The role of ultrasound findings in the management of thyroid nodules with atypia or follicular lesions of undetermined significance

Atypia or follicular lesions of undetermined significance (AUS/FLUS) is a broad cytological category in the Bethesda system for classifying thyroid cytology. This study investigated the diagnostic accuracy of ultrasound (US) analysis of thyroid nodules with AUS/FLUS.
