Indications and Purpose of the Scan
- Myocarditis is an inflammatory disease that may be caused by a variety of etiologies. Myocarditis can be a challenging diagnosis. CMR has become a primary technique for assessment of myocardial inflammation.
Why CMR (specific advantages for this topic)
- CMR is important because it can help confirm the diagnosis, assess the presence of inflammation as well as pericardial involvement and provide prognostic data.

- This study demonstrated that tissue characterization with CMR is an effective method of risk stratifying patients with suspected myocarditis.

- This study demonstrated that in acute myocarditis and preserved left ventricular ejection fraction, mid-myocardial late gadolinium enhancement is associated with worse prognosis.
