Quantifying the SUV 95 . SUV values within the lung are determined by semi-automated segmentation of the lung voxels from the pre-treatment staging PET/CT study (left). The cumulative distribution of SUV values is constructed from the voxel values within the lung ROI. The 80th, 90th, and 95th percentiles are obtained from these distributions to yield the corresponding SUV80, SUV90, and SUV95. The SUV95 is depicted graphically (right) for the example case, with the ROI ≥ SUV95 shown superimposed (middle).
