Assessment
Primary outcomes	1. Examination of usefulness of each finding of the color Doppler ultrasound in benign/malignant diagnosis (univariate analysis and multivariate analysis). 2. Sensitivity, specificity and accuracy of the B-mode alone, and the combination of color Doppler and B-mode.
Key secondary outcomes	1. Sensitivity, specificity and accuracy of the B-mode alone, and the combination of color Doppler, B-mode and elastography. 2. Reproducibility of evaluators
