Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Preclinical and clinical imaging</bold> of porous media or void spaces such as human lungs could be possible. In their Communication on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">page 11636 ff.</ext-link>, K. Kovtunov, E. Chekmenev et al. describe the 3D ¹H MRI of hyperpolarized flowing propane at relatively short times with microscale spatial resolution and a large imaging matrix. The hyperpolarized propane was prepared by using a Rh/TiO₂ catalyst with Rh particle size of 1.6 nm. This highly stable catalyst allows for preparation of nontoxic asphyxiant hyperpolarized propane gas to potentially enable robust preclinical and clinical 3D molecular imaging.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh12z6fxh6" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
