Myocarditis Severity Index (MRI-based): Explanation and Clinical Context The Myocarditis Severity Index (MSI) is a composite score derived from key cardiac MRI parameters, including Left Ventricular Ejection Fraction (LVEF), T2 Mapping, and Late Gadolinium Enhancement (LGE). This index aids in assessing the severity of myocarditis and predicting clinical outcomes. A higher MSI indicates greater myocardial inflammation and potential for adverse cardiac events.
Clinicians utilize this index to guide treatment decisions and monitor disease progression.
