“…bases. Additionally, the authors observed that, in the region, cardiac MRI has been utilized in patients of all age groups, and that it is most useful in the daily clinical practice to investigate, among others, myocardial ischemia under pharmacological stress and patients under suspicion of myocarditis Currently, cardiac MRI is considered the gold standard in the quantification of cardiac mass and volume, because of its low variability, high reproducibility and better accuracy as compared with other imaging methods utilized in cardiology (8,16) . However, the stratification of the study population according to LVEJ values is rather for illustrative purposes because of the population heterogeneity.…”

“…Cardiac magnetic resonance imaging (cardiac MRI) is a noninvasive cardiovascular investigation method with the greatest technical-scientific development over the last thirty years (1) . Currently, cardiac MRI is routinely utilized at different health centers (2) and the most frequent indications include the investigation of cardiomyopathies; myocarditis; stratification of risk for coronary artery disease (investigation of myocardial ischemia under pharmacological stress); and evaluation of myocardial viability, among others (3)(4)(5)(6)(7)(8)(9)(10) .…”

Objective To evaluate and describe indications, mainly diagnoses and cardiac magnetic resonance imaging findings observed in clinical practice. Materials and Methods Retrospective and descriptive study of cardiac magnetic resonance performed at a private hospital and clinic in the city of Niterói, RJ, Brazil, in the period from May 2007 to April 2011. Results The sample included a total of 1000 studies performed in patients with a mean age of 53.7 ± 16.2 years and predominance for male gender (57.2%). The majority of indications were related to assessment of myocardial perfusion at rest and under pharmacological stress (507/1000; 51%), with positive results in 36.2% of them. Suspected myocarditis was the second most frequent indication (140/1000; 14%), with positive results in 63.4% of cases. These two indications were followed by study of arrhythmias (116/1000; 12%), myocardial viability (69/1000; 7%) and evaluation of cardiomyopathies (47/1000; 5%). In a subanalysis, it was possible to identify that most patients were assessed on an outpatient basis (58.42%). Conclusion Cardiac magnetic resonance has been routinely performed in clinical practice, either on an outpatient or emergency/inpatient basis, and myocardial ischemia represented the main indication, followed by investigation of myocarditis, arrhythmogenic right ventricular dysplasia and myocardial viability.
