The predictive value of 18F-FDG PET/CT metabolic parameters for PD-L1 expression in esophageal squamous cell carcinoma
This retrospective study aimed to evaluate the predictive value of non-invasive 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) metabolic parameters for programmed death-ligand 1 (PD-L1) expression status in esophageal squamous cell carcinoma (ESCC)....
