<sup>18</sup>F-Fluorothymidine-Pet Imaging of Glioblastoma Multiforme: Effects of Radiation Therapy on Radiotracer Uptake and Molecular Biomarker Patterns

<table>The normal brain shows intense uptake of FDG but not FLT. (a) Comparison of intracranial % injected dose (%ID) of <sup>18</sup>F-Fluorodeoxyglucose (<sup>18</sup>F-FDG) and <sup>18</sup>F-Fluorothymidine (<sup>18</sup>F-FLT) radiotracers in healthy nude/athymic mice. <sup>18</sup>F-FDG uptake is greater than <sup>18</sup>F-FLT in intact mouse brain.  (b) Visual comparison of <sup>18</sup>F-FDG-PET and <sup>18</sup>F-FLT-PET imaging in nude/athymic mice for comparison of intracranial radiotracer uptake (yellow arrows).</table>
