Abstract
A diagnostic imaging agent is provided for use in conjunction with a magnetic resonance imaging system for the imaging of spacial oxygen distribution in tissue. The imaging agent is comprised of a complex of oxygen-17, a biologically acceptable liquid carrier, such as a perfluorinated compound, and an emulsifying agent, and wherein the agent has an average particle size of less than about 0.6 microns, and an ionic composition essentially equal to that of blood. Useful information can be obtained, and in certain instances, therapy administered, by a non-envasive imaging technique relative to tissue perfusion by .sup.19 F-NMR (imaging of .sup.19 F) and oxygen utilization by .sup.1 H-NMR (imaging of H.sub.2.sup.17 O as a metabolite).
