摘要
目的 分析高分辨率CT对肺部小结节良恶性的鉴别诊断效果.方法 选取2021年2月至2023年4月我院收治的肺部小结节患者96例,均予以常规CT及高分辨率CT检查,评估图像质量,以最终手术病理结果为依据,分别进行两种检查方法与手术病理结果的一致性分析,比较两种检查方式的诊断效能.结果 高分辨率CT图像质量优良率显著高于常规CT(P＜0.05).96例患者经手术病理检查确诊为肺癌阳性70例,阴性26例;高分辨率CT与手术病理诊断结果的一致性较好(κ=0.906,P＜0.001);常规CT与手术病理诊断结果的一致性一般(κ=0.729,P＜0.001).高分辨率CT的灵敏度、特异度、准确率分别为97.14％、92.31％、95.83％,显著高于常规CT的80.00％、50.00％、71.88％(P＜0.05).结论 与常规CT相比,高分辨率CT在肺部小结节良恶性鉴别诊断中的图像质量更佳,诊断效能更好,值得临床应用.
Abstract
Objective To analyze the effect of high-resolution CT in the differential diagnosis of benign and malignant small pulmonary nodules.Methods 96 patients with small pulmonary nodules admitted to our hospital from February 2021 to April 2023 were selected and given routine CT and high-resolution CT.The image quality was evaluated.Based on the final surgical pathology results,the consistency between the two examination methods and surgical pathology results was analyzed,and the diagnostic efficiency of the two examination methods was compared.Results The image quality rate of high-resolution CT was significantly higher than that of routine CT(P＜0.05).Among 96 patients,70 positive cases and 26 negative cases were diagnosed as lung cancer through surgical pathology.The consistency between high-resolution CT and surgical pathology was better(κ=0.906,P＜0.001);The consistency between routine CT and surgical pathology was average(κ=0.729,P＜0.001).The sensitivity,specificity,accuracy of high-resolution CT was 97.14％,92.31％,95.83％,respectively,significantly higher than 80.00％,50.00％,and 71.88％of routine CT(P＜0.05).Conclusions Compared with routine CT,high-resolution CT has better image quality in the differential diagnosis of benign and malignant small pulmonary nodules,with better diagnostic efficiency,which is worthy of clinical application.
