外伤性膝关节隐性骨折伴韧带损伤行CT与MRI检查的影像特征及诊断效果对比研究OA
Comparative Study of CT and MRI Imaging Features and Diagnostic Results of Traumatic Recessive Fracture of Knee Joint with Ligament Injury
目的:探讨与对比外伤性膝关节隐性骨折伴韧带损伤行CT与核磁共振成像(MRI)检查的影像特征及诊断效果.方法:选取 2022年 6月—2023年 5月我院收治的 700例疑似为外伤性膝关节隐性骨折患者为研究对象,所有患者都给予CT与MRI检查,记录影像学特征并判断诊断效果.结果:在 700例患者中,手术确诊为外伤性膝关节隐性骨折伴韧带损伤 156例(韧带损伤组),占比 22.29%.韧带损伤组的CT征象双边征、骨质破坏、充气征、软组织影等占比分别为78.85%、82.69%、83.97%、82.05%,均高于非韧带损伤组的 20.40%、22.79%、28.31%、19.12%,组间差异有统计学意义(P<0.05).韧带损伤组的T 1WI、T 2WI序列低信号占比分别为 78.85%、83.97%,均高于非韧带损伤组的 28.31%、29.04%,组间差异有统计学意义(P<0.05).在 700例患者中,CT与MRI分别诊断为外伤性膝关节隐性骨折伴韧带损伤 151例与155例,外伤性膝关节隐性骨折伴韧带损伤行CT与MRI诊断的敏感性为 96.15%(150/156)、99.36%(150/156),特异性为99.82%(543/544)、100.00%(544/544),不同检查方法的诊断敏感性与特异性对比,组间差异无统计学意义(P>0.05).结论:外伤性膝关节隐性骨折患者多伴随有韧带损伤,在CT检查中多表现为双边征、充气征等,在MRI多序列上多表现为低信号,CT与MRI检查外伤性膝关节隐性骨折伴韧带损伤都有很好的诊断敏感性与特异性.
Objective:To investigate and compare the imaging features and diagnostic effect of CT and magnetic resonance imaging(MRI)in the diagnosis of traumatic occult fracture of knee joint with ligament injury.Methods:700 patients with suspected traumatic occult knee fractures admitted to our hospital from June 2022 to May 2023 were selected as the research objects.All patients were given CT and MRI examinations,and the imaging features were recorded and the diagnostic effect was judged.Results:Among the 700 patients,156 cases were diagnosed as traumatic knee occult fracture with ligament injury(ligament injury group),accounting for 22.29%.The proportions of bilateral sign,bone destruction,inflation sign and soft tissue shadow in the ligament injury group were 78.85%,82.69%,83.97%and 82.05%,respectively,which were higher than 20.40%,22.79%,28.31%and 19.12%in the non-ligament injury group,and the differences between the groups were statistically significant(P<0.05).The proportion of hypointensity on T1WI and T2WI in the ligament injury group was 78.85%and 83.97%,respectively,which was higher than 28.31%and 29.04%in the non-ligament injury group,and the difference between the groups was statistically significant(P<0.05).Among the 700 patients,151 cases and 155 cases of traumatic knee occult fracture with ligament injury were diagnosed by CT and MRI,respectively.The sensitivity of CT and MRI in the diagnosis of traumatic knee occult fracture with ligament injury was 96.15%(150/156)and 99.36%(150/156),respectively.The specificity was 99.82%(543/544)and 100.00%(544/544).There was no significant difference in the diagnostic sensitivity and specificity between the two groups(P>0.05).Conclusion:Patients with traumatic occult fracture of knee joint are often accompanied by ligament injury,which are mostly manifested as bilateral sign and inflation sign on CT examination,and are mostly manifested as low signal on MRI multi-sequence.CT and MRI have good diagnostic sensitivity and specificity for traumatic occult fracture of knee joint with ligament injury.
