Another step forward for methods for studying renal oxygenation

Abstract

All available methods for assessing renal oxygenation are limited either in terms of their temporal or spatial resolution, their ability to quantify tissue oxygen tension (PO₂), or in the settings in which they can be applied. Kodama and colleagues have developed a new method that utilizes dynamic nuclear polarization magnetic resonance imaging and an oxygen-sensitive paramagnetic agent (OX63). This new method generates quantitative maps of renal tissue PO₂ in millimeters of mercury.
