Research progresses of three dimensional power Doppler ultrasound in diagnosis of thyroid nodules / 中国介入影像与治疗学

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.
