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).
