Recent innovations in magnetic resonance, involving both hardware and software, that effectively deal with motion-whether inadvertent on the part of the patient or due to respiration and cardiac contraction-are reviewed, emphasizing major current advances. New technology involving motion sensing (kinetic, respiratory, and beat) is enabling simpler, faster, and more robust monitoring of the sources of motion. This information is being integrated, with new innovative imaging approaches, to effectively manage motion and its impact on image quality. Additional impact has been made by the use of compressed sensing and simultaneous multislice imaging, with these techniques maturing and being adopted to decrease scan time and thus the effect of motion. Guidance in terms of clinical use for techniques that effectively combat motion is provided, focusing on enabling faster and improved clinical scans. Magnetic resonance imaging is on the cusp of a major new leap forward in terms of image quality and clinical utility enabled by these technological advances.
