摘　　要：目的:分析肺结节患者应用CT与磁共振成像的效果。方法:选取2019年12月—2022年6月河南大学第一附属医院收治的68例肺结节患者作为研究对象,根据不同检查方式分为CT组及磁共振成像组。所有患者均进行CT、磁共振成像检查。以最终病理诊断结果作为金标准,比较两种检查方式的特异性、灵敏度、准确度、阳性预测值、阴性预测值。结果:68例肺结节患者经临床病理学检查发现,肺结节阳性患者58例,阴性10例。CT检查发现肺结节阳性56例,阴性12例,肺结节阳性检出率为82.35%;磁共振成像肺结节阳性45例,阴性23例,肺结节阳性检出率为66.18%。CT检查阳性检出率高于磁共振成像,差异有统计学意义(χ^(2)=4.655,P<0.05);CT检查结果中结核球、鳞癌检出率与磁共振成像比较,差异有统计学意义(χ^(2)=4.098、4.225,P<0.05);炎性结节及腺癌检测结果比较,差异无统计学意义(χ^(2)=0.605、0.763,P>0.05)。CT检查诊断效能中的灵敏度为83.87%,准确率为79.41%,特异性为33.33%,阳性预测值为92.90%,阴性预测值为33.33%;磁共振成像的灵敏度为72.73%,准确率为70.59%,特异性为61.54%,阳性预测值为88.90%,阴性预测值为61.50%。结论:CT及磁共振成像检查应用于肺结节患者中,可通过不同基物质浓度等多参数定量的影像学诊断措施准确诊断结节的性质,同时为肺结节良恶性及不同病理类型提供形态学和功能学信息,有助于临床早期快速鉴别肺结节良恶性,减轻患者检查负担,改善其预后效果。Objective:To analyze the results of applying CT versus magnetic resonance imaging in patients with pulmonary nodules.Methods:68 patients with lung nodules admitted to the hospital from December 2019 to June 2022 were selected as research subjects,and were divided into CT group and magnetic resonance imaging group according to different examination modalities.All patients underwent CT and magnetic resonance imaging.The specificity,sensitivity,accuracy,positive predictive value,and negative predictive value of the two examination modalities were compared using the final pathologic diagnosis as the gold standard.Results:Clinicopathologic examination of 68 patients with pulmonary nodules revealed 58 positive patients and 10negative patients.CT examination revealed positive lung nodules in 56 cases and negative in 12 cases,and the positive detection rate of lung nodules was 82.35%.Magnetic resonance imaging was positive for lung nodules in 45 cases and negative in 23 cases,and the positive detection rate of lung nodules was 66.18%.The positive detection rate of CT examination was higher than that of magnetic resonance imaging,and the difference was statistically significant(χ^(2)=4.655,P<0.05).The detection rate of tuberculosis ball and squamous carcinoma in the CT examination results was statistically significant compared with that of magnetic resonance imaging(χ^(2)=4.098,4.225;P<0.05).There was no statistically significant difference in the comparison of inflammatory nodule and adenocarcinoma detection results(χ^(2)=0.605,0.763;P>0.05).The sensitivity of CT examination in diagnostic efficacy was 83.87%,accuracy was 79.41%,specificity was 33.33%,positive predictive value was 92.90% and negative predictive value was 33.33%.Magnetic resonance imaging had a sensitivity of 72.73%,an accuracy of 70.59%,a specificity of 61.54%,a positive predictive value of 88.90%,and a negative predictive value of 61.50%.Conclusion:CT and magnetic resonance imaging(MRI) examinations applied to patients with pulmonary nodules can accur
