高频二维及彩色多普勒超声对慢性淋巴细胞性甲状腺炎的诊断价值

目的探讨慢性淋巴细胞性甲状腺炎的高频二维及彩色多普勒超声诊断价值.方法对78例经临床、实验室检查或手术病理证实的慢性淋巴细胞性甲状腺炎患者应用高频二维及彩色多普勒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78例慢性淋巴细胞性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,其内部回声改变分为三型,腺体实质偏低粗点状不均匀型;弥漫性高、等斑状回声,间有低回声型;腺体点状回声不均,其内有散在条状强回声,呈分隔状或网格状回声型.68例患者甲状腺血流明显丰富,甲状腺上动脉峰值流速高于正常.结论高频二维及彩色多普勒超声在慢性淋巴细胞性甲状腺炎的声像图具有明显特异性,有较高临床诊断价值.

Evaluation of Two- dimensional High Frequency Ultrasonography and Color Doppler Imaging in the Diagnosis of Chronic Lymphocytic Thyroiditis

Objective To evaluate two-dimensional high frequency ultrasonography and color Doppler imaging in the diagnosis of chronic lymphocytic thyroiditis.Methods Ultrasonic characteristics of seventy eight patients with chronic lymphocytic thyroiditis were observed with a high frequency transducer and color Doppler Imaging. All patients with chronic lymphocytic thyroiditis confirmed by the operation and pathology.Results All the patients showed diffused enlarged thyroid glands, especially isthmus of thyroid gland. There were three majority types of them: 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 color Doppler signal appeared in 68, and the peak systolic velocities of the superior thyroid artery were higher than normal.Conclusions We consider that the two-dimensional high frequency ultrasonography and color Doppler imaging findings are different and helpful in the diagnosis of chronic lymphocytic thyroiditis.
