This translational exploratory study reveals differing PD-L1 expression levels in patients using 68Ga-NK224 PET/CT imaging, indicating potential clinical relevance.
Supplementary Figure S6. Representative 18F-FDG and 68Ga-NK224 PET/CT maximum intensity projection images of patients with varying PD-L1 expression levels: Patient A: 18F-FDG SUVmax 15.3, 68Ga-NK224 SUVmax 8.2, PD-L1 TPS 80%; Patient B: 18F-FDG SUVmax 10.1, 68Ga-NK224 SUVmax 4.8, PD-L1 TPS 2; Patient C: 18F-FDG SUVmax 10.4, 68Ga-NK224 SUVmax 2.2, PD-L1 TPS <1%.
