Relative inhibition (%) of [⁶⁴Cu]Cu-DOTATATE accumulation in MPC-mCherry tumors after co-injection of octreotide, [^natLu]Lu-DOTATATE and AN-238 at 0.2 µmol/kg as determined by different methods; (RD) radiotracer distribution; data are presented as means ± SEM; significance of differences was tested as compared to control; * p<0.05; † p < 0.01; ‡ p < 0.001.
