CT血流储备分数与定量血流分数对冠状动脉狭窄的评估价值研究
Study on the Evaluation Value of CT-Fractional Flow Reserve and Quantitative Flow Ratio in the Assessment of Coronary Artery Stenosis
摘要
Abstract
Objective To explore the diagnostic value of the CT-fractional flow reserve(CT-FFR)modules of multiple artificial intelligence software for coronary artery stenosis,and to investigate the accuracy of CT-FFR,quantitative flow ratio(QFR),and their combined value in diagnosing coronary artery stenosis.Methods A retrospective analysis was conducted on 223 patients who underwent coronary angiography(CAG)and coronary CT angiography at Baotou Central Hospital from July 2023 to July 2024.With CAG results as the"gold standard",the diagnostic efficacy of the CT-FFR modules of three software(Shukun,United Imaging,and Bodong)for coronary artery stenosis was compared.The software with the highest diagnostic efficacy was selected to evaluate the accuracy of CT-FFR,QFR,and their combination in diagnosing coronary artery stenosis.Results In terms of diagnosing coronary artery stenosis,the diagnostic accuracy of Shukun was higher than that of United Imaging and Bodong,with a statistically significant difference(P<0.05).The combined diagnostic accuracy of Shukun's CT-FFR module and QFR was higher than that of CT-FFR or QFR alone.Conclusion Among the three software,Shukun has higher diagnostic accuracy in diagnosing coronary artery stenosis,and all three software show good consistency with CAG.The combination of QFR and CT-FFR can improve the accuracy of diagnosing coronary artery stenosis.关键词
