摘要
目的探讨彩色多普勒超声在甲状腺癌诊断及鉴别诊断中的应用价值。方法回顾分析甲状腺肿瘤患者64例,其中甲状腺癌33例,甲状腺腺瘤31例,全部经手术病理或组织活检证实。观察并比较分析两种病灶的形态、大小、分布、血流形态、动脉血流速度、阻力指数和血流分级。结果甲状腺癌病灶结节多为单发,内部回声减低或回声不均,沙砾样钙化多见,边界不规则,呈蟹足样或有明显毛刺状,结节后方多有声衰减。甲状腺腺瘤病灶结节内部回声减低,相对均质,囊性变多见,少有沙砾样钙化灶,边界规则并可见声晕。恶性结节血流信号丰富,多见穿入性血流,分布杂乱。良性结节中血流信号多分布于病灶的边缘,较规则,病灶内部血流较少。恶性病灶动脉血流速度高及阻力指数显著高于良性结节。结论彩色多普勒超声在甲状腺恶性结节诊断与鉴别诊断中有重要价值。
Objective To investigate the clinical value of color Doppler ultrasound in the differential diagnosis of thyroid carcinoma. Methods Sixty four patients with thyroid tumor, which were all pathologically confmned, were retrospectively analyzed. Among these patients there were 33 cases with thyroid carcinoma and 31 cases with thyroid adenoma. Observation and analysis were made on the morphology, dimention, distribution, blood signals, arterial velocity, resistance index and the grading of blood signals. Results Most of the malignant lesions were single with hypoechoic and heterogeneous echo, and with gravel calcification. There were irregular boundary and echo attenuation, there were also rich blood flow signals in the lesions and higher flow velocity and RI than that of benign lesions. On the other hand, most of the benign lesions were regular and homogeneous echo, rarely with gravel calcification. There were poor blood flow signals and low flow velocity and RI. Conclusion Color Doppler ultrasound is valuable in the differential diagnosis of thyroid carcinoma.
