对131例甲状腺疾病进行了回顾性研究。探讨二维图像(2D)、彩色及脉冲多普勒超声(CD及PD)联合应用对各类甲状腺疾病的诊断价值。将病变组按病理、手术及T_3、T_4结果分为6组,即甲亢组、结节性甲状腺肿组(结甲)、甲状腺腺瘤组(腺瘤)、甲状腺炎组(甲腺炎)、桥本氏甲状腺炎组(桥本病)及甲状腺癌组(甲癌)。观察各组2D及CD特点,将各病变组PD血流指数与正常对照组进行两样本均数比较。结果显示86％腺瘤周边有动脉血管环绕;结甲的结节内无或仪有稀疏血流信号;甲亢者有典型的“火焰征”;甲癌血流速及阻力指数增加,且有动脉血管呈枝状自肿瘤边缘向内部延伸;甲状腺炎则有高流低阻表现。
131 cases of thyroid disease were retrospectively studied. To investigate the diagnostic value of two-dimensional image (2D), color and pulsed Doppler ultrasound (CD and PD) in the diagnosis of thyroid diseases. The lesions were divided into 6 groups according to the pathology, operation, T 3 and T 4 results, namely hyperthyroidism group, nodular goiter group, thyroid adenoma group, thyroiditis group, Hashimoto’s thyroiditis group (Hashimoto’s disease) and thyroid cancer group (A). The characteristics of 2D and CD in each group were observed. The PD index of each lesion was compared with that of the normal control group. The results showed that there were arterial vessels surrounding the tumor in 86% of the cases. There was no or no sparse blood flow signal in the nodules of the node; the typical “flame sign” in the hyperthyroidism; the blood flow velocity and resistance index of the carcinoma increased, Blood vessels dendritic extend from the edge of the tumor to the interior; thyroiditis has high flow and low resistance.
