Table 1.

Table shows CT26 tumour retention of [¹⁸F]AlF-NOTA-KCNA3P in vivo after ICI treatment evaluated by PET/CT. Data are shown as the mean %ID/g ± S.D. of control groups, treatment responsive tumours (TR) across treatment cohorts and treatment non-responders (TNR) (n = 10 mice/ group; * p < 0.05; ** p < 0.01, comparing TR to TNR).

Treatment Group	[18F]AlF-NOTA-KCNA3P Tumour Uptake (%ID/g ± SD)
Control	0.51 ± 0.19
Treatment Responsive tumours (TR) αPD1	0.87 ± 0.15 *
αPD1 + αCTLA4	1.30 ± 0.36 **
Treatment Non-Responders (TNR)	0.53 ± 0.20
