Purpose: To retrospectively evaluate the diagnostic accuracy of ultrasonographic (US) criteria for depiction benign and malignant thyroid nodules by using tissue diagnosis as reference standard. Materials Methods: This study had institutional review board approval, informed consent was waived. From January 2003 through June 2003, 8024 consecutive patients undergone US at nine affiliated hospitals. A total 831 (716 women, 115 men; mean age, 49.5 years ± 13.8 [standard deviation]) with 849...
Thermal ablation using radiofrequency is a new, minimally invasive modality employed as an alternative to surgery in patients with benign thyroid nodules and recurrent cancers.The Task Force Committee of the Korean Society Thyroid Radiology (KSThR) developed recommendations for optimal use tumors 2012.As new meaningful evidences have accumulated, KSThR decided revise guidelines.The revised guideline based on comprehensive analysis current literature expert consensus.
To evaluate clinical aspects and imaging features of complications encountered in the treatment benign thyroid nodules with radiofrequency (RF) ablation.Institutional review board approval was obtained for this retrospective study, informed consent waived. From June 2002 to September 2009, 1459 patients underwent RF ablation 1543 an system internally cooled electrodes at 13 centers, which were members Korean Society Thyroid Radiology. Numbers types major minor assessed.The authors observed...
The purpose of this study was to evaluate the efficacy radiofrequency ablation benign predominantly solid thyroid nodules by comparing findings in treatment and control groups.Thirty patients with normal function, each a (> 50%) nodule causing pressure symptoms or cosmetic problems, were assigned group (n = 15) undergoing single session 15). Thyroid volume, symptoms, concerns evaluated before during follow-up. Sonographically guided performed an internally cooled electrode (1-cm active tip)...
Thyroid nodules with fine-needle aspiration (FNA) readings of nondiagnostic or atypia undetermined significance (AUS), also referred to as follicular lesion (FLUS) are problematic for their optimal management. The usefulness performing a core-needle biopsy (CNB) clarify whether these benign malignant has not been established. purpose the present study was determine CNB provides better diagnostic information than repeat FNA (rFNA) in thyroid having AUS/FLUS readings.The Bethesda System...
An initial clinical assessment is described of a new, commercially available, computer-aided diagnosis (CAD) system using artificial intelligence (AI) for thyroid ultrasound, and its performance evaluated in the malignant nodules categorization nodule characteristics.Patients with decisive diagnosis, whether benign or malignant, were consecutively enrolled from November 2015 to February 2016. experienced radiologist reviewed ultrasound image characteristics nodules, while another assessed...
Papillary thyroid microcarcinoma (PTMC) usually has an excellent prognosis.To evaluate the three-dimensional structures of PTMCs, using serial neck ultrasonography (US) in patients under active surveillance.A retrospective cohort study.In total, 192 diagnosed with PTMC surveillance for >1 year were included a median 30-month follow-up. Changes tumor size evaluated not only maximal diameter but also volume.The age was 51.3 years and 145 (76%) female. The initial volume 5.5 mm 48.8 mm3,...
Objective: To assess the efficacy and safety of thyroid radiofrequency (RF) ablation for benign nodules by trained radiologists according to a unified protocol in multi-center study.Materials Methods: From 2010 2011, 345 from patients (M:F = 43:302; mean age ± SD 46.0 12.7 years, range 15-79) who met eligibility criteria were enrolled five institutions.At pre-ablation, volume was 14.2 13.2 mL (1.1-80.8mL).For 12 months or longer after treatment, 276 lesions, consisting 248 solid 28...
Purpose To compare the diagnostic performance of ultrasonography (US)-based fine-needle aspiration biopsy (FNAB) criteria from seven international societies in detection thyroid malignancy. Materials and Methods This study included a total 2000 consecutive nodules (≥1 cm) 1802 patients with final diagnoses January 2010 to May 2011. US features were retrospectively reviewed classified according categories defined by society guidelines. The US-based FNAB malignancy unnecessary rates calculated...
Background: Active surveillance has been introduced as a management option for low-risk papillary thyroid microcarcinoma (PTMC) due to its mostly indolent course. Methods: This was multicenter study of 370 PTMC patients who underwent active more than one year. The changes in volume and maximum diameter between initial last ultrasonography were evaluated identify the natural course during surveillance. Results: Patients' age at diagnosis 51 ± 12 years, 110 (30%) <45 years age. PTMCs 5.9 1.7...
Although ultrasonography (US) has an essential role in assessing the malignancy risk of thyroid nodules, a risk-stratification system not been established. The purpose this study was to develop clinically feasible US system--the Thyroid Imaging Reporting and Data System (TIRADS)--primarily based on solidity echogenicity nodules.From January 2010 May 2011, total consecutive 2000 nodules (≥ 1 cm) with final diagnoses were enrolled from database low high cancer volume institutions (1000 each...
Background: The primary goal of this interdisciplinary consensus statement is to provide a framework for the safe adoption and implementation ablation technologies benign thyroid nodules. Summary: This organized around three key themes: (1) safety techniques their implementation, (2) optimal skillset criteria proceduralists performing ablative procedures, (3) defining expectations success treatment option given its unique risks benefits. Ablation considerations in pre-procedural,...
Background: The longest reported follow-up for thermal ablation of papillary thyroid microcarcinoma (PTMC) is 5 years. We evaluated the long-term efficacy and safety radiofrequency (RFA) in patients with low-risk PTMC clinical more than 10 Methods: In this retrospective cohort study, we included who had years after ultrasound (US)-guided RFA (performed between May 2008 December 2013). Sixty-five consecutive 71 PTMCs were unsuitable surgery or declined included. Before RFA, all underwent US...
The purpose of this study was to evaluate the usefulness color Doppler sonography in differentiating benign from malignant cervical lymphadenopathy.We used 117 lymph nodes 105 patients. patients were pathologically and clinically confirmed have reactive lymphadenitis (n = 28), tuberculosis 17), lymphoma 14), metastasis 46). patterns hilar vascularity, central nodal peripheral vascularity assessed. highest resistive index pulsatility 116 measured spectral waveforms.
