三维能量多普勒超声诊断甲状腺结节性质的研究进展

Research progresses of three dimensional power Doppler ultrasound in diagnosis of thyroid nodules

甲状腺结节为颈部常见疾病,超声是鉴别甲状腺结节性质的常用方法。彩色多普勒超声可反映甲状腺结节内部血管分布及血流情况,且三维超声等新技术的发展也增加了鉴别诊断的准确率。三维能量多普勒超声(3D-PDUS)可反映结节内部血流信息,比二维断面血流显示更加精确,并且可以定性、定量判断结节内部血流情况,为临床判断甲状腺结节性质提供新的参考依据。

Thyroid nodule is a common diseases of neck, which property is usually identified by ultrasound examination. Color doppler ultrasonography can reflect the distribution of blood vessels and blood flow within the nodules. And with development of new technologies, three-dimensional ultrasound increase the accuracy of identification. Three-dimension power doppler ultrasound （3D-PDUS） can reflect blood flow information within the nodule space, which is more accurate than two-dimensional ultrasound and it can be used to evaluate the blood flow in nodules qualitatively and quantitatively, provide a new reference for clinical diagnosis of thyroid nodule.
