"This article covers an approach to interpreting ultrasound of thyroid nodules, largely to determine whether an FNA is required. However, please note that several professional societies have published formal assessment criteria to determine the need for FNA, which are covered in separate articles."

"while a halo around a well-marginated hypoechoic or isoechoic nodule is typical of a follicular adenoma 3, it is absent in >50% of benign nodules 2; what is more, up to 24% of papillary thyroid carcinomas may have a halo, be it complete or incomplete 2"
