超声造影对鉴别甲状腺实性结节良恶性的诊断价值

Value of Contrast-Enhanced Ultrasound in Study of Malignant Solid Identification of Benign Thyroid Nodules

目的:通过观察甲状腺实性结节的实时造影增强模式,探讨对于鉴别结节良恶性的诊断价值。材料与方法对70例甲状腺实性结节进行超声造影检查,观察并分析造影增强模式,并与手术或穿刺活检的病理结果对照分析。结果:增强达峰期,良性结节多表现为整体或环形边缘,强度与甲状腺正常实质对比为等增强或高增强,而恶性结节多表现为不均匀低增强,两者差异具有统计学意义(P<0.05)。结论:超声造影对甲状实性结节良恶性鉴别诊断价值较高,结合常规彩色多普勒超声可提高甲状腺恶性病变的检出率。

Purpose Enhancement mode through real-time contrast observation of thyroid solid nodules, study for the differential diagnosis value of benign and malignant nodules diagnosis. Materials and Methods： Ultrasound angiography in 70 cases of thyroid solid nodules, observation and analysis of imaging mode, and pathology and operation or biopsy results were analyzed. Results Enhance the peak period, benign nodules more performance for the whole or the annular edge, strength and normal thyroid parenchyma contrast enhancement or high nhancement, and malignant nodules showed heterogeneous low enhancement, with significant difference （P 〈 0. 05）, Conclusion： Contrast enhanced ultrasound in differential value of high solid thyroid nodule diagnosis of benign and malignant, combined with conventional color Doppler ultrasound can improve the detection rate of malignant thyroid lesions.
