To determine whether the size of thyroid nodules in ACR-TIRADS ultrasound categories 3 and 4 is correlated with the Bethesda cytopathology classification.
Thyroid nodules (566) subclassified as ACR-TIRADS 3 or 4 were divided into three size categories according to American Thyroid Association guidelines. The frequency of different Bethesda categories in each size range within ACR-TIRADS 3 and 4 classifications was analyzed.
Most nodules in both ACR-TIRADS classifications fell in the Bethesda 2 category, regardless of size (90.8% and 68.6%, ACR-TIRADS 3 and 4 respectively). The prevalence of Bethesda 6 nodules in the ACR-TIRADS 4 group was 14 times higher than in the ACR-TIRADS 3 group. There were no significant differences between nodule size and fine needle aspiration biopsy classification in any of the ACR-TIRADS categories.
Size does not appear to be an important criterion for indication of fine needle aspiration biopsy in thyroid nodules with a high suspicion of malignancy on ultrasound examination.
确定 ACR-TIRADS 超声类别 3 和 4 中的甲状腺结节大小是否与 Bethesda 细胞学分类相关。
根据美国甲状腺协会的指南，将 ACR-TIRADS 3 或 4 分类的甲状腺结节（566 个）细分为三个大小类别。分析每个 ACR-TIRADS 3 和 4 分类大小范围内不同 Bethesda 类别的频率。
无论大小如何，两种 ACR-TIRADS 分类中的大多数结节均属于 Bethesda 2 类（分别为 90.8%和 68.6%）。在 ACR-TIRADS 4 组中，Bethesda 6 结节的患病率是 ACR-TIRADS 3 组的 14 倍。在任何 ACR-TIRADS 类别中，结节大小与细针抽吸活检分类之间均无显著差异。
在超声检查高度怀疑恶性的甲状腺结节中，大小似乎不是细针抽吸活检的重要指征。
