Low-risk thyroid nodules safe to track with ultrasound
By Kate Madden Yee
It's safe to use ultrasound to track thyroid nodules that don't have suspicious features after fine-needle aspiration biopsy -- although nodules with intermediate or highly suspicious features should be evaluated with another biopsy, according to research in the February issue of the American Journal of Roentgenology.

Quantitative analysis may help classify thyroid nodules
By Erik L. Ridley
The echogenicity of solid thyroid nodules is often assessed qualitatively during evaluation on ultrasound. But this task can also be performed quantitatively, potentially offering a useful tool for determining malignancy risk, according to research presented at the RSNA 2017 meeting in Chicago.
