A total of 87 patients with HT complicated nodules admitted to Dongnan Hospital from Febru- ary 2016 to December 2019 were retrospectively selected as the research subjects. According to the pathological exami- nation results of thyroid nodule puncture, they were divided into malignant nodule group (30 cases) and benign nodule group (57 cases). The two-dimensional ultrasound imaging features (echo, morphology, aspect ratio, sound halo, micro- calcification, structure, boundary) and color Doppler flow imaging features (flow grade, resistance index value) were com- Results pared between the two groups. The proportion of hypoecho, irregular shape, aspect ratio≥1, acoustic halo and microcalcification in the malignant nodules group were higher than those in the benign nodules group, and the differ- P ences were statistically significant ( <).
