Abstract
There is provided a contrast medium composition comprising magnetically responsive particles and a physiologically tolerable, incompletely hydrated viscosity enhancing agent.
Claims12
A contrast medium composition for administration to a patient for MR imaging comprising a pulverulent mixture of superparamagnetic, ferrimagnetic or ferromagnetic particles together with a physiologically tolerable viscosity enhancing agent, such that following dispersion of said composition in a physiologically tolerable carrier fluid it may be administered to said patient with the viscosity of the composition increasing after such administration.
A diagnostic contrast agent kit comprising a plurality of superparamagnetic, ferrimagnetic or ferromagnetic particles and, packaged separately thereto, a physiologically tolerable viscosity enhancing agent in pulverulent form.
