Background:
Thyroid nodules diagnosed in children pose a greater risk of malignancy compared to those in adults. However, there is no ultrasound thyroid nodule evaluation system aimed at children. The objective of this research is to assess the diagnostic performance of the adult-based American College of Radiology Thyroid Imaging Reporting and Data System (ACR-TIRADS) and Chinese Thyroid Imaging Reporting and Data System (C-TIRADS) in pediatric thyroid carcinoma.
Methods:
The preoperative ultrasound images of 177 thyroid lesions in 136 pediatric patients aged 18 or younger who underwent thyroid surgery or fine needle aspiration (FNA) at our center from July 2017 to July 2022 were reviewed. The sonographic characteristics of pediatric thyroid carcinoma were compared and analyzed in contrast to benign nodules. All the nodules were evaluated by the ACR-TIRADS and the C-TIRADS respectively.
Results:
Ultrasound features such as solid composition (94.8%), hypoechogenicity or marked hypoechogenicity (94.8-95.7%) and microcalcification (78.3-84.3%) were more common in pediatric malignant nodules (P-values < 0.05). The areas under receiver operating characteristic curves (AUC) of the ACR-TIRADS and the C-TIRADS in diagnosing pediatric thyroid carcinoma were 0.903-0.906, 0.907-0.909 (P-value > 0.05). The interobserver agreement of both the ACR-TIRADS and the C-TIRADS was strong (weighted Kappa > 0.90).
Conclusions:
Both the C-TIRADS and the ACR-TIRADS owned great diagnostic performance and strong interobserver agreement in diagnosing pediatric thyroid carcinoma. However, a more complete and specific ultrasound evaluation system for pediatric thyroid nodules is still needed.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
