摘　　要：目的观察可用于超声鉴别甲状腺良、恶性结节的径线比。方法回顾性纳入直径≤15 mm的甲状腺结节患者341例、共437个甲状腺结节,根据结节直径将其分为≤5 mm组(A组)128个、>5 mm且≤10 mm组(B组)194个及>10 mm组(C组)115个。基于超声图像,测量结节最大前后径、左右径和上下径(分别记为A、T和L),计算A/T、A/L、T/L,进行组间比较,评估不同径线比鉴别甲状腺良、恶性结节的效能。结果3组中,甲状腺恶性结节A/T和A/L均大于良性结节(均P<0.05)。以A/T和A/L鉴别A组甲状腺良、恶性结节的曲线下面积(AUC)分别为0.831和0.848,在B组分别为0.724和0.746,在C组为0.696和0.687;A/T与A/L的AUC差异均无统计学意义(P均>0.05)。结论A/T和A/L可用于超声鉴别甲状腺良、恶性结节,尤其针对直径≤10 mm者。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.
