MSCT联合磁共振对老年膝关节隐匿性骨折的诊断效能分析

Analysis of Diagnostic Efficacy of MSCT Combined with MRI in the Diagnosis of Occult Fractures of the Knee in Elderly Patients

目的探讨多层螺旋CT(MSCT)联合磁共振诊断老年人膝关节隐匿性骨折效能。方法选取2021年3月至2024年1月收治的疑似老年人膝关节隐匿性骨折患者120例作为研究对象,入院后均行MSCT及磁共振检查,比较MSCT、磁共振单独及联合检查对老年人膝关节隐匿性骨折诊断价值。结果38例复查MSCT,伤后第2周检出6例,第3周检出17例,第4周检出13例,>4周检出2例;联合检查诊断老年人膝关节隐匿性骨折的敏感度100.00%(109/109)、准确度100.00%(120/120)高于MSCT 84.17%(101/120)、91.67%(110/120)和磁共振85.83%(103/120)、94.17%(113/120),漏诊率0(0/109)低于MSCT的7.34%(8/109)、磁共振5.50%(6/109)(P<0.05)。结论MSCT、磁共振联合诊断可有效提高老年人膝关节隐匿性骨折诊断准确率,为临床早期诊断提供参考。

Objective To explore the efficacy of multi-slice spiral CT(MSCT)combined with magnetic resonance im-aging(MRI)in the diagnosis of occult fracture of the knee joint in the elderly.Methods A total of 120 elderly patients with suspected occult fracture of the knee admitted from March 2021 to January 2024 were selected as the research subjects.MSCT and MRI were performed after admission.The diagnostic value of MSCT and MRI alone and in combination in elderly patients with occult fracture of the knee was compared.Results In 38 patients undergoing MSCT again,6 patients were detected at the 2nd week after injury,17 patients at the 3rd week,13 patients at the 4th week,and 2 patients after the 4th week.The sen-sitivity[100.00%(109/109)]and accuracy of[100.00%(120/120)]were higher than those of MSCT in the diagnosis of occult fracture of the knee in the elderly[84.17%(101/120),91.67%(110/120)],and MRI[85.83%(103/120),94.17%(113/120)];the missed diagnosis rate[0(0/109)]was lower than that of MSCT[(7.34%)(8/109)]and MRI[(5.50%)(6/109)](P<0.05).Conclusion The combined diagnosis of MSCT and MRI can effectively improve the diagnostic accuracy of occult fracture of the knee joint in the elderly,and provide reference for early clinical diagnosis.
