Regional tumor oxygen tension: fluorine echo planar imaging of hexafluorobenzene reveals heterogeneity of dynamics.


PURPOSE Therapeutic success could be enhanced if therapy were tailored to the characteristics of specific tumors. We have been developing novel approaches to measuring tumor oxygen tension in vivo, and recently reported a method based on 19F nuclear magnetic resonance (NMR) spin lattice echo planar imaging (EPI) relaxometry of hexafluorobenzene (HFB). We… (More)
