磁共振成像、多层螺旋CT检查对成人外伤性膝关节损伤的诊断价值分析

Diagnostic Value of Magnetic Resonance Imaging and Multi-slice Spiral CT in the Diagnosis of Traumatic Knee Injury in Adults

目的探讨MRI以及MSCT检查对成人外伤性膝关节损伤的诊断价值,并分析其临床价值。方法收集我院2017年11月至2019年6月收治的67例膝关节损伤患者的临床资料,分析67例患者MSCT检查和MRI检查图像表现,对比两种检查对外伤性膝关节损伤的诊断情况。结果MSCT对韧带损伤、半月板损伤、骨质损伤、关节腔积液的诊断正确率分别为83.33%、78.57%、86.67%、90.91%,MRI检查分别为100%、96.42%、93.33%、90.91%,MRI对半月板损伤诊断正确率高于MSCT(P<0.05);M S CT对外伤性膝关节损伤整体诊断正确率为82.08%,低于MRI检查95.52%(P<0.05)。MSCT检查中,韧带损伤患者图像可见韧带肿胀,密度呈不均匀增高,边缘模糊;在MRI中可见条状阴影,伴有边缘模糊增粗等现象,T1WI序列低信号,T2WI序列较高信号,STIR序列高信号。结论MSCT检查可对膝关节病变诊断有一定的参考价值,但是MRI检查更能全面地反映膝关节损伤情况,且诊断正确率高于MSCT,可作为膝关节损伤首选检查。

Objective To explore the diagnostic value of MRI and MSCT examination in diagnosing traumatic knee injury in adults and analyzing its clinical signficance.Methoods The clinical data of 67 patients with knee joint injuries admitted to our hospital from November 2017 to June 2019 were collected.The images of MSCT and MRI were analyzed in 67 patients.The diagnosis for traumatic knee injury was compa red between the two examinations.Results The diagnostic accuracy of MSCT for ligament injury,meniscus injury,sclerotin injury,and joint effusion was 83.33%,78.57%,86.67%,and 90.91%,respectively,and diagnostic accuracy of MRI was 100%,96.42%,93.33%,and 90.91%,respectively.The diagnostic accuracy of MRI for meniscal injury was higher than that of MSCT(P<0.05).The overall diagnostic accuracy of MSCT for traumatic knee injury was 82.08%,which was lower than 95.52%of MRI(P<0.05).In the MSCT exa mination,the images of patients with liga ment inju ry showed swelling of the ligament,uneven increasing of density,and blurred edges.MRI shows shadows like strip,accompanied by blu rring and thickening edges,a low signal of T1 WI sequence,a higher signal of T2 WI sequence,and a high signal of STIR sequence.Conclusion MSCT examination can have a certain reference value for the diagnosis of knee joint disease,but MRI examination can more comprehensively reflect the knee joint injury,and the diagnostic accuracy is higher than that of MSCT,which can be used as the first choice for knee joint inju ry.
