Methods for enhancing magnetic resonance imaging
First Claim
1. A method for enhancing magnetic resonance images of body organs and tissues which comprises administering to a mammal a composition comprising a substantially nontoxic manganese or gadolinium complex of a compound of the formula:
- ##STR4## wherein n and m=1, 2, 3 or 4, y=1, 2 or 3 and X is selected from the group consisting of O, S, CHOH and CHSH, in a sufficient amount to provide enhancement of magnetic resonance images of body organs and tissues.

Abstract
Substantially nontoxic manganese or gadolinium complexes of compounds of the formula: ##STR1## wherein n and m=1, 2, 3 or 4, y=1, 2 or 3, and x is selected from the group consisting of O, S, CHOH and CHSH, are useful for enhancing magnetic resonance images of body organs and tissues. Illustrative manganese and gadolinium complexes of such compounds include disodium [[ethylenebis(oxyethylenenitrilo)]tetraaceto]-manganese(II), disodium [[(2-hydroxytrimethylene)dinitrilo]-tetraaceto]manganese(II), sodium [[(2-hyroxytrimethylene)dinitrilo]tetraaceto)gadolinium(III).
