Abstract    Local advanced thyroid carcinoma is difficult to treat in clinic.Ultrasound has the advantages of high resolution，accurate positioning and real-time imaging.It is the preferred imaging method for diagnosis，follow-up and evaluation of thyroid carcinoma patients. Ultrasound provides the size and location of the lesion and whether the invasion of the surrounding organs and cervical lymph node metastasis，which can real-time monitor disease progression.In addition，ultrasound-guided radiofrequency ablation can provide a definitive therapeutic effect for patients with advanced thyroid cancer who cannot undergo surgery.

Key words: thyroid carcinoma, ultrasound, advanced thyroid carcinoma

摘要：

局部晚期甲状腺癌是临床治疗难点，颈部局部病灶及周围组织器官浸润范围的精准评估对于病人的治疗方案的选择具有重要意义。超声具有高分辨率、定位准确、实时成像的优势，是甲状腺癌病人诊断、随访、疗效评估的首选影像学方法。对于局部晚期甲状腺癌，超声可提示原发或继发病灶的大小、位置，帮助判断浸润范围包括颈部淋巴结转移区域、原发或继发病灶与被膜、气管、食管等局部重要器官的关系，实时监测判断疾病进展。另外，对于不能手术的晚期甲状腺癌病人，超声引导下射频消融可发挥明确的治疗作用。
