A cardiac MRI (CMR) is worth a thousand labs. Or, that appears to be the case in myocarditis. Dr. Heidecker et al demonstrated that late gadolinium enhancement (LGE) on CMR is unrelated to cardiac enzymes and inflammatory markers, and more prognostic in myocarditis.

Twenty-four patients were prospectively enrolled (75% male, median age 32, 13% w/ concomitant CAD) at the University of Zurich after being diagnosed with myocarditis. Myocarditis diagnosis was based on clinical features, symptom onset < 10 days, ECG, and elevated high-sensitivity troponin T in the absence of acute obstructive coronary disease.
