比较CT和MRI成像技术评估髋部隐匿性骨折诊断效能的meta分析

To compare the diagnostic efficacy of CT and MRI in the evaluation of occult hip fracture:A MetaAnalysis

后共排除34篇。最终纳入本研究10篇。MRI诊断价值的AUC(Area Under Curve)面积虽然大于CT诊断价值,未见明显统计学差异(Z=1.33<1.96,P>0.05);MRI诊断髋部隐匿性骨折特异度明显高于CT诊断价值(P<0.05)。结论对于髋部外伤后X线检查阴性,但仍然怀疑为有骨折或疼痛症状明显的患者,推荐MRI成为必查项,可以显著提高隐匿性骨折的检出率和诊断的正确性,为临床诊断和合理选用治疗方案提供准确可靠依据。

Objective To summarize the data of occult hip fracture and analyze better diagnostic methods by comparing CT and MRI imaging techniques.Methods The literature on CT and MRI evaluation of occult hip fractures published in the English literature database from the establishment of the database to 2022 was statistically analyzed by meta-analysis.The heterogeneity of the included studies was analyzed by Review Manager 5.3 software,and the publication bias was tested by Stata 12.0 software.Results 10 articles were finally included in this study.Although the AUC area of MRI was greater than that of CT,there was no significant difference(z=1.33<1.96,P>0.05);The specificity of MRI in the diagnosis of occult hip fracture was significantly higher than that of CT(P<0.05).Conclusions for patients with negative X-ray examination after hip trauma,but still suspected to have obvious fracture or pain symptoms,MRI is recommended as a necessary item,which can significantly improve the detection rate and diagnostic accuracy of occult fracture,and provide accurate and reliable basis for clinical diagnosis and reasonable selection of treatment scheme.
