Short name: P717, generic name: Gd-DOTA-dextran, central moiety: Gd
A Gd-DOTA-dextran derivative slow-clearance blood pool agent (MRI contrast agent) under development (preclin., Guerbet SA).

Short name: P760, chemical compound: tetraazacyclododecanetetraacetic acid (DOTA), central moity: Gd
P760 (Guerbet SA) is a low-diffusion gadolinium complex with a macrocyclic core based on a tetraazacyclododecanetetraacetic acid (DOTA) structure, which is substituted with bulky hydrophilic groups. The relaxivity of P760 at 0.47 T is very high compared to Gd-DOTA.

Short name: P792, generic name: Gadomeritol, preliminary trade name: Vistarem™, central moiety: Gd
A macromolecular Gd-DOTA derivate under development as a MRI blood pool agent with rapid clearance. Phase II of the clinical trials on P792 (Guerbet SA) will make it possible to validate the performance of this agent in the fields of angiography, myocardial perfusion and tumor characterization.
