Quantitative 13N-Ammonia Cardiac Rest/Stress Digital PET/CT

Trial ID or NCT#



not recruiting iconNOT RECRUITING


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.
