Diagnostic significance of magnetic resonance imaging for myocardial damage of various genesis

Abstract

Purpose: to evaluate the diagnostic significance of magnetic resonance imaging in the differential diagnosis of ischemic heart damage and non-coronary myocardial diseases. Materials and methods: a retrospective analysis of medical documentation of 60 patients of cardiac departments of the Rostov Regional Clinical Hospital was conducted. Held a comparative analysis of the informativeness of the application of instrumental researchmethods (ECG, echocardiography, coronary angiography with leftventriculography and magnetic resonance imaging of the heart) among the patients with myocardial damage of different origins. Results: in patients with IHD, postinfarction cardiosclerosis, in most cases, the results of instrumental studies were diagnosed as having a diagnostic relationship. Conducted MRI of the heart was of decisive importance in the evaluation of the state of the myocardium after systemic thrombolysis or questionable ECG and EchoCG data and was also significant in the differential diagnosis of acute coronary syndrome and focal myocarditis. The results of MRI played an important role in determining the etiology of myocardial hypertrophy, in particular hypertrophic cardiomyopathy, and also helped in the case of differential diagnosis in the syndrome of cardiomegaly.Сonclusions: shown a high diagnostic value of magnetic resonance imaging with the use of contrast agents in the differential diagnosis of ischemic and noncoronary myocardial diseases.
