摘要
目的探讨CT联合MRI对X线初步诊断为肺癌患者中的应用价值。方法选我院2010年6月到2013年9月期间经X线初步诊断为肺癌的患者132例,均采用CT联合MRI对肿块进行进一步的扫描,并结合术后病理学结果,对比分析CT、MRI及CT联合MRI对经X线初步诊断为肺癌患者的诊断准确率。结果 CT联合MRI、CT、MRI在肺癌的的诊断准确率分别为89.4%、80.0%、66.7%,敏感度分别为92.3%、80.8%、78.2%,特异度分别为50.0%、59.3%、85.2%。经χ2检验,CT联合MRI诊断的准确率、敏感度及特异度均明显优于CT、MRI诊断,其差异有统计学意义(P<0.05或P<0.001)。结论影像学对肺癌的诊断准确率、灵敏度及特异度均以CT联合MRI为最高,建议对经X线初步诊断为肺癌患者进一步实施CT联合MRI检查。
Objective To study the application value of CT combined with MRI examination in patients with lung cancer diagnosed by X-ray.Methods A total of 132 cases registered by X-ray as lung cancer in our hospital during June 2010 to September 2010 were selected and diagnosed by CT and MRI. The diagnosis results of CT, MRI and CT combined with MRI were analyzed referred to the pathological diagnosis results. Results The accuracy rate of CT combined with MRI, CT, and MRI alone were respectively 89.4%, 80.0% and 66.7%, the sensitivity were respectively 92.3%, 80.8% and 78.2%, the specificity were respectively 50.0%, 59.3 and 89.2%, and all indexes diagnosed by CT combined with MRI were significantly higher than CT or MRI alone (P〈0.05 or P〈0.001).Conclusion The accuracy rate, sensitivity and specificity of CT combined with MRI were highest, and we suggest that it's useful for the suspected lung cancer patients to accepted CT and MRI examination.
