ABSTRACT

Cardiac magnetic resonance (CMR) imaging has emerged as a leading imaging technology for the diagnosis of cardiovascular disease. CMR can provide a wealth of diagnostic information in one examination, simply by changing software parameters, and without any modifications to the hardware. For example, in one examination, CMR can provide high-quality images showing ventricular function, myocardial perfusion and viability, valve function, and cardiovascular anatomy. However, acquisition of high-quality diagnostic images for CMR is challenging, and the operator must often account for significant artifacts. This article describes many of the most common CMR sequences and their associated artifacts and strategies to compensate for them. In addition, motion-related artifacts and artifacts due to electrocardiogram gating will be discussed.
