MRI与CT在肺癌肋骨转移检测中的价值对比

Comparison of MRI and CT in Detection of Rib Metastasis in Lung Cancer

目的探究MRI和CT两种检验方案对肺癌肋骨转移的检测价值。方法回顾性分析2013年1月~2015年12月三门峡市中心医院收治的54例肺癌患者,均经病理检验证实,分别采用MRI、CT两种影像学方法对54例患者进行检验,以病理检验结果为准,对比两种方案的准确性、敏感性及特异性。结果经病理诊断证实本组30例患者确诊为多发性肋骨转移,占总体的55.6%,共135个病灶;在病例数检验结果上,MRI准确性、敏感性及特异性均为100.0%,CT准确性、敏感性及特异性分别为85.2%、90.0%、79.2%,MRI检验均显著高于CT检验,两组对比均具有统计学意义(P<0.05);在病灶数检验结果上,MRI准确性、敏感性及特异性分别为98.5%、100.0%、86.7%,CT准确性、敏感性及特异性分别为53.3%、54.2%、46.7%,MRI检验均显著高于CT检验,两组对比均具有统计学意义(P<0.05)。结论 MRI检验在肺癌患者肋骨转移的检验中,准确性、敏感性及特异性均有较好表现,在病例数和病灶数诊断上均显著优于CT检验,可作为术前诊断的主要检验方案。

Objective To explore the value of MRI and CT in detecting rib metastasis of lung cancer. Methods A retrospective analysis was made of 54 lung cancer patients admitted to Sanmenxia Central Hospital from January 2013 to December 2015. All patients were confirmed by pathological examination, and 54 patients were examined by MRI and CT imaging methods respectively. The accuracy, sensitivity and specificity of the two schemes were compared based on the results of pathological examination. Results The pathological diagnosis confirmed that 30 patients in this group were diagnosed as multiple rib metastases, accounting for 55.6% of the total, with 135 lesions. The accuracy, sensitivity and specificity of MRI were 100.0% and that of CT were 85.2%, 90.0% and 79.2%, respectively. MRI was significantly higher than CT, and the comparison between the two groups was statistically significant（P〈0.05）. The accuracy, sensitivity and specificity of MRI were 98.5%, 100.0% and 86.7% respectively, while the accuracy, sensitivity and specificity of CT were 53.3%, 54.2% and 46.7% respectively. MRI examination was significantly higher than CT examination, and the comparison between the two groups was statistically significant（P〈0.05）. Conclusion MRI examination has higher accuracy, sensitivity and specificity in the examination of rib metastasis in lung cancer patients than CT. MRI examination is significantly superior to CT examination in the diagnosis of the number of cases and lesions, and can be used as the main examination scheme for preoperative diagnosis.
