摘要
The invention relates to specific relaxation agents for organs or pathologies, which can be used for modifying the contrasts in medical imaging by nuclear magnetic resonance.PPThese agents are constituted by a complex of a paramagnetic element having a biologically active ligand or a ligand coupled to a biologically active molecule and which is specific to an organ or pathology. Thus, they are selectively fixed to the organs and make it possible to modify the contrasts in imaging by nuclear magnetic resonance, due to the presence of the paramagnetic element, which modifies the relaxation times.P PFor example, when examining the kidney, the complex can be constituted by dimercaptosuccinate or gadolinium diethylene triaminopentaacetate, whilst gadolinium phytate is used in examinations of the liver.
