Figure 6.

Image-derived, decay-corrected time-activity curves (TACs). Data are the mean ± standard error of the mean for 2 mice injected with ¹²⁴I cT84.66 monoclonal antibody; the tumor weights at sacrifice on Days 7 were 40 and 190 mg. TAC shapes were determined from relative image intensities in serial positron emission tomography (PET) scans, whereas TAC amplitudes were normalized to agree with direct tissue assays performed postsacrifice after the final microPET scan. For some data points, the error bars are too small to be distinguished from the symbols representing the mean values.
