Abstract

BARRANHAS, Adriana Dias et al. Cardiac magnetic resonance imaging in clinical practice. Radiol Bras [online]. 2014, vol.47, n.1, pp.1-8. ISSN 0100-3984.  http://dx.doi.org/10.1590/S0100-39842014000100006.

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.
