The role of magnetic resonance imaging (MRI) as a diagnostic tool of coronary arteries disease has increased over the last years. Cardiac magnetic resonance (CMR) is a preferable tool in assessment of ventricular mass and function, presence and size of post infarct scaring and anomalies of coronary arteries. CMR becomes also a useful method in evaluation of myocardial viability. Examination with gadolinium dye allows for evaluation of myocardial perfusion and viability. The extent of the post infarct late enhancement zone has an important prognostic value in the recovery of the left ventricle function. Dobutamine, adenosine or dypirydamol stress CMR becomes a promising noninvasive diagnostic modality in detection of coronary artery disease. At present coronary arteries magnetic resonance angiography is being developed as well as CMR spectroscopy.
