目的探讨彩超联合超声弹性成像对弥漫性甲状腺肿(Graves病,GD)和桥本氏甲状腺炎(HT)的诊断价值。方法选取20例GD患者和20例HT患者,采用彩超联合超声弹性成像进行检查,观察甲状腺的大小、形态、血运、回声及弹性情况。结果两组患者甲状腺均明显增大,Graves组低回声分布分级以2级为主,HT组以3级为主(P<0.05);HT组85%呈网格样强回声分布,Graves组较少见(P<0.05)。Graves组收缩期峰值流速、舒张末期流速均较HT组快(P<0.05)。Graves组弹性图像分级以2级为主,占85%(17/20);HT组弹性图像分级以3级为主,占80%(16/20)。Graves组MEAN明显大于HT组,AREA%则较HT组小(P<0.05)。结论彩超联合超声弹性成像能为Graves病和桥本氏甲状腺炎的诊断提供更多信息,有效提高诊断准确率。
Objective To investigate the diagnostic value of color Doppler ultrasound and elastography in diagnosis of Graves’ disease (GD) and Hashimoto’s thyroiditis (HT). Methods Twenty GD patients and 20 HT patients were selected and examined by color Doppler ultrasound and elastography. The thyroid size, morphology, blood flow, echo and elasticity were observed. Results The levels of thyroid gland were significantly increased in both groups. Graves group was mainly grade 2 with hypoechoic distribution and grade 3 in HT group (P <0.05). In group HT, 85% Rare (P <0.05). The peak systolic and diastolic velocity of Graves group were faster than that of HT group (P <0.05). Graves group elastic image grading mainly in 2, accounting for 85% (17/20); HT group elastic image grading in 3, accounting for 80% (16/20). MEAN in Graves group was significantly higher than that in HT group, and AREA% was lower than HT group (P <0.05). Conclusion Color Doppler ultrasound imaging can provide more information for the diagnosis of Graves’ disease and Hashimoto’s thyroiditis, and effectively improve the diagnostic accuracy.
