Thermal ablation using radiofrequency is a new, minimally invasive modality employed as an alternative to surgery in patients with benign thyroid nodules and recurrent thyroid cancers. The Task Force Committee of the Korean Society of Thyroid Radiology has developed recommendations for the optimal use of radiofrequency ablation for thyroid nodules. These(More)
OBJECTIVES To retrospectively compare the accuracy of fine-needle aspiration (FNA) and core-needle biopsy (CNB) for the diagnosis of thyroid malignancy METHODS We evaluated the results of FNA and CNB in 555 consecutive thyroid nodules with final diagnoses (malignancy 318, benign 237). All patients underwent FNA and CNB simultaneously for each nodule. We(More)
PURPOSE To compare volume reduction of single-session ethanol ablation (EA) and radiofrequency (RF) ablation for cystic thyroid nodule treatment. MATERIALS AND METHODS All patients gave written informed consent to participate in this prospective institutional review board-approved study. From May 6, 2010, to August 8, 2011, in this single-institutional,(More)
OBJECTIVE The objective of this retrospective study was to develop and validate a simple diagnostic prediction model by using ultrasound (US) features of thyroid nodules obtained from multicenter retrospective data. MATERIALS AND METHODS Patient data were collected from 20 different institutions and the data included 2000 thyroid nodules from 1796(More)
BACKGROUND The purpose of this study is to validate the generalizability of the efficacy and safety of radiofrequency (RF) ablation for treating autonomously functioning thyroid nodules (AFTN) in a large population multicenter study. METHODS This study included 44 patients from 5 institutions who refused or were not suitable for surgery or radioiodine(More)
BACKGROUND Percutaneous radiofrequency thermal ablation (RFA) has been reported as an effective tool for the management of benign thyroid nodules (BTN). However, large, randomized controlled trials (RCTs) are lacking. OBJECTIVE The aims of this study were to assess the volume reduction of BTN after a single RFA performed using the moving-shot technique(More)
OBJECTIVES To evaluate the outcomes of simple aspiration and ethanol ablation in the management of symptomatic nonfunctioning parathyroid cyst (PC). METHODS We performed simple aspirations for 12 PCs in 12 patients from March 1997 to June 2010. PC was diagnosed if the aspirated fluid was clear colorless and showed an elevated parathyroid hormone (PTH)(More)
OBJECTIVE The prevalence and features of the thyroid pyramidal lobe (TPL) on computed tomography (CT) have been reported, but no ultrasound (US) study has been found. The purposes of the current study were to assess the sonographic prevalence and features of TPLs and to compare the US and CT parameters of TPLs. METHODS From November 2012 to February 2013,(More)
Ketamine abuse is on the increase in Malaysia. Neurodegenerative change following ketamine use results in debilitating behavioural and cognitive dysfunctions. These changes are thought to be the consequences of network and cellular disorganization and degeneration in the brain involving areas such as hippocampus. Ketamine works by blocking NMDA receptor and(More)
Core needle biopsy (CNB) has been suggested as a complementary diagnostic method to fine-needle aspiration in patients with thyroid nodules. Many recent CNB studies have suggested a more advanced role for CNB, but there are still no guidelines on its use. Therefore, the Task Force Committee of the Korean Society of Thyroid Radiology has developed the(More)
