OBJECTIVE The purpose of our study was to provide new sonographic criteria for fine-needle aspiration biopsy of nonpalpable solid thyroid nodules. MATERIALS AND METHODS Sonographic scans of 155 nonpalpable thyroid nodules in 132 patients were prospectively classified as having positive or negative findings. Sonographic findings that suggested malignancy(More)
PURPOSE To develop a practical thyroid imaging reporting and data system (TIRADS) with which to categorize thyroid nodules and stratify their malignant risk. MATERIALS AND METHODS The institutional review board approved this retrospective study, and the requirement to obtain informed consent for the review of images and records was waived. From May to(More)
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)
BACKGROUND A homozygous mutant (ALDH2*2/*2) of the gene for mitochondrial aldehyde dehydrogenase 2 (ALDH2) at codon 487 was reported to be associated with myocardial infarction (MI) among Japanese men. However, such an association has never been studied in a Korean population. METHOD The subjects consisted of 122 men (60-81 y) with MI recruited randomly(More)
PURPOSE To retrospectively evaluate the diagnostic performance of power Doppler ultrasonography (US) in depicting vascularity and to determine whether the combination of vascularity and suspicious gray-scale US features is more useful in predicting thyroid malignancy than are gray-scale features alone. MATERIALS AND METHODS This was an institutional(More)
BACKGROUND Extrathyroidal extension is an important factor to determine the extent of thyroid surgery. The aim of the present study was to evaluate the usefulness of high-resolution ultrasound (US) for predicting the extrathyroidal extension of papillary thyroid microcarcinoma (PTMC). METHODS This study included a total of 221 PTMCs in 181 patients. PTMC(More)
Preoperative prediction of lateral lymph node metastasis (LNM) is important to prevent recurrence; however, there are few published data in predicting factors of lateral LNM before surgery. The present study investigated the factors affecting LNM in patients with papillary thyroid microcarcinoma (PTMC). A retrospective cohort study was conducted with data(More)
Corn silage was dried, ground, and then extracted with 0.1 M ethylenediaminetetraacetic acid. The filtrate was applied to a FumoniTest immunoaffinity column. Fumonisins were derivatized with naphthalene-2,3-dicarboxaldehyde, separated on a C(18) liquid chromatographic column, and detected by fluorescence. The detection limits for fumonisin B(1), fumonisin(More)
OBJECTIVE The purpose of this study was to evaluate the diagnostic performance of conventional sonography combined with sonographic elastography for differentiation between benign and malignant breast lesions and to assess the diagnostic performance with two types of interpretation criteria for sonographic elastography. METHODS For this study, we included(More)
PURPOSE To evaluate clinical aspects and imaging features of complications encountered in the treatment of benign thyroid nodules with radiofrequency (RF) ablation. MATERIALS AND METHODS Institutional review board approval was obtained for this retrospective study, and informed consent was waived. From June 2002 to September 2009, 1459 patients underwent(More)
