桥本甲状腺炎的二维及彩色多普勒超声表现与分析

The expression and analysis of 2 dimensions and colour doppler sonography in Hashimoto thyroiditis

应用二维（２Ｄ）及彩色多普勒血流显像（ＣＤＦＩ）对２８例桥本甲状腺炎患者进行检查，结果表明：多数患者甲状腺弥漫肿大，尤以峡部明显，与正常人甲状腺体积相比，差异有显著性（Ｐ＜００５），腺体内部回声减低，可见“网格状”强回声，晚期甲状腺体积萎缩。ＣＤＦＩ：６０７１％（１７／２８）内部血流丰富，３９２９％（１１／２８）呈“火海征”，甲上动脉血流速度明显高于正常组（Ｐ＜００１），甲状腺体积萎缩者，内部血流减少，甲上动脉血流速度不高甚至减低。

Dimensions(2D) and Colour Doppler Sonography(CDFI) were used to examine 28 patients with Hashimoto thyroiditis. Results fhowed: ①The thyroid diffusely enlarged in most patients (apparently in isthmus); ② The thyroid volume statisticaly differed ( P <0 05), comparing to normal individuals; ③The echo in body of gland reduced and strong echo gitter appeared; ④The volume atrophy in adult thyroid was also found; ⑤CDFI: 60 1 percent (17/28) blood flows abundently in body of gland and 39 29 percent (11/28) appeared 'thyroid inferno'; ⑥The velocities of the thyroid artery were obviously faster than the normal group ( P <0 01). The body blood flows reduced in patients with thyroid volume atrophy and the velocities of the thyroid artery were slower, even reduced. It indicated that the expression of 2D and CDFI in Hashimoto thyroiditis can help to diagnose and identify this disease.
