                                Rochester, MN
                            
                            
                                
The Researchers are trying to determine if 68Ga-DOTATATE PET/CT imaging will have a similar accuracy as 18FDG PET/CT in diagnosing cardiac sarcoidosis and if it will be able to do so without the need for complex patient dietary preparation that is required with 18FDG PET/CT.

Aims, purpose, or objectives:
    - Develop a retrospective registry of patients with cardiac sarcoidosis
   - Develop a prospective registry of patients with cardiac sarcoidosis
   - Understand the natural history of cardiac sarcoidosis through evaluation of outcomes of patients in the registry
   - Determine risk factors for sarcoid involvement of the heart
   - Evaluate outcomes of patients both treated and untreated with cardiac sarcoidosis
   - Understand the complications of untreated and treated cardiac sarcoidosis
