PET MRI Study in Patients with Cardiac Sarcoidosis
“PET MRI Study in Patients With Cardiac Sarcoidosis”
Myocarditis or inflammatory cardiomyopathy refers to inflammation of the heart muscle (the myocardium). Sarcoidosis is a multisystem granulomatous disorder that may involve the heart, causing inflammation, and potentially resulting in complications including arrhythmia and sudden death. The objective of this study is to evaluate the diagnostic and prognostic significance of simultaneous combined 18F-FDG PET and cardiac MRI imaging in the evaluation of inflammatory cardiomyopathies including cardiac sarcoidosis. Combined PET/MRI imaging may allow for detection and quantification of active myocardial inflammation as well as chronic fibrosis and scarring. Results of this study may allow for earlier detection of cardiac inflammation when compared with methods in current clinical use, and may lead to better understanding of the disease processes contributing to adverse outcomes. Elucidation of imaging findings associated with future adverse event risk may impact patient management such as providing an indication for pacemaker or defibrillator implantation, or escalation of medical therapy.
Diagnostic Test - simultaneous combined 18F-FDG PET and cardiac MRI imaging
Patients will undergo a research study performed with an integrated whole-body PET/MRI imaging system designed for simultaneous PET and MRI acquisition, immediately after standard of care PET/CT exam.
