Clinical Study on Qualitative Analysis of Highly Concentrated Pulmonary Nodules Using PET/CT Combined with Artificial Intelligence and 512 Slice Spiral CT

目的:探讨正电子发射断层扫描(PET)/计算机断层扫描(CT)结合人工智能与512层螺旋CT对肺内高凝聚结节定性分析价值。方法:回顾性分析220例肺内结节患者的检查资料,对研究对象均接受PET/CT检查与螺旋CT检查,针对PET/CT检查影像采用人工智能分析。以病理结果为金标准,对比不同方法诊断疾病的价值,比较阅片时间与图像质量,计算不同方法的诊断效能。结果:病理证实175例良性结节,45例恶性结节。PET/CT结合人工智能分析与病理结果一致性为0.7564,高于螺旋CT与病理结果一致性0.512(P<0.05)。PET/CT结合人工智能分析对炎性假瘤检出率99.02%高于螺旋CT检出率93.14%(P<0.05)。PET/CT结合人工智能分析诊断灵敏度为95.56%,高于螺旋CT检查的77.78%(P<0.05)。结论:采取PET/CT结合人工智能分析对肺内高浓聚结节定性分析价值高,可缩短阅片时间,提高诊断的灵敏度。

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.
