Magnetic resonance imaging is fast emerging and dominant imaging modality in the assessment of cardiovascular diseases. It provides high resolution 3D images of cardiovascular structures in axial, coronal and sagittal planes, vertical long axis, horizontal long axis, short axis and three-chamber view. It has clinical applications: in diagnosing ischemic heart disease, comparison with other imaging modalities, cardiac masses, thrombi, and infections, hypertrophic cardiomyopathy, restrictive cardiomyopathy, myocarditis, pericardial disease, valvular disease etc. it helps to evaluate blood flow, pressure gradients, ventricular volumetrics and analyzing ventricular contractile function etc. but The disadvantages of cardiac MRI also there and include long scan times, making it unsuitable for unstable and uncooperative patients, higher cost, limited availability and incompatibility with pacemakers etc. From future perspective it is believed that real-time monitoring of electromagnetic catheter-directed radiofrequency ablations for treatment of atrial fibrillation.
