TABLE 2.

Patients with ⁶⁸Ga-NODAGA-E[c(RGDyK)]₂ PET–Positive Lesions (TLR ≥ 2) According to WHO Classification of NENs

Uptake ratio	NET G1 (n = 21)	NET G2 (n = 55)	NET G3/NEC (n = 21)	All (n = 97)
TLR ≥ 2	13 (62%)	42 (76%)	19 (91%)	74 (76%)
TLR < 2	8 (38%)	13 (24%)	2 (10%)	23 (24%)

A tumor was defined as positive when the TLR, measured as lesion SUV_max–to–normal liver SUV_mean, was ≥ 2. Of the patients with NET G3/NEC tumors, 13 of 14 (93%) patients with NET G3 were positive and 6 of 7 (86%) patients with NEC were positive.
