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. |
