目的探讨MRI与CT在急性膝关节损伤诊断中的临床价值。方法对56例本院2012年2月—2017年3月接受治疗的急性膝关节损伤患者实施CT、MRI诊断,根据诊断方式进行分组,并以关节镜检查为金标准,探讨后交叉韧带撕裂的影像学表现、相关数据、准确率。结果 MRI诊断后交叉韧带撕裂的准确率为94.64%,明显高于CT(P<0.05);完全撕裂患者PCL弯曲度指数、PCL角度、AT角均较后交叉韧带部分撕裂与正常患者小,对比差异有统计学意义(P<0.05);后交叉韧带撕裂在CT与MRI诊断中均有明显的影像学特征。结论 MRI诊断急性膝关节后交叉韧带撕裂损伤的准确率高于CT检查,能够在临床诊断中为医师提供可靠性高的信息。
Objective To investigate the clinical value of MRI and CT in the diagnosis of acute knee joint injury. Methods Fifty-six patients with acute knee injury treated in our hospital from February 2012 to March 2017 were diagnosed by CT and MRI, and were divided into groups according to the diagnostic methods. Arthroscopy was used as the gold standard to investigate the effect of posterior cruciate ligament rupture The imaging findings, related data, accuracy. Results The accuracy of MRI in diagnosis of posterior cruciate ligament rupture was 94.64%, which was significantly higher than that of CT (P <0.05). The PCL, PCL and AT angles of patients with complete tear were significantly higher than those of patients with partial tear of posterior cruciate ligament The difference between the two groups was statistically significant (P <0.05). The posterior cruciate ligament tear had obvious imaging features in CT and MRI diagnosis. Conclusion The diagnostic accuracy of MRI in the diagnosis of posterior cruciate ligament rupture of knee is higher than that of CT. It can provide doctors with reliable information in clinical diagnosis.
