应用彩色多普勒能量图观察分析诊断桥本氏病

目的应用CDE观察分析诊断桥本氏病，探讨桥本氏病的CDE特点，提高其诊断准确率。方法对57例经临床、实验室检查或手术病理证实的桥本氏甲状腺炎患者应用CDE超声检查甲状腺大小、回声，内部血流信号，甲状腺上动脉血流峰值流速，并对其结果进行分析。结果57例桥本氏甲状腺炎患者甲状腺均有不同程度增大，以侧叶前后径和峡部增大明显，腺体实质偏低粗点状不均匀；部分弥漫性高、呈等斑状回声，间有低回声；部分腺体点状回声不均，其内有散在条状强回声、分隔状或网格状回声。患者甲状腺血流明显丰富，甲状腺上动脉峰值血流速度高于正常对照组但低于甲亢组。结论CDE在桥本氏病的声像图具有明显特异性，有较高临床诊断价值，能为临床明确诊断提供重要依据。

Observation and Evaluation of Color Doppler Energy in the Diagnosis of Hashimoto''''s Thyroiditis

Objective To observe and evaluate color Doppler energy in the diagnosis of Hashimoto＇s thyroiditis, and discuss the peculiarity of Hashimoto＇s thyroiditis in CDE, and improve the accuracy of diagnosis. Methods Ultrasonic characteristics of 57 patients with Hashimoto＇s thyroiditis Were observed with CDE. All patients with Hashimoto＇s thyroiditis confirmed by the operation and pathology. Results All the patients showed diffused enlarged thyroid glands, especially isthmus of thyroid gland. Some of them showed thyroid glands with decreased and inhomogeneous echogram, some of them showed numerous hyperechoic and equal echoic nubble, some of them showed echogenicity separated by line. distinct increase of CDE signal appeared, and the peak systolic velocities of the superior thyroid artery were higher than normal, the peak systolic velocities of the superior thyroid artery in our group were increased but lower than that in the Graves＇one. Conclusion We consider that CDE findings are different and helpful in the diagnosis of Hashimoto＇ s thyroiditis.
