| 摘要: |
| 甲状腺乳头状癌（Papillary thyroid carcinoma, PTC）作为惰性内分泌肿瘤，发病率及检出率日益增高，其发生颈部淋巴结转移(Cervical lymph node metastasis, CLNM)率高达20-80%。超声诊断作为最基础的影像检查对中央区CLNM的检出有着重要地位。但由于超声特征存在假阴性，或者超声技术本身存在局限性，仍有转移的淋巴结在术前未能及时发现，这将影响外科手术术式的选择以及预后的评估。因此选择适合的超声诊断方式至关重要。本文即对目前几种常用的评估PTC患者CLNM的超声诊断方法的应用进展做出综述。 |

| Abstract: |
| As an indolent endocrine tumor, the incidence rate and detection rate of papillary thyroid carcinoma (PTC) has increased rapidly in the past few years. Although it belongs to indolent tumor with satisfactory prognosis, the cervical lymph node metastasis (CLNM) rate reaches up to 20-80%. As a basic imageological examination method, ultrasound technology plays an important role in the detection of central CLNM. However, due to the presence of false negative ultrasound features of lymph nodes in tumor metastasis, or the limitations of ultrasound technology itself, some metastatic lymph nodes were still not detected in time before preoperative ultrasound examination, which may affect the choice of surgical methods and prognosis evaluation. Therefore, it is very important to choose a suitable ultrasound diagnosis method. This article reviews the current application of several commonly used ultrasound diagnostic methods for assessing CLNM in PTC patients. |
