Short & Sweet: Technical Solutions to Minimizing Motion

Synopsis
Motion is a common cause of image quality degradation in pediatric MRI and comes from a variety of sources. Motion artifacts can lead to difficulty visualizing small structures, incorrect apparent diffusion coefficient calculations on DWI, ghosting and blurring artifacts, and the need to repeat individual sequences or an entire exam. This talk will review current techniques to decrease patient motion, including fast imaging techniques, motion-robust sequences, indications for anesthesia/sedation, and motion correction technology. These strategies can all help reduce motion degradation and improve image quality during pediatric MRI.
