Figure 3

Air/carbogen ratios of tumor 18FDG uptake for whole tumor VOI (squares), as determined with the 3D region growing program using a 30% threshold, and for the hottest part of the tumor (90% threshold). Tumor uptake ratios were corrected using derived input function data as per equation 2 and the 2nd injection activity was corrected for residual activity remaining as a result of the first injection.
