Introduction: Thyroid nodule is a common disease that is found in 50% of the adult population; of total, 5% of thyroid nodule cases are diagnosed as thyroid cancers. Thyroid ultrasonography is the most sensitive diagnostic imaging method for the diagnosis of thyroid cancer. The ultrasonographic findings that indicate malignancy are taller than wider, speculate margins, marked hypoechoic lesion, microcalcification, and macrocalcification. In contrast to findings indicating pure...

Background: Radiofrequency ablation has recently been used for the treatment of benign thyroid nodules, with outstanding results. However, in most related studies, smaller nodules (<2 cm) were included and the procedure was usually performed by a radiologist or surgeon. Therefore, this study evaluated the efficacy and safety of radiofrequency ablation for nodules >2 cm performed by an endocrinologist with several years of experience performing fine-needle aspiration cy...

Background: Most thyroid nodules are benign therefore, they are commonly only monitored. Only a few studies are available on the natural progression/regression of benign thyroid nodules, and large-scale studies on the subject are non-existent. So we identify factors that affect the size of benign thyroid nodules and to predict the potential nodule size through a model.Methods: Between January 2001 and December 2011, 2,469 benign thyroid nodules (1,564 pa...

Objective: To evaluate computed tomography (CT) features for diagnosing metastatic cervical lymph nodes (LNs) in patients with differentiated thyroid cancer (DTC) and propose CT-based risk stratification system modified from the Korean Thyroid Imaging Reporting and Data System (K-TIRADS) guidelines.Materials and Methods: A total of 463 LNs from 397 patients with DTC who underwent preoperative CT staging and US-guided fine needle aspiration of LNs were in...

Objective: To evaluate the effectiveness and safety of ultrasound-guided RFA for symptomatic distant metastasis of DTC.Methods: The medical records of 12 patients who underwent RFA for palliative treatment of 18 symptomatic distant metastases from thyroid cancer between January 2008 and December 2020 were analyzed. All patients were assessed for their degree of discomfort, and were evaluated periodically as outpatients, clinically, and by imaging and ser...
