Fig. 3From: Multiparameter diagnostic model based on 18F-FDG PET metabolic parameters and clinical variables can differentiate nonmetastatic gallbladder cancer and cholecystitisDecision curve analyses (DCA) showed that, regardless of the threshold probability of a doctor or a patient, using the combined model (cholecystolithiasis plus fever plus CEA > 5 ng/ml plus SUVR) in our study to differentiate nonmetastatic gallbladder cancer from cholecystitis was more valuable than using SUVR alone. The x-axis represents the threshold probability, and the y-axis represents the net benefitBack to article page
