Brief summary
The purpose of this study is to understand how simultaneous PET/MR acquisition can provide novel qualitative and quantitative biomarkers to guide clinical intervention and predict prognosis of patients with cardiovascular disease.
Detailed description
* To compare regional myocardial uptake of FDG on images obtained on a standard PET camera with the new PET/MR camera, in patients with coronary artery disease. * To compare viability maps obtained with cardiac MR images and FDG-PET for delineation of myocardial infarct core and border zone, in patients with coronary artery disease. * To correlate MRI myocardial strain with relative myocardial FDG uptake in patients with a previous myocardial infarction. * To interrogate if simultaneous acquisition of cardiac PET and viability cardiac MR differ from acquisitions obtained independently, with special focus on attenuation correction methods * To combined MRI scar map with FDG-PET uptake in patients with cardiac sarcoidosis and myocarditis. * To correlate morphologic characteristics of atherosclerotic disease in the thoracic and abdominal aorta with FDG uptake and ferumoxytol enhancement, as a marker of inflammation. * To evaluate cardiac strain and myocardial scar burden in obese patients with and without diabetes.
Interventions
PET-MRI with intravenous Gadolinium and FDG. The entire study will take approximately one hour.
