摘要
目的 探讨基于人工智能肺动脉辅助诊断软件对疑似肺动脉栓塞患者的辅助诊断应用价值.方法 针对2016年6月-2022年12月本院临床疑诊为肺动脉栓塞且行肺动脉CT血管造影(CT angiography,CTA)检查的199例患者的病例资料进行回顾性分析.由不同年资影像诊断医师基于肺动脉CTA图像进行诊断阅片,并由高年资影像诊断医师进行审核,与肺动脉CT血管造影人工智能辅助诊断软件分析结果进行对比,评估该软件和低、中、高年资医师对肺动脉栓塞的诊断效能.采用Kappa检验分别评价人工智能软件与各年资医师基于肺动脉CTA对肺动脉栓塞病灶评估的一致性.结果 人工智能影像诊断辅助软件与高级职称医生基于肺动脉CTA对肺动脉栓塞病灶的评估一致性高(Kappa值为0.913,P＜0.001),而肺动脉CTA人工智能软件的诊断结果与复核后的高年资影像诊断医生基于肺动脉CTA对肺动脉栓塞病灶的评估一致性高(Kappa值为0.755,P＜0.001).结论 人工智能辅助诊断软件基于肺动脉CTA栓塞的判断与诊断医师之间具有良好的一致性,可节省了大量后处理及诊断时间,在临床影像诊断工作中具备辅助诊断使用及推广使用价值.
Abstract
Objective To explore the application value of artificial intelligence(AI)pulmonary artery assisted diagnosis software for suspected pulmonary embolism patients.Methods The data of 199 patients who were clinically suspected of pulmonary embolism and underwent pulmonary artery CT angiography(CTA)from June 2016 to December 2021 were retrospectively analyzed.Images of pulmonary artery CTA diagnosed by radiologists with different experiences and judged by senior radiologists were compared with the analysis results of AI assisted diagnostic software for pulmonary artery CTA,to evaluate the diagnostic efficacy of this software and low,medium,and senior radiologists for pulmonary embolism.The agreement of pulmonary embolism based on pulmonary artery CTA between the AI software and radiologists with different experiences was evaluated using Kappa test.Results The agreement of the AI software and the evaluation of pulmonary embolism lesions by senior radiologists based on pulmonary artery CTA was high(Kappa=0.913,P＜0.001),while the diagnostic results of pulmonary artery CTA AI software was good after judged by senior radiologists based on pulmonary artery CTA(Kappa=0.755,P＜0.001).Conclusions The AI software based on pulmonary artery CTA diagnosis of pulmonary embolism has good consistency with diagnostic images of radilogists,and can save a lot of reconstruction and diagnostic time.It has the value of daily diagnosis work and worthy of clinical promotion.
