彩色多普勒超声对无痛性甲状腺炎与Graves病的诊断价值

Diagnostic value in color Doppler ultrasonograghy for painless thyroiditis and Graves disease

目的用彩色多普勒超声探讨无痛性甲状腺炎和Graves病的诊断特征。方法 48例因心悸,怕热多汗,手抖等症状患者测定T3、T4和TSH,根据摄131碘试验分为两组:实验组1:无痛甲状腺炎组18例;实验组2:Graves病组30例。受试者接受彩色B超检查。结果实验组血清T3、T4均高于正常组;TSH低于正常组;实验组1摄131碘率低于正常对照组;实验组2摄131碘率高于正常对照组;实验组1甲状腺体积增大,内部呈均质低回声,有散在回声点,分布于甲状腺内,甲状腺边界模糊。实验组2甲状腺体积增大,包膜边界清晰,血流信号丰富,呈"火海征"。结论摄131碘试验对于鉴别无痛性甲状腺炎与Graves病有重要价值,彩色B超检查也有诊断性特征。

Objective To fine out the diagnostic characteristics between painless thyroiditis and Graves disease in B ultrasonograghy.Methods 48 cases with painless thyroiditis and Graves disease were divided into two groups（Group 1 with painless thyroiditis.Group 2 with Graves disease.） according to radioactive iodine uptake test whose B ultrasonograghy was performed then.Results Serum T3 and T4 levels rose up and TSH droped down in 48 cases of patients feedback.The radioactive iodine uptake test in group 1 was low and in group 2 was high comparing with control group.Group 1 in B ultrasonograghy showed that there were characteristic features of enlargement and diffused or limited low echoes.And thyroid was ill-defined and obscured.Group 2 showed the characteristic features of thyroid enlargement,sharply defined and rich blood flow signal as Flames sea sign.Conclusions Thyroid iodine uptake test is very important to diagnose painless thyroiditis and Graves disease.B ultrasonograghy also shows characteristic value to diagnose painless thyroiditis.
