Clinical Study on Qualitative Analysis of Highly Concentrated Pulmonary Nodules Using PET/CT Combined with Artificial Intelligence and 512 Slice Spiral CT
Objective:To explore the qualitative analysis value of positron emission tomography(PET)/computed tomography(CT)combined with artificial intelligence and 512 slice spiral CT for high coagulation nodules in the lungs.Methods:A retrospective analysis was conducted on the examination data of 220 patients with pulmonary nodules.All subjects underwent PET/CT and spiral CT examinations,and artificial intelligence analysis was used for PET/CT imaging.Using pathological results as the gold standard,compare the diagnostic value of different methods for diseases,compare the viewing time and image quality,and calculate the diagnostic efficacy of different methods.Results:Pathology confirmed 175 cases of benign nodules and 45 cases of malignant nodules.The consistency between PET/CT combined with artificial intelligence analysis and pathological results was 0.7564,which was higher than the consistency between spiral CT and pathological results of 0.512(P<0.05).The detection rate of inflammatory pseudotumors using PET/CT combined with artificial intelligence analysis was 99.02%,which was higher than the detection rate of 93.14%using spiral CT(P<0.05).The diagnostic sensitivity of PET/CT combined with artificial intelligence analysis was 95.56%,which was higher than the 77.78%of spiral CT examination(P<0.05).Conclusion:The combination of PET/CT and artificial intelligence analysis has high value in qualitative analysis of high concentration nodules in the lungs,which can shorten the time of film reading and improve the sensitivity of diagnosis.
