Abstract
A process for making a solution of a complex of an oxamine and a polyvalent paramagnetic metal comprising contacting a solution of the oxamine with (a) the insoluble hydroxide of the polyvalent paramagnetic metal in water, or (b) an alkoxide of the metal is a non-aqueous solvent, thereby to form a solution of a complex of the oxamine and the metal. The complex, preferably ferrioxamine, is an improved NMR image enhancer compared even with ferrioxamine made conventionally, characterized by a high LD.sub.50.
