<p>Use of a composition containing an image-modifying effective amount of an image enhancer, for preparing an image enhancer in the NMR imaging of a subject, the improvement which comprises employing as said enhancer a complex of an oxamine and a polyvalent paramagnetic metal, e.g. ferrioxamine. Novel complexes of trihydroxamic acids, optionally N-acylated, with polyvalent metals other than iron, are also described.</p> |
