About

The purpose of this study is the assess the diagnostic performance of magnetic resonance imaging in patients with suspected myocarditis by applying different imaging sequences at different MR scanners

Full description

In patients with clinical suspicion of myocarditis biventricular endomyocardial biopsy is performed for definite diagnosis. In addition, patients undergo magnetic resonance imaging at 1.5 Tesla and 3.0 Tesla within 24 hours. The imaging protocol of both scan include assessment of myocardial edema respectively edema ratio; myocardial hyperemia respectively global relative enhancement (gRE); myocardial fibrosis/necrosis respectively myocardial LE and T1 and T2 mapping sentences. Diagnostic performance of different imaging protocols as compared to the findings of endomyocardial biopsies is calculated.

The protocol also includes a follow-up MR can at 3 months.
