目的 评价超声在结节性甲状腺肿并发腺瘤中的诊断价值 ,提高对甲状腺疾病多源性的认识。方法 对 4 0例甲状腺中的结节逐一进行仔细观察 ,评价二维图像和彩色多普勒血流图 (CDFI)的表现。结果 4 0例甲状腺病变共检出 15 7个结节 ,其中腺瘤结节 4 2个 ,结节性甲状腺肿结节 115个。实质性及囊实性腺瘤结节表现为包膜完整 ,周边有晕环并有环状包绕的血流信号。实质性及囊实性结节性甲状腺肿的结节表现为无包膜或包膜不完整 ,周边无血流或有短杆状血流显示。囊性腺瘤与囊性结节性甲状腺肿的鉴别诊断主要依据二维图像。结论 超声对提高甲状腺疾病多源性的认识 ,提高超声正确诊断率有重要的意义。
Objective To evaluate the diagnostic value of ultrasound in nodular goiter complicated with adenoma and to improve the understanding of the multi-source of thyroid disease. Methods 40 nodules in the thyroid were carefully observed one by one to evaluate the performance of two-dimensional images and color Doppler flow imaging (CDFI). Results A total of 15 7 nodules were detected in 40 thyroid lesions, including 42 adenoma nodules and 115 nodular goiter. Substantial and parenchymatous adenoma nodules showed complete capsule, surrounded by halo and a ring-shaped blood flow signal. Substantial and cystic solid nodular goiter nodules showed no capsule or incomplete capsule, peripheral blood flow or a short rod-shaped blood flow showed. Cystic adenoma and cystic nodular goiter in the differential diagnosis based mainly on two-dimensional images. Conclusion Ultrasound to improve the understanding of the multi-source of thyroid disease and improve the correct diagnosis of ultrasound is of great significance.
