## Abstract An open phase III clinical trial of the oral contrast agent OMP (oral magnetic particles) was performed in 35 patients undergoing abdominal magnetic resonance (MR) imaging at 1.5 T with axial spin‐echo and gradient‐echo sequences. The diagnostic efficacy of OMP was examined by comparing

Nutation echoes are generated by radiofrequency (RF) pulses with an inhomogeneous amplitude, B 1 ؍ B 1 (r), in inhomogeneous magnetic fields, B 0 ؍ B 0 (r). The two gradients of strengths G 1 and G 0 , respectively, must be aligned in parallel for a maximum echo signal. After two RF pulses, two
