Quantitative 13N-Ammonia Cardiac Rest/Stress Digital PET/CT
Not Recruiting
Trial ID: NCT03170817
Purpose
Accurate measurements from a non-invasive test like myocardial perfusion positron emission tomography/ computed tomography (PET/CT) may decrease the need for invasive procedures such as cardiac catheterization.The investigators wish to see if the measurements from cardiac catheterization can be predicted using a non-invasive 13N-NH3 digital PET/CT scan.
Official Title
Quantitative Rest/Stress Cardiac Perfusion Digital PET/CT: Comparison Between Noninvasive Imaging and Invasive Coronary Angiography.
