目的分析现代超声对结节性甲状腺肿的声像图特征,提高对结节性甲状腺肿的诊断准确率。方法对经病理证实的82例结节性甲状腺肿患者的结节大小、形态、边界、囊壁情况、晕环、内部回声、钙化、后方回声及结节周边及内部彩色声像图评价分析。结果 82例结节性甲状腺肿患者,其中61例甲状腺体积明显增大,21例甲状腺体积未见明显异常;67例呈多发性结节,15例为单发性结节,多发性结节为81.7%;59例未探及颈部淋巴结肿大,23例伴有颈部淋巴结肿大,淋巴结表现为规则、淋巴门结构显示清晰。176个甲状腺结节,其中126个表现形态规则,137个结节边界清晰,111个结节未见晕环,145个结节未见包膜,109个内部回声不均、可见无回声区,95个结节伴有粗大的弧形钙化斑。结论现代超声对甲状腺结构具有很高的分辨力,优于其他的影像检查技术设备,可为临床提供有价值的诊断依据。
Objective To analyze the sonographic features of nodular goiter by modern ultrasound and to improve the diagnostic accuracy of nodular goiter. Methods Totally 82 patients with nodular goiter confirmed by pathology were analyzed for nodule size, morphology, boundary, wall condition, halo, internal echo, calcification, posterior echogenicity, and peripheral and internal color sonography. Results Of the 82 patients with nodular goiter, the volume of thyroid in 61 patients was significantly increased, while the volume of thyroid in 21 patients showed no obvious abnormality. 67 patients had multiple nodules, 15 patients had solitary nodules, multiple nodules were 81.7%; 59 cases were not detected and neck lymph nodes, 23 cases accompanied by cervical lymph nodes, the rules of lymph nodes, lymphatic structures showed clear. 176 thyroid nodules, of which 126 were morphologically regular, 137 nodules clear boundary, 111 nodules no halo, no nodules 145 nodules, 109 internal echo uneven, visible anechoic area, 95 nodules with coarse curved calcifications. Conclusion Modern ultrasound has a high resolution of the thyroid structure, superior to other imaging techniques, which can provide valuable diagnostic evidence for clinical practice.
