摘要：
A magnetic resonance contrast agent has a medium, and a contrast structure dispersed in the medium. The contrast structure comprises a magnetic material arranged to create a local region of a local magnetic field such that nuclear magnetic moments of a material when arranged within the local region precess at a characteristic Larmor frequency about a total magnetic field in the local region while in use, the characteristic Larmor frequency being identifiable with the contrast structure, and the total magnetic field in the local region being a substantially spatially uniform magnetic field.
