Contrast enhanced ultrasound at first month: A feasible predictor for retreatment after benign thyroid nodule thermal ablation

Benign thyroid nodules (BTNs) are a common occurrence in the population [1]. The estimated prevalence of thyroid nodules in global is as high as 67 %, with nearly 90 % characterized as benign [2]. Clinical interventions typically deemed unnecessary in the majority of BTNs. However, palpable large BTNs necessitate treatment due to nodule-related compressive symptoms or cosmetic concerns [3]. Ultrasound (US)-guided thermal ablation (TA), encompassing modalities such as radiofrequency ablation (RFA…
