研究概览
简要总结
This prospective imaging study investigates the diagnostic ability of Gallium-68 DOTA-TOC (68Ga-DOTA-TOC) positron emission tomography/computed tomography (PET/CT) in the clinical work-up of patients with 1) clinically suspected acute myocarditis (n=30-40) and 2) clinically suspected cardiac sarcoidosis (n=30-40) using clinical diagnostic criteria as well as endomyocardial biopsy as reference. Furthermore, 68Ga-DOTA-TOC PET/CT findings will be compared with results from contrast-enhanced magnetic resonance imaging (MRI) and in case of cardiac sarcoidosis even Fluorine-18 fluorodeoxyglucose (18F-FDG) PET/CT, which are both performed as part of the clinical routine work-up.

研究组 & 干预措施
Acute myocarditis
Included patients with clinically suspected acute myocarditis (n=30-40) will undergo a 68Ga-DOTA-TOC PET/CT and a blood sample will be taken. Furthermore, participants will undergo a contrast-enhanced MRI and endomyocardial biopsy (if clinically indicated) as part of the clinical routine work-up.
干预措施: 68Ga-DOTA-TOC PET/CT (Diagnostic Test)

Cardiac sarcoidosis
Included patients with clinically suspected cardiac sarcoidosis (n=30-40) will undergo a 68Ga-DOTA-TOC PET/CT and a blood sample will be taken. Furthermore, participants will undergo a contrast-enhanced MRI, 18F-FDG PET/CT and endomyocardial biopsy as part of the clinical routine work-up.
