高分辨率CT用于肺部小结节良恶性鉴别诊断的效果分析OA

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.
