Abstract
Objective
The purpose of this study is to investigate the characteristics of papillary thyroid
carcinomas (PTCs) on color duplex sonography (CDUS).
Methods
We retrospectively reviewed 115 nodules (104 patients) with PTC confirmed by pathology
from February 1, 2005, to August 31, 2008. The size, border, calcification, echotexture,
hemodynamics (peak systolic velocity and resistance index) of the thyroid nodules
and cervical lymph nodes on CDUS were analyzed.
Results
There was a close relationship between the size of the nodule and the vascularity
of the thyroid carcinoma (P=.000). Microcalcification increased the suspicion for malignancy of the thyroid nodule.
A hypoechoic thyroid nodule with abundant internal vascularity, ill-defined border
and microcalcification was highly suggested PTC.
Conclusion
CDUS plays an important role in the early detection of PTC and cervical lymph node
metastasis, which would provide surgeons with valuable information for planning surgical
intervention. Mastering manifestations of PTC on CDUS will improve the accuracy in
the diagnosis of PTC. CDUS-guided fine needle aspiration of the thyroid nodule is
the standard in the diagnosis of thyroid carcinoma and metastasis pre- and postthyroidectomy.
