Relationship between SP142 PD-L1 Expression and ¹⁸F-FDG Uptake in Non-Small-Cell Lung Cancer

Figure 2

Representative images of ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT), showing variations in the maximum standardized uptake (SUVmax) value in relation to the expression level of programmed cell death ligand-1 (PD-L1). (a) PET/CT images showing FDG uptake by PD-L1-negative adenocarcinoma (ADC) (SUVmax 6.91, size 3.0 cm, and PD-L1 expression < 1%). (b) PET/CT images showing FDG uptake by ADC with low PD-L1 expression (SUVmax 11.37, size 3.1 cm, and PD-L1 expression 1–49%). (c) PET/CT images showing intense FDG uptake by ADC with high PD-L1 expression (SUVmax 19.49, size 3.0 cm, and PD-L1 expression > 50%).
