| 中文摘要:目的 探究超声弹性成像对弥漫性毒性甲状腺肿(Graves病)与桥本甲状腺炎(Hashimoto's thyroiditis,HT)的鉴别意义。方法 选取2010年9月~2014年12月间在笔者医院初诊为Graves病和HT的患者共250例,分为Graves组(n=124)和HT组(n=126)。采用常规彩超观察并记录甲状腺体积、形态、回声特征、血流情况,采用弹性成像分析并记录甲状腺弹性评分、相对应变值平均值(average relative value,MEAN)和蓝色面积比例(area ration of lowstrain region,%AREA)。对比常规彩超与联合超声弹性成像的诊断准确率。结果 两组甲状腺体积、回声分级和血流分级差异无统计学意义(P>0.05)。Graves组以散在低回声为主,HT组以弥漫性低回声为主,有网格样强回声;Graves组收缩期峰值流速(PSV)、舒张末期流速(EDV)均大于HT组,差异有统计学意义(P<0.05)。弹性成像分析显示,HT组弹性评分、%AREA均大于Graves组,但MEAN小于Graves组,差异有统计学意义(P<0.05)。彩超联合弹性成像对Graves病、HT鉴别诊断准确率高于常规彩超组,差异有统计学意义(P<0.05)。结论 弹性成像能够提高超声诊断Graves病、HT的准确率。 |

| Abstract:Objective To investigate the value of ultrasound elastography in diagnosis of Graves disease and Hashimoto's thyroiditis. Methods One hundred and twelve patients with Graves disease and 108 patients with Hashimoto's thyroiditis(HT) were included in this study between September 2010 and December 2014 in our hospital. Thyroid size, shape, echo characteristics, blood condition were observed and recorded by color Doppler ultrasound. In addition, Elastic score, the average value of the relative strain(MEAN) and the blue area ratio(%AREA) were gained by ultrasound elastography. The diagnosis accuracy of color Doppler ultrasound and ultrasound elastography were compared. Results No significant difference was detected in thyroid size, echo characteristics and blood flow classification(P>0.05). Graves group was mainly charactered with scattered hypoechoic echo-based distribution, and HT group was mainly charactered with diffuse hypoechoic echo-based distribution. PSV, EDV in Graves group were significantly higher than those in HT group(P<0.05).Elastic score and%AREA in HT group were significantly higher, but MEAN in HT group was significantly lower. The diagnosis accuracy of combined ultrasound was significantly higher than that of color Doppler ultrasound(P<0.05). Conclusion Color Doppler ultrasound combined with ultrasound elastography may play a role in the diagnosis of Graves disease and Hashimoto's thyroiditis. |
