It gives an overview of the current evidence of the ability of CMR to detect myocardial inflammation and discusses the added value as well as its limitations in clinical settings. Because of the large variety of symptoms and the limited specificity of other non-invasive procedures, the identification of myocardial inflammation is of paramount importance. Because of its accuracy in imaging ventricular volumes and function and its unique ability to visualize myocardial edema, scar, and other tissue abnormalities, CMR has emerged as the prime non-invasive diagnostic tool in patients with acute myocarditis. The presence of myocardial inflammation is not specific to viral myocarditis or other forms of acute myocardial injury, and the regional distribution within the myocardium helps differentiate acute myocarditis from other diseases. The currently recommended diagnostic criteria (Lake Louise Criteria) include markers for hyperemia\/capillary leak, edema, and inflammatory scarring. Their diagnostic accuracy of close to 80% is satisfactory to rule in myocarditis, yet the negative predictive value is less than 70%. Novel CMR techniques, especially T1 and T2 mapping, have been shown to further improve the diagnostic utility.<\/ns4:p>","DOI":"10.12688\/f1000research.14857.1","type":"journal-article","created":{"date-parts":[[2018,7,30]],"date-time":"2018-07-30T10:06:07Z","timestamp":1532945167000},"page":"1153","update-policy":"https:\/\/doi.org\/10.12688\/f1000research.crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["The unique role of cardiovascular magnetic resonance imaging in acute myocarditis"],"prefix":"10.12688","volume":"7","author":[{"given":"Michael","family":"Chetrit","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1204-5647","authenticated-orcid":false,"given":"Matthias G.","family":"Friedrich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2560","published-online":{"date-parts":[[2018,7,30]]},"reference":[{"key":"ref-1","doi-asserted-by":"publisher","first-page":"779-92","DOI":"10.1016\/j.jacc.2011.09.074","article-title":"Update on myocarditis.","volume":"59","author":"I Kindermann","year":"2012","journal-title":"J Am Coll Cardiol."},{"key":"ref-2","doi-asserted-by":"publisher","first-page":"415-22","DOI":"10.1086\/427282","article-title":"Cardiac findings during uncomplicated acute influenza in ambulatory adults.","volume":"40","author":"M Ison","year":"2005","journal-title":"Clin Infect Dis."},{"key":"ref-3","doi-asserted-by":"publisher","first-page":"1823-5","DOI":"10.1016\/j.jacc.2005.03.002","article-title":"Cardiovascular magnetic resonance for the diagnosis of acute myocarditis: prospects for detecting myocardial inflammation.","volume":"45","author":"P Liu","year":"2005","journal-title":"J Am Coll Cardiol."},{"key":"ref-4","doi-asserted-by":"publisher","first-page":"1914-31","DOI":"10.1016\/j.jacc.2007.09.008","article-title":"The role of endomyocardial biopsy in the management of cardiovascular disease: a scientific statement from the American Heart Association, the American College of Cardiology, and the European Society of Cardiology.
