Background Information: Thyroid nodules are very common and may be detected by ultrasound in up to two thirds of asymptomatic adults. Over the last 2 decades there has been a dramatic rise in thyroid cancer incidence. Multiple professional societies have released guidelines aiming for standardization of thyroid nodules management. Recently updated American Thyroid Association (ATA) guidelines are widely accepted among clinicians, which makes it crucial for radiologists to be familiar with their management considerations. Recently published by American College of Radiology (ACR) Thyroid Imaging, Reporting and Data System (TI-RADS) complements clinical guidelines by facilitating standardized thyroid nodule description to enhance interdisciplinary communication.

Educational Goals/Teaching Points: Participants learn about epidemiology and pathophysiology of thyroid nodules and thyroid cancer, as well as predisposing factors. We review evidence-based thyroid cancer management considerations; review 2015 ATA guidelines on thyroid nodule management; review Thyroid Ultrasound Reporting Lexicon proposed by ACR and standardized approach to sonographic characterization of thyroid nodules; provide a pictorial review of sonographic features of thyroid nodules and apply clinical and imaging guidelines in specific clinical scenarios; and review controversies in thyroid imaging and major sources of misinterpretations.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques: We illustrate sonographic appearances of thyroid nodules with malignancy risk stratification and provide a pictorial review of 2015 ATA guidelines and 2015 TI-RADS lexicon.

Conclusion: Accurate ultrasound characterization of thyroid nodules is essential for guiding nodule management. This exhibit covers what radiologists need to know about current concepts in thyroid nodules management and standardized reporting of imaging findings.
