Comparison of receiver operating curves between radiomics signature and striatum uptake ratio of the putamen. a The AUCs for the test dataset 1of the radiomics signature and SUR_putamen were 0.990 (95% CI, 0.976–1.00) and 0.980 (95% CI, 0.951–1.00), respectively (P = 0.302). b The AUCs for the test dataset 2 of the radiomics signature and SUR_putamen were 0.986 (95% CI, 0.967–1.00) and 0.929 (95% CI, 0.879–0.979), respectively (P = 0.041).
