甲状腺占位性病变的彩色多普勒声像图特征与病理对照分析

目的分析甲状腺占位性病变超声声像图特征，旨在提高甲状腺占位性病变良恶性鉴别的准确率，尤其是甲状腺内单发结节的诊断。方法回顾性对照分析143例甲状腺肿块超声声像图特征与术后病理结果。结果①单发结节型28例．超声诊断正确率57．1％；②多发结节型56例，超声诊断正确率69．6％；③弥漫结节型59例，超声诊断正确率96．6％。超声造影检查对单发可疑恶性结节可提高诊断正确率为78．6％，对其他类型的诊断准确率提高不明显。结论甲状腺肿块超声声像图表现为极低回声、均匀低回声实性肿块，无明显包膜、声晕，内有微小钙化且无囊性变的，诊断为恶性肿块可能性大，超声造影对提高单发结节的良恶性鉴别具有统计学意义。

Contrast analysis between the features of color doppler ultrasonography about thyroid lesions and pathological results

Objective To analyze the features of thyroid nodules of ultrasonography,aimed at improving accuracy of benign and malignant about thyroid lesions,especially for single nodule in thyroid.Methods Review the features of ultrasonography about thyroid lesions and the pathological results after operation,a total of 143 patients.Results Ultrasound diagnostic accuracy is 57.1% about single nodule in 28 cases,it is 69.6% about multiple nodules in 56 cases,and 96.6% about diffuse nodules in 59 cases.Making radiography by ultrasound which one is considered to be malignant in single nodule,then accuracy is improved to 78.6%,for other types the improvement is not obvious.Conclusion Thyroid lesions which have low echo level,microcalcification,and no envelope,no acoustic halo,no cystic degeneration are considered to be malignant ones.Ultrasound radiography is considered to have statistic meanings in distinguishing benign and malignant about single nodule in thyroid.
