磁共振成像联合数字X射线摄影检查对隐匿性胫骨平台骨折的诊断价值

The Diagnostic Value of MRI Combined with DR in Occult Tibial Plateau Fracture

目的:探讨磁共振成像(MRI)联合数字X射线摄影(DR)检查对隐匿性胫骨平台骨折(TPOF)的诊断价值;方法:选取2021年11月~2023年12月本院收治的103例疑似TPOF患者为研究对象,以关节镜检查、手术结果作为金标准,诊断结果为阳性(n=74),阴性(n=29),所有患者均先行MRI检查,后行DR检查,分析MRI、DR单独及其联合检查对TPOF的阳性检出率,并对比其诊断效能。结果:MRI、DR联合诊断灵敏度为95.95%、特异度为75.86%、准确率为90.29%及阴性预测值88.00%均高于MRI、DR单独诊断,联合诊断的漏诊率为4.05%,低于单独诊断(P<0.05)。结论:在影像学检查中DR联合MRI检查对TPOF的临床应用价值高,临床上可将两者结合检查,对疑似隐性TPOF诊断提供更可靠的影像学依据。

Objective:To evaluate the diagnostic value of magnetic resonance imaging(MRI)combined with digital radiography(DR)in occult tibial plateau fracture(TPOF).Methods:From November 2021 to December 2023,103 patients with suspected TPOF in our hospital were selected as research objects,and the results of arthroscopy and surgery were taken as the gold standard.The diagnostic results were positive(n=74)and negative(n=29).All patients were examined by MRI first and then by DR.The positive detection rate of TPOF by MRI and DR Alone and their combined examination were analyzed,and the diagnostic efficiency was compared.Results:The sensitivity,specificity,accuracy and negative predictive value of MRI and DR Combined diagnosis were 95.95%,75.86%,90.29%and 88.00%higher than that of MRI and DR Alone diagnosis.The missed diagnosis rate of combined diagnosis was 4.05%,lower than that of single diagnosis(P<0.05).Conclusion:In the imaging examination,DR Combined with MRI examination has high clinical application value for TPOF,which can be combined clinically to provide more reliable imaging basis for the diagnosis of suspected recessive TPOF.
