摘要
目的探讨超声在甲状腺良恶性结节诊断中的应用价值。方法回顾性分析2012年12月至2015年2月经手术或穿刺活检病理证实的160例甲状腺结节患者超声诊断资料,其中良性结节82例,恶性结节78例,对比良恶性结节患者结节的位置、大小及形态、回声特点及结节内部结构、周边血流,并测量两组患者收缩期峰值流速（Vamx）、阻力指数（RI、）以及Adler分级。结果良性结节血流分级以0-Ⅰ级为主,而恶性结节以Ⅱ-Ⅲ级为主,良性结节钙化比率及RI、血流信号丰富比率均低于恶性结节患者,差异具有统计学意义（P〈0.05）;两组Vmax值与低回声比率对比无统计学差异（P〉0.05）,恶性结节患者形态规则比率、有晕环比率及边界清晰比率、囊实性比率均低于良性结节患者,差异具有统计学意义（P〈0.05）。结论超声可很好鉴别诊断甲状腺良恶性结节,诊断符合率高,对于诊断甲状腺良恶性结节具有十分重要的临床价值。
Objective To investigate the value of uhrasonography in the diagnosis of benign and malignant thyroid nodules in. Methods A retrospective analysis of our hospital from December 2012 to February 2015 with histopathologically confirmed were treated I60 cases of patients with nodular thyroid ultrasound diagnostic data, including 82 cases of benign nodules, malignant nodules 78 cases, compared to patients with benign and malignant nodules nodules position, size and shape, internal echo characteristics and nodular structure, surrounded by blood, and the two groups were meas2 ured peak systolic velocity（ Vamx）, resistance index （ RI, ） and Adler classification. Results Benign nodules blood polarization with 0-I class - based, and malignant nodules grade II -III mainly benign nodule calcification rate and RI, rich blood flow signals are lower than the rate in patients with malignant nodules （P 〈 0. 05 ）, the difference was statistically significant; Vmax values of the two groups with low echo contrast ratio of no significant difference（P 〉 0. 05）, in patients with malignant nodules were regular rate, there is a clear boundary halo ratio and the ratio of cystic ratios are lower than in patients with benign nodules （P 〉 0. 05 ）, the difference was statistically significant. Conclusion Ultrasound diagnosis may well benign and malignant thyroid nodules, has high diagnostic rate, for the diagnosis of benign and malignant thyroid clinical value is very important.
