目的探讨二维及CDFI对甲状腺癌的声像图特征及其诊断价值。方法超声诊断甲状腺癌并经手术后病理证实的58例结果进行回顾性分析。结果 58例甲状腺中,单发甲状腺肿块40例(69.0%),多发性结节肿块18例(31.0%),肿块内合并微细钙化灶52例(89.6%),伴有颈部淋巴结转移30例(51.7%)。结论高频彩超检查甲状腺肿块呈低回声,边界不清,毛糙,未见包膜,其内多伴有细小钙化,多合并颈部淋巴结转移,是诊断甲状腺癌的重要指标。对单发微小结节及多发结节合并癌肿的诊断,需进一步分析探讨。
Objective To investigate the features and diagnostic value of two-dimensional and CDFI in thyroid cancer. Methods Ultrasound diagnosis of thyroid cancer and pathological findings of 58 cases were retrospectively analyzed. Results Of the 58 thyroid cases, 40 cases (69.0%) had single thyroid mass, 18 cases (31.0%) had multiple nodules, 52 cases (89.6%) had microcalcifications in the mass, and 30 cases had neck lymph node metastasis (51.7%). Conclusions High-frequency color Doppler ultrasound examination showed hypoechoic thyroid mass, unclear boundary, rough and no capsule. Most of thyroid masses were complicated with small calcification and multiple neck lymph nodes metastasis. It is an important index in the diagnosis of thyroid cancer. The diagnosis of single tiny nodules and multiple nodules complicated with cancer needs further analysis and discussion.
