Synopsis

Body MRI is complicated by the presence of multiple sources of physiological motion, including respiratory, cardiovascular, peristaltic, and bulk patient motion. If unaddressed, these sources of motion can lead to multiple artifacts, particularly ghosting and blurring. Motion artifacts can also lead to bias and poor precision in quantitative MR methods. This educational talk will review the major challenges of motion in body MRI, as well as existing and emerging solutions. Importantly, this talk will attempt to outline the benefits and drawbacks of each motion mitigation method.
