Magnetic resonance (MR) imaging has revolutionized imaging of the entire musculoskeletal system. Using commercially available machines, the physician can generate a strikingly detailed picture of virtually any part of a patient’s anatomy, displayed in any orientation, without the risks of ionizing radiation. The physical principles governing MR imaging are quite complex; fortunately, the practitioner who performs clinical imaging does not need to understand all of them fully. Nevertheless, a knowledge of some basic principles is invaluable when designing imaging studies to ensure patient comfort and safety, as well to generate high-quality images, which in turn will improve diagnostic accuracy. The same information will influence decisions regarding equipment purchases. This chapter reviews these principles, stressing those that are unique to the foot and ankle. Readers interested in a more rigorous discussion of the detailed physics of MR imaging can consult one of several comprehensive texts dedicated to the subject. 1,2.
