[The benefit of magnetic resonance for diagnosing cardiomyopathy and myocarditis]. / Prínos magnetické rezonance pro diagnostiku kardiomyopatií a myokarditidy (1. cást).

ABSTRACT

Magnetic resonance is becoming an increasingly used examination in cardiology, since it greatly improves the accuracy of diagnosing of many heart diseases. At present magnetic resonance is the gold standard in assessing the volumes of the heart chambers and the systolic function of both ventricles. The possibility of detecting tissue characteristics to refine the diagnostics of different types of myocardial pathology is of essential importance. The authors summarize in the article the present knowledge about the use of magnetic resonance of the heart in the field of myocardial disease, i.e. cardiomyopathy and myocarditis. The first part of the review gives a general introduction into the topic of magnetic resonance examination of myocardial diseases, which is followed by a detailed descrip-tion of the benefits of this imaging method in dilated cardiomyopathy and myocarditis,in hypertrophic cardio-myopathy, and arrhythmogenic right ventricular cardiomyopathy.Key words fibrosis - cardiomyopathy - magnetic resonance - myocarditis - late contrast agent saturation.
