目的观察甲状腺微小乳头状癌应用彩超诊断的价值。方法 155例(165个结节)甲状腺微小乳头状癌患者,均采用GE730、ALOKAα10等彩色多普勒超声检测,观察甲状腺微小乳头状癌患者结节二维声像图特征,彩色多普勒超声检测血流分布特点及颈淋巴结转移情况。结果 155例(165个结节)甲状腺微小乳头状癌患者超声图像特征中A/T<1 6.06%、边界清晰21.21%、无微小钙化38.79%、内部回声均匀39.39%、周边回声有声晕为0少于A/T≥1 93.94%、边界模糊78.79%、有微小钙化61.21%、内部回声不均匀60.61%、周边无或不完整声晕100.00%的患者(P<0.05)。甲状腺微小乳头状癌(PTMC)患者颈淋巴结转移阳性6.06%明显低于淋巴结转移阴性93.94%,差异具有统计学意义(P<0.05)。结论甲状腺结节超声检测二维图像特征结合彩色多普勒超声检测,可提高甲状腺微小乳头状癌检出率。
Objective To observe the value of color Doppler ultrasonography in the diagnosis of small papillary thyroid carcinoma. Methods A total of 155 patients (165 nodules) with papillary thyroid carcinoma were examined by color Doppler ultrasound, such as GE730 and ALOKAα10, to observe the features of two-dimensional sonography of nodules in patients with thyroid papillary carcinoma. Color Doppler ultrasonography Detection of blood flow distribution and cervical lymph node metastasis. Results A / T <1 6.06%, clear boundary 21.21%, no microcalcifications 38.9%, internal echo average 39.39%, and peripheral echoes with sound halo of 155 (165 nodules) in patients with papillary thyroid papillary carcinoma. Less than 93.94% of A / T≥1, 78.79% of border obscure, 61.21% of slight calcification, 60.61% of internal echo unevenness, 100.00% of patients with no or incomplete peripheral halo (P <0.05). The positive rate of cervical lymph node metastasis was 6.06% in patients with thyroid papillary carcinoma (PTMC), which was significantly lower than that in lymph node metastasis (93.94%) (P <0.05). Conclusions Ultrasound examination of thyroid nodules with two-dimensional image features combined with color Doppler ultrasound can improve the detection rate of thyroid papillary carcinoma.
