Abstract:
Objective To observe the value of diameter ratio for ultrasonic differentiation of benign and malignant thyroid nodules.Methods Totally 437 thyroid nodules in 341 patients with thyroid nodule diameter ≤15 mm were retrospectively enrolled and divided into ≤5 mm group(group A)with 128 nodules,＞5 mm and ≤10 mm group(group B)with 194 nodules and＞10 mm group(group C)with 115 nodules.Based on ultrasound images,the maximum anterior posterior diameter,left-right diameter and vertical diameter(denoted as A,T and L,respectively)of lesions were measured,and A/T,A/L and T/L were calculated.The nodules were compared among 3 groups,and the efficacy of the above indexes for differentiation of benign and malignant thyroid nodules were analyzed.Results A/T and A/L of malignant thyroid nodules were all larger than those of benign nodules in all 3 groups(all P＜0.05).In group A,the area under the curve(AUC)of A/T and A/L for distinguishing benign and malignant thyroid nodules was 0.831 and 0.848,respectively,in group B was 0.724 and 0.746,respectively,while in group C was 0.696 and 0.687,respectively,being not between each 2 groups(all P＞0.05).Conclusion Both diameter ratios A/T and A/L could be used in ultrasonic differentiation of benign and malignant thyroid nodules,especially for those with diameter ≤10 mm.
