目的:探讨膝关节半月板损伤的影像学变化及磁共振成像(MRI)的诊断价值。方法:选择贵州航天医院收治的44例膝关节半月板损伤的患者作为研究对象,随机分成2组,各22例。对照组行计算机断层扫描(CT)检查,观察组MRI检查,以关节镜检查结果为金标准,将两组检查结果进行分析对比。结果:关节镜检查与MRI检查对膝关节损伤程度检出率相比差异无统计学意义(P>0.05);关节镜检查与CT检查对膝关节损伤程度检出率相比差异有统计学意义(P<0.05);MRI检查与CT检查对膝关节损伤程度检出率相比差异有统计学意义(P<0.05)。结论:与常规影像学相比,膝关节半月板损伤采用MRI检查更加准确,MRI可根据形态及信号准确的判断半月板受损程度,为临床治疗提供切实依据。
Objective: To investigate the imaging changes of knee meniscus injury and the diagnostic value of magnetic resonance imaging (MRI). Methods: Forty-four patients with knee joint meniscus injury admitted to Guizhou Aerospace Hospital were randomly divided into two groups (n = 22 in each group). The control group underwent computed tomography (CT) examination and MRI examination in the observation group. The results of arthroscopy were the gold standard, and the results of the two groups were analyzed and compared. Results: There was no significant difference in the detection rate of knee joint between arthroscopy and MRI (P> 0.05). There was significant difference between arthroscopy and CT in the detection rate of knee joint injury (P <0.05). There was significant difference between MRI and CT in the detection rate of knee joint injury (P <0.05). Conclusion: Compared with conventional imaging, MRI of knee meniscus injury is more accurate. MRI can accurately determine the degree of meniscus injury according to the morphology and signal, and provide a solid foundation for clinical treatment.
