声触诊组织定量技术在桥本甲状腺炎中的应用

Application of virtual touch tissue quantification technique in Hashimoto's thyroiditis

目的探讨声触诊组织定量(VTQ)技术在桥本甲状腺炎诊断及鉴别诊断中的应用价值。方法 102例桥本甲状腺炎患者根据声像图特征分为不均质型、斑片型、弥漫型及结节型,50例甲状腺正常者作为对照组。VTQ技术测量甲状腺剪切波速度(SWV)。结果桥本甲状腺炎患者SWV为(2.32±0.43)m/s,对照组SWV为(2.04±0.38)m/s,差异有统计学意义(P<0.05);不均质型、斑片型、弥漫型及结节型SWV分别为(2.07±0.37)m/s、(2.25±0.40)m/s及(2.33±0.40)m/s、(2.64±0.48)m/s。斑片型、弥漫型、结节型的SWV较对照组亦增大,差异均有统计学意义(P<0.05)。桥本甲状腺患者不均质型、斑片型、弥漫型的SWV值较结节型小,差异均有统计学意义(P<0.05)。结论 VTQ技术对于桥本甲状腺炎诊断与鉴别诊断有一定的临床价值。

Objective To investigate the application value of virtual touch tissue quantification technique （VTQ） in diagnosis and differential diagnosis of Hashimoto＇ s thyroiditis （HT）. Methods One hundred and two cases of HT patients were included in this study,the case group was classified into four categories according to the ultrasonographic features： unevenness pattern, focal hypoeehoic pattern, asystematie hypoechoic pattern, and nodular pattern, and 50 volunteers with normal thyroid were enrolled as control group. The shear wave velocity （SWV） was measured by VTQ. Results SWV was （2.32±0.43）m/s in HT case group ,SWV was （2.04±0.38）m/s in control group,respectively. In four HT categories, SWV was （2.07±0.37）m/s, （2.25±0.40）m/s, （2.33±0.40） m/s and （2.64±0.48） m/s, respectively. The SWV assessed in healthy subjects was significantly lower than that in HT （P 〈 0.05）. Compared with control group,the SWV in HT focal hypoechoic pattern, asystematic hypoechoic pattern and nodular pattern were significantly higher （P 〈 0.05）. The SWV between HT unevenness pattern, focal hypoechoic pattern, and asystematic hypoechoic pattern had no significant difference （P 〉 0.05 ） ,while the SWV between HT nodular pattern and the other categories had significant statistical difference （P 〈 0.05）. Conclusion VTQ has clinical value for diagnosis and differential diagnosis of Hashimoto＇ s thyroiditis.
