Abstract
MRI uses powerful magnets which produce a strong magnetic field that forces protons to align with that field. When a radiofrequency current is then pulsed through the patient, the protons are stimulated, and spin out of equilibrium. When the protons return to their original state they release energy which is picked up by detectors and converted into an image. Gadolinium is often used to assess contrast enhancement.
