What is the role of color flow Doppler ultrasonography in the diagnosis of amiodarone-associated thyroid dysfunction?

Answer

Color flow Doppler ultrasonography visualizes the amount of blood flow within the thyroid. However, the accuracy of this tool is limited by the proficiency of the sonographer.

Pattern 0 (absent vascularity, gland destruction) is associated with type 2 AIT.
Patterns 1-3 (with vascularity) are associated with type 1 AIT.
