Objective: This study aims to compare 1-month’s efficacy and safety of single-session ethanol ablation and radiofrequency ablation for treating both purely cystic nodules and predominantly cystic thyroid nodulesMaterials and Methods: This short-term retrospective study was approved by the Ethics Committee of the Institutional Review Board of Danang Family hospital, and written informed consent for procedures was obtained for all patients. 39 patient...

Objective: The aims of this study are to evaluate the safety and efficacy of RFA in the treatment of benign thyroid nodule(s) and to find independent factors related to the volume reduction rate of the nodule(s).Materials and methods: This short-term prospective study from a single medical center was conducted on 93 benign thyroid nodules in 93 patients treated with RFA. Two basic techniques were used: the trans-isthmic approach, moving-shot technique. C...

Objective: To determine whether the Korean-Thyroid Imaging Reporting and Data System (K-TIRADS) 4 nodules can be subcategorized by ultrasonography (US)-based stratification of malignancy risk, and to evaluate the diagnostic performance of the modified biopsy criterion based on the subcategorization of the K-TIRADS 4 category in a multicenter cohort.Materials and Methods: A total of 1,541 K-TIRADS 4 nodules (≥ 1 cm) with final diagnoses were include...

The inclusion of the less aggressive follicular form of papillary thyroid cancer (PTC) is associated with an increase in the incidence of the condition, with the follicular variant of PTC being the most common of all variants. The majority of individuals with the encapsulated follicular variant of papillary thyroid carcinoma (EFVPTC) are treated as though they have classic thyroid cancer, despite the availability of mounting evidence to contradict the aforementioned. According...

Background: Some regrowing nodules after radiofrequency ablation (RFA) of symptomatic large benign thyroid nodules are revealed as malignancies in surgery. The aim of the study was to assess the ultrasound (US) characteristic of thyroid nodules diagnosed as cancer later, the predictive factors for cancer after RFA, and the prevention methods for these cancers to avoid RFA.Materials and Methods: The medical records of 22 thyroid nodules with 18 patients w...

Objective: To evaluate the impact of a decision support system (DSS) based on artificial intelligence (AI) -KoiosDS- on ultrasound (US) image analysis and risk stratification in thyroid nodules.Material and methods: Retrospective US study of all thyroid nodules with histologic (AP) result from June 2020 to December 2021. Diagnostic performance of US with ACR-TIRADS, by six endocrinologists and DSS, before and after the use of AI was evaluated.<p clas...

Objective: Preoperative iodine therapy due to toxic nodular goiter (TNG) is discouraged as iodine may cause an aggravation of hyperthyroidism. In Graves’ disease iodine has been used for a century but little data is available on iodine treatment in TNG. We aimed to examine if a short course of iodine treatment is safe to administer in TNG.Method: 20 patients with TNG with persistent subclinical to mild hyperthyroidism were included at our tertiary c...

Background: Active surveillance (AS) has been widely accepted as a safe option in the treatment of low risk papillary thyroid microcarcinoma (PTMC) in recent years on the basis that its prognosis is not inferior to immediate surgery. However, clinicians as well as patients are still hesitant in actually choosing AS over immediate OP as treatment. Our aim was to investigate the factors in choosing treatment options in low risk PTMC.Method: Seoul National ...

This study was conducted to investigate and compare thyroid ultrasonography (US) findings in pediatric patients with goiter and normal thyroid function with positive or negative thyroid autoimmunity. From 2000 to 2020, we reviewed initial thyroid US images in 33 autoimmune thyroid diseases (AITDs) patients and 52 non AITD patients. Our review of the images focused on thyroid parenchymal hypoechogenicity and heterogeneous echopattern subdivided into 2 groups according to severi...
