甲状腺癌的超声图像分析

Analysis of Ultrasound diagnosis in thyroid carcinoma

目的评价超声检查对甲状腺癌的诊断价值。方法对手术病理证实的36例甲状腺癌的声像图进行分析,分析内容包括边缘形态,内部回声及钙化,周围组织情况等。结果典型甲状腺癌声像图特征表现为:边缘不规则,低回声不均质团块,微钙化,内部血流丰富,阻力指数高。结论超声检查对甲状腺癌有一定的诊断价值,但仍有局限性。

Objective To evaluate the diagnostic value of ultrasonography in thyroid carcinoma. Methods Thirty six cases with thyroid carcinoma confirmed by histopathology were analyzed and reviewed. The contour margin, internal echo and calcification of the nodules, the surrounding tissues and color Doppler ultrasonography were observed. Results The irregular contour, substantiality hypoecho, microcalcification, intranodular rich blood flow and high resistance were the typical appearance of the thyroid carcinoma. Conclusion The ultrasound is valuable for the diagnosis of thyroid carcinoma, but still has its limitation.
