Background
Considering the importance of the thyroid gland and the high prevalence of thyroid diseases, it may be surprising how unexcited radiologists are when a thyroid study appears on the worklist. A possible explanation is that the thyroid gland is rarely presented in a holistic, integrated manner in which information is built up from the normal anatomical and physiological basis to an overview of the different diseases with clinical, pathological, and multimodality imaging correlation. The goal of the exhibit is to fill this void in a simplified, interactive manner.

Educational Goals / Teaching Points
This exhibit presents a simplified overview of thyroid anatomy and physiology; simplified classification of thyroid diseases from the imager’s perspective; review of the major imaging modalities (focus on ultrasound and scintigraphy); and review of major disease entities and the societal guidelines.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
After basic illustrative discussion of thyroid structure and function (including review of the thyroid function tests and antibodies), the major diseases will be presented in the typical manner in which they are encountered by imagers. Thyroid imaging is usually obtained in one of two scenarios: 1) suspected thyroid disease based on clinical symptoms (hyperthyroidism, hypothyroidism, palpable mass, risk of disease) or 2) thyroid disease detected on prior imaging (diffuse disease such as “thyroiditis” versus focal disease such as “nodule follow up”). Multimodality overview will include nuclear medicine diagnostic and therapeutic approaches, sonography, and incidental findings on CT/MRI and other modalities. The explanations will be richly intermixed with carefully selected interactive board-style educational cases, which are aimed at both trainees preparing for board exams and radiologists reviewing for their MOC examinations.

Conclusion
An integrated perspective on thyroid disease will help imagers improve diagnostic acumen and communication with referring colleagues.
