Background: Extrathyroidal extension is an important factor to determine the extent of thyroid surgery. The aim present study was evaluate usefulness high-resolution ultrasound (US) for predicting extrathyroidal papillary microcarcinoma (PTMC). Methods: This included a total 221 PTMCs in 181 patients. PTMC defined as carcinoma equal or less than 1 cm size. US findings, such contact and disruption capsule, were evaluated predict carcinoma. We calculated diagnostic accuracy odds ratio each...
The aim of this study was to evaluate the overall ultrasonographic features and clinical factors that contribute inadequate sampling in ultrasound-guided fine-needle aspiration biopsy (US-FNAB) thyroid nodules.From April 2008 December 2008, 4077 US-FNABs 3767 consecutive patients were reviewed. We evaluated clinical, ultrasound pathological analysed association between these samples. also compared sample rates according experience performing doctor.The rate 16·1% (654/4077). Univariate...
Purpose To investigate the value of combined use elastography and color Doppler ultrasonography (US) with B-mode US for evaluation screening US-detected breast masses in women dense breasts. Materials Methods This prospective, multicenter study included asymptomatic breasts who were referred between November 2013 December 2014. Eligible had a newly detected mass at conventional screening, which performed. The following outcome measures compared combination US, elastography, US: area under...
This study aimed to compare the diagnostic performance of contrast-enhanced digital mammography (CEDM) and magnetic resonance imaging (CEMRI) in preoperative evaluations, evaluate effect each modality on surgical management women with breast cancer.This single-center, prospective was approved by Institutional Review Board, informed consent obtained from all patients. From November 2016 October 2017, 84 patients who were diagnosed invasive carcinoma (69/84) ductal situ (15/84), underwent both...
Thyroid ultrasonography (US) plays a key role in the diagnosis and management of thyroid-related diseases. The aim this article was to illustrate various pitfalls that can occur utilizing thyroid US techniques prevent them. In article, we present cases demonstrating common associated with equipment, performance, normal structures, misinterpretations, surrounding structures. Knowledge these areas is essential avoid misdiagnosis or improper disease management.
Ultrasonography (renamed from the Journal of Korean Society Ultrasound in Medicine January 2014), official English-language journal (KSUM), is an international peer-reviewed academic dedicated to practice, research, technology, and education dealing with medical ultrasound, Aims Scope:Ultrasonography ultrasound.It published four times per year: 1, April July October 1. Original articles, topical reviews, pictorial essays, notable case reports are covering state-of-the-art content. also...
Matrix metalloproteinases (MMPs) are matrix-degrading enzymes that play a pivotal role in aggressive behaviours, such as rapid tumour growth, invasion, and metastasis, of several types solid tumours. In particular, stromal MMP-2 plays important roles the progression malignant tumours, but most clinical studies have focused on tumoural -9 expression, not expression. One hundred seventy-seven cases diagnosed invasive ductal carcinoma breast between 2000 2005 were included this study....
We investigated the feasibility of using surgical clips as markers for tumor localization and their effect on imaging evaluation treatment responses after neoadjuvant chemotherapy (NAC).A total 16 breast cancers confirmed by needle biopsy in 15 patients were included this study from October 2012 to June 2014. Under ultrasonography (US)-guidance, placed prior NAC. Additional mammography, US, magnetic resonance examinations performed within 10 days before surgery. The time period marker...
Abstract Background Cytomegalovirus ( CMV ) infection is a major cause of morbidity in allogeneic hematopoietic cell transplant (allo HCT recipients. Little known about the epidemiology antiviral resistance pediatric population. We performed prospective study to assess impact drug‐resistant infections allo Methods Pediatric recipients who developed were consecutively enrolled from May 2009 April 2012. polymerase chain reaction amplification and sequencing analysis for UL 97 54 genes at...
The purpose was to present mean breast density of Korean women according age using fully automated volumetric assessment.This study included 5,967 screening normal or benign mammograms (mean age, 46.2 ± 9.7; range, 30-89 years), from cancer-screening program.We evaluated fibroglandular tissue volume, (VBD), and the results were 53.7 30.8 cm 3 , 383.8 205.2 15.8% 7.3%.The frequency dense breasts VBD by group 94.3% 19.1% 6.7% for 30s (n = 1,484), 91.4% 17.2% 6.8% 40s 2,706), 72.2% 12.4% 6.2%...
Fascin is an actin cross-linking protein, which regulates dynamics and filopodia or spike formation, as well the epithelial-mesenchymal transition, has been implicated in cell motility. Although, fascin pivotal mediating aggressive behaviour of various types cancer, its prognostic significance according to tumour stage yet be evaluated. Therefore, present study investigated expression 194 patients diagnosed with invasive ductal carcinoma breast between 2000 2005. protein levels were...
Triple receptor-negative (TRN) breast cancer is associated with high risk of recurrence and poor prognosis. The present study assessed the clinicopathologic characteristics ultrasound (US) features TRN cancers.Pathological biological data were reviewed for 558 patients treated at Kangbuk Samsung Hospital, between January 2003 December 2009. separated into non-TRN groups, based on results immunohistochemical prognostic panels. Clinical pathologic compared two groups. US features, including...
Quantitative magnetic resonance imaging (MRI) of cartilage has recently been applied to patients with osteoarthritis (OA). T2 mapping is a sensitive method detecting changes in the chemical composition and structure cartilage.To establish baseline values glenohumeral joint at 3.0 T compare among subjects without OA.The study involved 30 (18 women, 12 men; median age, 67 years; age range, 51-78 years) primary (n = 7) secondary OA 23) 34 (19 15 49 23-63 years).
