Sst-specific tissue uptake of [ 68 Ga]DOTATATE and [ 68 Ga]HA-DOTATATE. Effect of coinjection of 20 μg of unlabeled TOC per mouse (0.8 mg/kg) on the uptake of [68Ga]DOTATATE and [68Ga]HA-DOTATATE in sst-positive normal tissues and tumor of AR42J tumor-bearing nude mice at 60 min p.i. Data are means ± SD with n = 5 in the control experiment and n = 3 in the competition experiment.
