Analysis on the Application Value of Energy Spectrum CT Single Energy Imaging Technology in the Diagnosis of Occupational Pneumoconiosis
摘要
Abstract
Objective To analyze the application value of energy spectrum CT single energy imaging technology in the diagnosis of occupational pneumoconiosis.Methods 180 patients with suspected pneumoconiosis admitted to our hospital from April 2022 to April 2024 were selected as the research objects.All patients were given routine CT and energy spectrum CT examination.The imaging characteristics of the two examination methods were recorded and the diagnostic value was judged.Results 140 cases of occupational pneumoconiosis and 40 cases of non-pneumoconiosis in 180 patients with suspected pneumoconiosis were diagnosed according to the diagnostic criteria of pneumoconiosis.The detection rate of characteristic signs of pneumoconiosis patients by energy spectrum CT monochromatic images was higher than that by conventional CT(P＜0.05),and the detection rate of pulmonary nodules and fibrosis changes by 40 keV monochromatic images was higher than that by 140 keV monochromatic images(P＜0.05).Energy spectrum CT monoenergetic images were superior to conventional CT in displaying the fine structure of the lung(P＜0.05),and 40 keV monoenergetic images were superior to 140 keV monoenergetic images in displaying the fine structure of the alveoli and bronchi(P＜0.05).The density(Plain CT value)of pneumoconiosis lesions with energy of 40 keV,80 keV and 140 keV in pneumoconiosis group was higher than that in non-pneumoconiosis group(P＜0.05).The diagnostic accuracy of energy spectrum CT 40 keV monochromatic images for pneumoconiosis was 95.00％(133/140),higher than 87.14％(122/140)of conventional CT,with statistically significant difference(x2=5.315,P=0.021).Conclusions Energy spectrum CT single energy imaging technology has high clinical application value in the diagnosis of occupational pneumoconiosis.By improving the imaging quality,the detection rate of characteristic signs and the display ability of lung fine structure,energy spectrum CT single energy imaging technology can help doctors more accurately judge the condition of patients with occupational pneumoconiosis and formulate the more reasonable treatment plan.关键词
