FIGURE 3. Imaging of hNIS gene transfer using 76Br- and PET. (A) Upper panel demonstrates the high correlation between total counts per well and Ad-hNIS titer. Line denotes linear regression. Lower panel shows PET images and increasing signal as adenovirus titer is increased. (B) Upper panel demonstrates high correlation between total counts per well and activity of added 76Br-. Line denotes linear regression. Lower panel shows PET images. Signal increases as 76Br- activity is increased at a fixed viral titer. Data are representative of 2 separate experiments.
