Background:Although ultrasound (US) features of papillary thyroid carcinoma (PTC) are well established, little is known regarding biological behavior according US features. We investigated whether there was a difference in between PTCs that did and not meet malignant criteria.
The purpose of this study was to identify perfusional subregions sharing similar kinetic characteristics from dynamic contrast-enhanced magnetic resonance imaging (MRI) using data-driven clustering, and evaluate the effect heterogeneity based on those patients' survival outcomes in various risk models. From two hospitals, 308 147 women with invasive breast cancer who underwent preoperative MRI between October 2011 July 2012 were retrospectively enrolled as development validation cohorts,...
Proper candidates to improve the effectiveness of molecular testing for thyroid nodules detected on ultrasonography (US) in a clinical setting are not well known. We aimed at evaluating effective indication and method BRAF(V600E) mutation analysis aspiration specimens according US features mutation-prevalent area.A total 244 patients with were prospectively classified as malignant nonmalignant based US. Thyroid any including spiculated margin, presence microcalcifications or...
This study was designed to assess whether artificial ascites has a heat-sink effect on the ablation zone for percutaneous radiofrequency (RFA) of hepatic tumors abutting diaphragm.We retrospectively assessed 28 patients who underwent RFA treatment single nodular tumor that abutted diaphragm from July 2000 December 2006. All ultrasound-guided using internally cooled electrodes. A 12 minutes applied 3-cm active-tip We divided into two groups basis introduced before RFA: Group consisted...
Background: Korea is no longer safe from the risk of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL); first reported case was a Korean woman in her 40s who had 7-year-history receiving an implant-based augmentation mammaplasty using textured implant.We conducted this study to discuss emerging crisis stakeholders and propose multi-disciplinary approach early detection its complications.Methods: We analyzed medical examination data that collected patients visited us between...
This study assessed the incidence and cancer rate of probably benign lesions detected on bilateral whole-breast screening ultrasound (US), which corresponded to US Breast Imaging Reporting Data System (BI-RADS) category 3, evaluated proper management those lesions.This was approved by Institutional Review Board in our institution, waived informed patient consent. We retrospectively reviewed images 1,666 patients who underwent as a supplemental test negative mammography or only. The...
Abstract Background It remains uncertain whether MRI identification of additional foci disease leads to improved outcome. We undertook a study evaluate the influence breast on early and long‐term Methods Among 1,271 patients undergone cancer surgery between January 2005 December 2006, 785 were attempted for BCS. Operative approach radiologic findings compared according use. reselected 615 with unilateral early‐stage treated BCS including RT. histopathologic characteristics outcomes Results...
Background There may be discordance between tumor size determined by magnetic resonance imaging (MRI) and that observed during pathologic analyses. Purpose To evaluate MRI-pathology concordance of in patients with invasive breast carcinoma. Material Methods Data from 307 carcinomas were analyzed retrospectively. Preoperative MRI was reviewed for size, lesion type, morphology, dynamic contrast-enhanced kinetics. compared measurements the analysis. Concordance defined as a difference diameter...
To evaluate whether preoperative breast dynamic contrast-enhanced (DCE) magnetic resonance (MR) imaging kinetic features, assessed using computer-aided diagnosis (CAD), can predict survival outcome and tumor aggressiveness in patients with invasive cancer.Between March December 2011, 301 women who underwent DCE MR for cancer, CAD data, were identified. All images retrospectively evaluated a commercially available system. The following parameters prospectively recorded each lesion: initial...
Most of the breast lesions show hypoechogenicity relative to fat on ultrasonography. The frequency and malignancy rate hyperechoic are not investigated in a large series.To evaluate sonography investigate sonographic characteristics that may predict lesions.Radiologic reports 16,416 patients who underwent between 2007 2008 were searched using "hyperechoic", "echogenic" or "heterogeneous echoic" describe lesions. Sonographic findings evaluated according Breast Imaging Reporting Data System...
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...
Purpose: Seroma formation at the surgical site is a common finding in postoperative breasts and should not be mistaken for tumor recurrence on imaging studies. The purpose of this study was to describe computed tomography (CT) findings seromas patients who underwent surgery breast cancer. Methods: CT were evaluated retrospectively 171 cancer from January December 2010. Chest recommended twice year first 3 years postoperatively annually thereafter; we incidence seroma images. Results: (mean...
To evaluate the effectiveness of follow-up with non-enhanced CT (NECT) in patients breast cancer.The present retrospective study included 1396 cancer. Group A no metastasis to diagnostic performance NECT detecting newly developed metastasis. B known hepatic accuracy for assessment metastasis.Group 895 (mean age 52.8 years). Among them, 145 had 160 metastases. The per-patient sensitivities diagnosing were 68.3 and 53.8% according two reviewers, while per-lesion 89.4 85.0%. Sensitivities bone...
Purpose: To investigate correlations of estrogen receptor (ER), progesterone (PR), and human epidermal growth factor type 2 (HER2) statuses with magnetic resonance imaging (MRI) features clinicohistological characteristics in patients invasive lobular carcinoma (ILC). Materials Methods: Data from 64 histologically confirmed ILCs were analyzed retrospectively. Preoperative breast MRI was reviewed for morphology dynamic contrast-enhanced kinetics the tumor. Pathologic reports ER, PR, HER2...
Spontaneous breast infarction is a very rare episode, representing about 0.1% of biopsied (1) and 0.3–1.5% fibroadenoma cases including the reported pregnant women (2-4). Although several have been in literature, we found only two reports that described mammographic findings an infarcted tumor involving five patients (1, 5). In present study, describe case spontaneous postpartum woman discuss mammography ultrasonography imaging findings.
Primary non-Hodgkin lymphoma (NHL) of the breast is a rare clinical entity, representing about 0.40.5% all malignancies and 1.7-2.2% extranodal NHL (1-3). We describe two cases primary lymphomas in middle aged woman discuss characteristics classical findings magnetic resonance (MR) imaging, MR spectroscopy diffusion weighted (DW) imaging as well mammography ultrasonography.
