Performances of the models for the differential diagnosis based on radiomics features only, and radiomics, age, sex and tumor location, and that of the three radiologists (Rad1-3). Values for the models are the mean presented with their 95% confidence intervals

	Radiomics	Radiomics + age + sex + location	Rad1	Rad2	Rad3
AUC	0.77 [0.71, 0.83]	0.84 [0.79, 0.90]	0.69	0.76	0.84
BCA	0.70 [0.65, 0.76]	0.76 [0.70, 0.82]	0.67	0.67	0.76
Sensitivity	0.66 [0.56, 0.76]	0.79 [0.71, 0.88]	0.74	0.90	0.78
