The purpose of this study was to assess the potential application of color Doppler sonography in thyroid imaging. Thyroid nodules and other thyroid pathology detected by color Doppler ultrasound and nuclear scintigraphy were compared in 115 patients. The majority of "cold" nodules demonstrated a peripheral rim of color flow and no internal color flow with color Doppler sonography. A large number of "hot" nodules demonstrated internal color flow. Color Doppler sonography was helpful in delineating nodules in otherwise inhomogeneous glands. We determined that color Doppler cannot reliably distinguish benign from malignant thyroid nodules; fine-needle aspiration biopsy remains the most accurate method in differentiating benign and malignant lesions. We suggest that color Doppler sonography plays only a limited role in the evaluation of nodular thyroid disease at this time. The color Doppler appearance of other thyroid disorders (including toxic multinodular goiter, Graves' disease, and thyroiditis) is discussed.
本研究的目的是评估彩色多普勒超声在甲状腺成像中的潜在应用。对115例患者通过彩色多普勒超声和核素闪烁显像检测到的甲状腺结节及其他甲状腺病变进行了比较。大多数“冷”结节在彩色多普勒超声检查中显示周边有血流环，内部无血流信号。大量“热”结节显示内部有血流信号。彩色多普勒超声有助于在其他方面不均匀的腺体中勾勒出结节。我们确定彩色多普勒不能可靠地区分甲状腺良性和恶性结节；细针穿刺活检仍然是鉴别良性和恶性病变最准确的方法。我们认为目前彩色多普勒超声在结节性甲状腺疾病的评估中仅起有限作用。还讨论了其他甲状腺疾病（包括毒性多结节性甲状腺肿、格雷夫斯病和甲状腺炎）的彩色多普勒表现。
