The purpose of this study is to investigate the optimal scan timing of single-phase CTP and diagnostic performance of visual assessment to depict myocardial ischemia, by analyzing whole heart dynamic CTP series data in a cohort study.
Efficacy
Primary outcomes are the determination of the optimal scan timing of single-phase myocardial CTP imaging and the investigation of the diagnostic accuracy (sensitivity, specificity, positive and negative predictive value, accuracy) of the optimized single-phase myocardial CT perfusion imaging for detecting myocardial ischemia.
The peak CT attenuation and difference of time to peak between normal and ischemic segment are compared.
