| Abstract: |
| Magnetic resonance imaging （MRI） is a non-invasive molecular imaging modality, which plays an important role in clinical diagnosis. Non-lanthanide metal manganese （Mn） is of vital importance in cell biology and is one of the early reported examples of paramagnetic contrast agents used for MRI. This paper reviews the research progress of manganese （II）-based contrast agents in MRI, introduces the basic principles of MRI and the role of contrast agents, elaborates on the advantages and disadvantages, synthetic methods, and biomedical applications of diverse manganese （II）-based contrast agents. The performance optimization strategies of manganese （II） based contrast agents and the challenges they face in clinical applications were discussed in detail, and their future development trends were also prospected. |
