目的探讨高频超声在甲状腺囊实性结节良、恶性鉴别中的应用价值。方法回顾性分析经手术证实的25例囊实性甲状腺癌与70例良性囊实性甲状腺结节术前声像图特征,并仔细检查颈部有无异常肿大淋巴结,分析良恶性甲状腺囊实性结节声像图特征的异同。结果囊实性甲状腺癌与良性囊实性甲状腺结节实性部分回声、边界、边缘、形态、钙化、纵横比(A/T)、实性部分血流情况、颈部淋巴结转移等比较,差异均有统计学意义(P<0.05),而结节位置的差异无统计学意义(P>0.05)。结论分析甲状腺囊实性结节的超声声像图特征可提高诊断准确率。
Objective To investigate the value of high-frequency ultrasound in the differential diagnosis of benign and malignant thyroid nodules. Methods Retrospective analysis of 25 cases of cystadenocarcinoma confirmed by surgery and 70 cases of benign cystic thyroid nodules preoperative sonographic features and careful examination of the neck with or without abnormal enlarged lymph nodes, analysis of benign and malignant thyroid cysts The Similarities and Differences of the Features of Sexual Nodules. Results Comparisons of cystic solid thyroid carcinoma with solid cystic thyroid nodules, such as echogenicity, borderline, margin, shape, calcification, aspect ratio (A / T), solidus blood flow and cervical lymph node metastasis (P <0.05), while there was no significant difference in nodule location (P> 0.05). Conclusion The analysis of ultrasonographic features of solid thyroid nodules can improve the diagnostic accuracy.
