Abstract

Abstract: The value of high-frequency ultrasound combined with color Doppler ultrasound parameters in the diagnosis of benign and malignant thyroid nodules was explored. Forty patients with thyroid cancer were selected as the observation group and 42 patients with benign thyroid nodules were selected as the control group.The parameters of high-frequency ultrasound combined with color Doppler ultrasound in patients with different N and T stages were compared between the two groups, and the data were statistically analyzed. The comparison of nodule morphology, boundary, echo and calcification ultrasound signs between the two groups was statistically significant (P<0.05). The A/T_C, A/T_L, TI-RADS classification scores, PSV, RI, and Adler blood flow classification scores of the observation group were higher than those of the control group (P<0.05). The AUC of each parameter combined diagnosis of malignant thyroid nodules was 0.902. The AUC of diagnosis N1 staging was 0.879, and the AUC of diagnosis Ⅲ+Ⅳ staging was 0.915. All of which were greater than any single parameter (P<0.05). It can be seen that the combination of high-frequency ultrasound and color Doppler ultrasound to observe the signs of thyroid nodules and A/T_C, A/T_L, TI-RADS grades, PSV, RI, and Adler grades can diagnose the nature of nodules. It can also assess the preoperative tumor stage of patients with malignant nodules, and provide a quantitative reference for clinical treatment and decision-making.
