摘　　要：Objective To investigate the prognostic value of myocardial flow reserve(MFR)measured by SPECT myocardial blood flow(MBF)quantitative technique in patients with intermediate stenoses of coronary arteries.Methods From September 2019 to May 2021,patients with intermediate stenoses(50%to 80%)identified by invasive coronary angiography in Fuwai Hospital,Chinese Academy of Medical Sciences,Fuwai Center China Cardiovascular Hospital,and TEDA International Cardiovascular Hospital were prospectively included.All patients underwentaone-dayrest/stress SPECT myocardial perfusion imaging(MPI)and SPECT MBF quantification.The radioactivity distribution of each segment of the MPI bullseye polar maps were obtained according to the standard 5-point method to obtain the summed stress score(SSS)and the summed difference score(SDS)to determine the existence of abnormality.ROC curve analysis was used to obtain the optimal prognostic cut-off value for MFR.
