Cardiac Magnetic Resonance Imaging Artifacts: Correction and Proper Interpretation

The aim of the study was to describe the cardiac magnetic resonance imaging artifacts and to develop ways to eliminate or interpret them. Materials and methods. 1,5 T contrast-enhanced cardiac magnetic resonance imaging was performed 156 patients with coronary artery disease. Technique of cardiac MRI included an assessment of left ventricular contractility, visualization of edema and acute myocardial damage, assessment of perfusion and myocardial scarring. Results. Various artifacts during cardiac MRI with contrast enhancement were visualized in almost every patient. The quality of cardiac magnetic resonance imaging depended on heart rate and blood flow in the cavities. In addition there were artifacts from the coronary stents, vascular clips, sternum's cerclage, as well as overlaying other organs and structures. During the study, were frequently observed “hyperintense endocardium” and “dark rim” artifacts which simulated endocardial edema and myocardial perfusion defect. Conclusion. The study found that despite the presence of certain artifacts that can affect the quality of the images and their analysis, there are effective ways to eliminate or reduce them. “Hyperintense endocardium” and “dark rim” artifacts can be distinguished from true pathology.
