桥本甲状腺炎二维及彩色多普勒超声诊断分析

目的探讨二维及彩色多普勒超声对桥本甲状腺炎的诊断价值。方法回顾分析经病理检查确诊的26例桥本甲状腺炎患者，根据二维超声及彩色多普勒血流特点分为弥漫肿大型、结节肿大型及局限性桥本病三型。结果26例桥本甲状腺炎中弥漫肿大型16例，结节肿大型7例，这23例双侧甲状腺体积较正常明显增大，内部回声减低，部分呈网络样改变，病变部位血流信号丰富。局限性桥本病3例，表现为不均匀低回声区内血流信号丰富，肿大不明显。结论二维超声及彩色多普勒超声可以对桥本甲状腺炎正确分型。

Color doppler ultrasonography diagnosing hashimoto's thyroiditis

Objective To evaluate the diagnostic value of color Doppler ultrasonography in the Hashimoto's thyroiditis.Methods Twenty-six patients with Hashimoto's thyroiditis were divided into three groups according to the two-dimensional ultrasonography and color Doppler imaging: group 1,diffused enlarged Hashimoto's thyroiditis(HT),group 2,nodular enlarged TH,group 3,focal hypoechoic HT.Results Most HT lesions showed diffused enlarged glands,with decreased intraecho and inhomogeneous echogram of meshwork(except those patients with focal hypoechoic HT).All the cases in our group had CDFI hypervascularity.Conclusion CDFI is helpful in diagnosis and classification for HT types.
