Abstract
The invention relates to particulate contrast agents, especially contrast agents for MR imaging having a metal oxide core which is preferably superparamagnetic iron oxide. The particulate contrast agents are provided with a low coating density of a polyelectrolyte coating agent selected from structural polysaccharides and synthetic polymers, especially polyaminoacids. Unlike conventional coated particulates, the new particles have reduced or no effect on cardiovascular parameters, platelet depletion, complement activation and blood coagulation.
