Cardiac Magnetic Resonance Imaging
Recently, cardiac magnetic resonance imaging (cMRI or CMR) has been shown to be very useful in diagnosing myocarditis by visualizing markers for inflammation of the myocardium.[1]. In a recent study involving 79 patients suspected of having ACS, 81% of the patients (including those with preserved ejection fraction) were diagnosed with myocarditis based on CMR findings[2].
Gadolinium-enhanced magnetic resonance imaging (MRI) aid in assessing the extent of myocardial edema and inflammation. Extent of myocardial scarring has also been assessed with delayed enhanced MRI[3].
CMR was reported to have a sensitivity of 76%, specificity of 95.5%, and overall diagnostic accuracy of 85% when any-two of the following three sequences were used[4].
- Focal and global T2 signal intensity
- Myocardial global relative enhancement
- Delayed gadolinium enhancement
