## Abstract Liposomes are generally thought of as being useful for entrapping drugs within their internal aqueous space. When used with MR contrast agents, this has the drawback that water flux across the membrance bilayer is limiting to contrast enhancement. This can be partially overcome by makin

Abstract
Recent work on the development of liposomal magnetic resonance (MR) contrast agents has yielded structures with higher overall relaxivity than that of other nanoparti‐cles of similar diameter. Liposomes incorporating membrane‐bound complexes of manganese (“memsomes”) produce greater hepatic enhancement per micromole of metal ion than either ferrite particles or paramagnetic chelates. Memsomes also hold promise for targeting of sites outside the liver. Work is in progress to take these agents into clinical trials.

## Abstract We describe a well‐tolerated blood pool contrast agent with extended reclrculatory half‐life based on paramagnetic polymerized liposomes (PPLs). PPLs were constructed from a new type of polymerizable lipid molecule that has a derivative of gadopentetate dimeghimine as the hydrophilic he
