Abstract
An X-ray contrast composition comprising particles consisting essentially of a non-radioactive crystalline organic x-ray contrast agent having a surface modifier adsorbed on the surface thereof in an amount sufficient to maintain an effective average particle size of less than 400 nm, and a pharmaceutically acceptable carrier therefor is useful in x-ray diagnostic medical imaging methods. The agents can be delivered to a specific tissue or fluid site, for example, the blood pool, liver or spleen. In one embodiment involving intravenous administration, preferred compositions provide effective imaging of the blood pool for remarkably long times.
