Impact of the ultrasonography assessment method on the malignancy risk and diagnostic performance of five risk stratification systems in thyroid nodules
Abstract:Purpose
Ultrasonographic (US) assessment methods may affect the estimated malignancy risk of thyroid nodules. This study aimed to investigate the impact of retrospective and prospective US assessments on the estimated malignancy risk of US features, classified categories, and diagnostic performance of five risk stratification systems (RSSs) in thyroid nodules.
Methods
A total of 3685 consecutive thyroid nodules (≥ 1 cm) with final diagnoses (retrospective dataset, n = 2180; prospective dataset, n = 1505) wer… Show more
