静息状态下CT冠状动脉造影结合CT首过心肌灌注成像诊断阻塞性冠脉病变
Diagnosis of obstructive coronary artery disease using CT coronary angiography combined with CT first-pass myocardial perfusion imaging at rest
摘要
Abstract
Objective To assess the feasibility and accuracy of CT coronary angiography (CTCA) combined with CT first-pass myocardial perfusion imaging (CT first-pass MPI) at rest for diagnosis of obstructive coronary artery disease (CAD).Methods Fifty-five patients,suspected or diagnosed as CAD,were performed with CTCA and CAG within 2 weeks.CT first-pass MPI detected myocardial ischemia through analyzing the raw date of CTCA.Results Comparison with the results of CAG,the sensibility,specificity,positive predictive value (PPV),negative predictive value (NPV) and accuracy of CT first-pass MPI at rest for detecting obstructive CAD were 84.6％,68.8％,86.8％,64.7％ and 80.0％,respectively; and 92.3％,93.8％,97.3％,83.3％,92.7％ for CTCA combined with CT first-pass MPI,respectively.Conclusions CTCA combined with CT first-pass MPI at rest could detect obstructive CAD feasibly and accurately.关键词
