Caption: There were significant differences between benign and malignant nodules.
Significant differences were found in age of patients, diameter of nodules, echogenicity of nodules, calcification of nodules, shape of nodules, halo sign (all ). Significant differences were found between any two types of vascular patterns ( ). There was no significant difference in gender, solitary nodule or not, location of nodules and margin of nodules between benign and malignant nodules (all ).
