Comparison of diagnostic performance of the current score-based ultrasound risk stratification systems according to thyroid nodule size

A potential effective strategy for managing large nodules in the current score-based RSSs could be to rely solely on US categories rather than size thresholds for biopsy. Additionally, the diagnostic performance of small nodules showed higher sensitivity and lower specificity compared to large nodules before applying size thresholds for biopsy. These findings suggest a possible new management strategy for large nodules and provide a basis for the managing small nodules.
