional magnetic resonance imaging and indirect magnetic resonance arthrography imaging with the founds of arthroscopy.Materials and Methods:We collected125pa-tients who were diagnosed as meniscal tears and accepted arthroscopies of knee.Among them57patients accepted the conventional MRI.Among the57patients,21cases accepted indirect MRA after MRI.The founds of different kinds of examination were compared each other with the founds of arthroscopies,which were regarded as typical standard.Results:Meniscal Tears were detected by clinical examina-tion/MRI/MRA with sensitivities of75.47%/82.86%/100%,specificities of69.44%/54.5%/90.00%and accuracies of72.00%/71.93%/95.23.Conclusion:Indirect MR arthorgraphy can effectively elevate the accuracy for detecting the meniscal tear of the knee.
Keywords:Meniscus Magnetic resonance imaging Arthrography
