Summary for Patent: 5,130,120
Title: Paramagnetic DTPA and EDTA alkoxyalkylamide complexes as MRI agents
Abstract:Novel magnetic resonance imaging agents and methods which utilize complexes of paramagnetic ions with alkoxyalkylamide derivatives of diethylenetriaminepentaacetic acid ("DTPA") or ethylenediaminetetraacetic acid ("EDTA"). These novel imaging agents are characterized by excellent NMR image-contrasting properties and by high solubilities in physiological solutions. The complexes are represented by the following formula: ##STR1## wherein A is --CH.sub.2 CH.sub.2 -- or ##STR2## and M.sup.+z is a paramagnetic ion of an element with an atomic number of 21-29, 42-44 or 58-70, and a valence, Z, of 2 or 3; the R groups may be the same or different and are selected from the group consisting of -O.sup..crclbar. and lower alkoxyalkylamino groups having from 2 to about 6 carbon atoms, wherein the number of R groups -O.sup..crclbar. equals Z and the remaining R groups are lower alkoxyalkylamino, equal to 4-Z when A is --CH.sub.2 CH.sub.2 --, or 5-Z when A ##STR3##
