Table 1 Diagnostic performance of MRI for the assessment of myocardial inflammation in an unselected cohort of consecutive patients (a), in patients with suspected acute myocarditis (b) and in patients with suspected chronic myocarditis (c). 2/3, 2 out of 3 MRI criteria (ER, gRE, LE) positive.

From: Magnetic resonance imaging assessment of myocardial inflammation in 132 unselected, consecutive patients with clinical suspicion of acute or chronic myocarditis - are we as good as we thought?
