PET/CT Data of ⁶⁸Ga and ⁶⁴Cu NOTA-Y3-TATE and CB-TE2A-Y3-TATE Analogues in HCT116 SSTR2-Positive Tumor-Bearing Mice (n = 2 per group unless otherwise noted)

	⁶⁸Ga 1 h		⁶⁴Cu 1 h		⁶⁴Cu 4 h
	SUV	T:M	SUV	T:M	SUV	T:M
NODAGA-Y3-TATE	2.0 ± 0.1	18 ± 4.4	3.1 ± 1.3	324 ± 438	3.1 ± 0.8	26 ± 2.1
NOTA-β-Ala-Y3-TATE	0.81 ± 1.0	8.5 ± 7.2	4.0 ± 0.6	13 ± 4.9	3.1 ± 0.5	29 ± 34
NOTA-PEG₈-Y3-TATE^*	0.48	15	2.6 ± 0.6	8.9 ± 1.6	1.9 ± 0.4	38 ± 3.4
CB-TE2A-Y3-TATE^†	N/A	N/A	2.2 ± 0.6^†	34 ± 16^†	N/A	N/A

N/A = not available; PET/CT = positron emission tomography/computed tomography; SUV = standardized uptake value; T:M = tumor to muscle ratio.
