Summary

The overall goal of this project is to compare the absolute quantification of myocardial perfusion done by using CT myocardial perfusion imaging (CT-MPI) and the coronary flow measured by using CT Fractional Flow Reserve analysis (CT-FFR) to the gold standard represented by PET myocardial perfusion imaging (PET-MPI).

Description

Participants will be patients who are scheduled to undergo PET Myocardial Perfusion Imaging, which is the traditional method for evaluating patients with suspected blockages or narrowing of the heart vessels (coronary artery disease) causing impaired blood to flow to the heart muscle (myocardium).

The purpose of the study is to determine and compare the newest heart imaging equipment which allows the non-invasive evaluation of coronary anatomy, coronary flow and myocardial perfusion in patients with suspected or proven coronary artery disease (CAD) with the actual gold-standard for quantitative myocardial perfusion assessment. In order to achieve this aim, the study team will compare heart scan results from a computed tomography (CT) Myocardial Perfusion Imaging (CT-MPI) scan and CT-Fractional Flow Reserve (FFR) with the actual standard clinical care represented by a PET Myocardial Perfusion Imaging (PET-MPI) study.
