¹⁸F-Fluromisonidazole PET Imaging as a Biomarker for the Response to 5,6-Dimethylxanthenone-4-Acetic Acid in Colorectal Xenograft Tumors

Abstract

(18)F-FMISO PET could distinguish between different tumor responses to DMXAA treatment. However, a reduction in (18)F-FMISO SUV(mean) after DMXAA treatment was indicative of reduced perfusion and therefore delivery of (18)F-FMISO, rather than a reduction in tumor hypoxia.
