CD274 and non-small cell lung carcinoma: In conclusion, this radiomics study based on [18F]FDG PET/CT radiomics features before treatment showed that the prediction model could predict PD-L1 expression status and provide a convenient, noninvasive and relatively accurate method for clinicians to identify patients who can benefit from anti-PD-L1 immunotherapy in NSCLC to guide the clinical immunotherapy of patients with NSCLC.
