The purpose of this study was to assess the potential application of c
olor Doppler sonography in thyroid imaging. Thyroid nodules and other
thyroid pathology detected by color Doppler ultrasound and nuclear sci
ntigraphy were compared in 115 patients. The majority of ''cold'' nodu
les 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 determin
ed that color Doppler cannot reliably distinguish benign from malignan
t thyroid nodules; fine-needle aspiration biopsy remains the most accu
rate method in differentiating benign and malignant lesions. We sugges
t that color Doppler sonography plays only a limited role in the evalu
ation of nodular thyroid disease at this time. The color Doppler appea
rance of other thyroid disorders (including toxic multinodular goiter,
Graves' disease, and thyroiditis) is discussed. (C) 1995 John Wiley a
