Figure 7From: Decreased defluorination using the novel beta-cell imaging agent [18F]FE-DTBZ-d4 in pigs examined by PET Computer-assisted delineation of the cortical (white) and trabecular (black) bone tissues in the vertebrae. Isocontour ROIs were generated by thresholding on CT images. In this example, the cortical and trabecular ROIs have average densities of 391 and 255 HU, respectively.Back to article page
