摘要
目的探讨研究MSCT与MRI诊断细微及隐匿性骨折中的阳性率和特异性。方法选取我院超声科收治的180例细微及隐匿性骨折患者,分别采用MSCT和MRI对骨折部位进行检测诊断,对比两种检测方法的检出结果、阳性率和特异性。结果 MSCT细微及隐匿性骨折检出率为85.56%,MRI检查结果显示检出率为96.67%,差异具有显著统计学意义(P=0.000);MSCT在检测衰竭骨折、疲劳骨折、隐性创伤骨折方面特异度较MRI稍高,差异不具有统计学意义(P>0.05),在检测隐性股内骨折方面特异度(74.29%)和MRI(94.29%)差异具有统计学意义(P=0.049)。结论采用MSCT和MRI在诊断细微及隐匿性骨折方面均具有一定的应用价值,但是MRI检出率和特异度较高,可以为临床鉴定和治疗提供更可靠的数据。
Objective To investigate the positive rate and specificity of MSCT and MRI in diagnosis of subtle and occult fractures. Methods 180 cases of subtle and occult fracture patients were selected from our hospital, and the diagnosis was made by MRI and MSCT respectively. The results of the two detection methods were compared. Results The detection rate of MSCT and occult fracture was 85.56%, and the detection rate of MRI was 96.67%, the difference was statistically significant(P=0.000).The specificity of MSCT in the detection of failure fracture, fatigue fracture and occult fracture is higher than MRI,but the difference was not statistically significant(P〉0.05),which was statistically significant(P=0.049) in specificity of the detection of the hidden fractures in the stock of MRI(74.29%) and MSCT(94.29%). Conclusion Both MSCT and MRI have certain application value in the diagnosis of subtle and occult fractures, but the detection rate and specificity of MRI can provide more reliable data for clinical evaluation and treatment.
