【摘要】 目的:探讨MRI和双源CT对隐匿性踝关节骨折的评估价值。方法:选取某院2018年6月～2020年6月疑似隐匿性踝关节骨折的患者120例,术前行MRI、双源CT检查,以手术结果为金标准,比较MRI、双源CT诊断隐匿性踝关节骨折的灵敏度、特异度及准确度。结果:所选120例疑似踝关节隐匿性骨折患者的手术结果显示阳性73例(60.83%);与手术结果比较,双源CT诊断的灵敏度为95.89%(70/73)、特异度为87.23%(41/47)、准确度为92.50%(111/120);MRI诊断的灵敏度为97.26%(71/73)、特异度为93.62%(44/47)、准确度为95.83%(115/120);MRI诊断踝关节隐匿性骨折的灵敏度、特异度、准确度优于双源CT,但差异无统计学差异(P>0.05)。结论:针对隐匿性踝关节骨折患者,MRI、双源CT均具有较高诊断价值,但MRI检查相对更优。更多还原

【Abstract】 Objective: To investigate the value of MRI and dual source CT in the evaluation of occult ankle fractures. Methods: 120 patients with suspected occult ankle fracture in a hospital from June 2018 to June 2020 were selected and examined by MRI and dual source CT before operation. The sensitivity, specificity and accuracy of MRI and dual source CT in the diagnosis of occult ankle fracture were compared with surgical results as the gold standard. Results: Among the 120 patients with suspected occult fracture of ankle joint, 73 cases(60.83%) had positive results. Compared with surgical results, the sensitivity, specificity and accuracy of dual source CT diagnosis were 95.89%(70/73), 87.23%(41/47) and 92.50%(111/120). The sensitivity of MRI diagnosis was 97.26%(71/73), the specificity was 93.62%(44/47), and the accuracy was 95.83%(115/120). The sensitivity, specificity and accuracy of MRI in the diagnosis of occult ankle fractures were better than those of dual source CT, but the difference was not statistically significant(P>0.05). Conclusion: For patients with occult ankle fracture, MRI and dual source CT have high diagnostic value, but MRI examination is relatively better.更多还原
