To evaluate the diagnostic performance of two-dimensional shear wave elastography (2D-SWE) in distinguishing malignant from benign thyroid nodules. A total of 331 focal thyroid nodules from 271 patients scheduled for fine-needle aspiration or thyroid surgery were included. After a routine conventional ultrasound evaluation, 2D-SWE examinations were(More)
OBJECTIVE To evaluate the diagnostic performance of shear wave elastography (SWE) in the differentiation of malignant and benign thyroid nodules with coexistent Hashimoto's thyroiditis (HT). STUDY DESIGN Case series with chart review. SETTING Tertiary general hospital. SUBJECTS AND METHODS From September 2012 to January 2014, conventional ultrasound(More)
To explore an effective noninvasive tool for monitoring liver fibrosis of children with biliary atresia (BA) is important but evidences are limited. This study is to investigate the predictive accuracy of supersonic shearwave elastography (SSWE) in liver fibrosis for postoperative patients with BA and to compare it with aspartate aminotransferase to(More)
OBJECTIVE The purpose of this meta-analysis was to summarize the evidence on the accuracy of various ultrasound findings for excluding a diagnosis of biliary atresia. MATERIALS AND METHODS We searched MEDLINE and the Web of Science databases for the period from January 1990 to May 2015. To be included, studies had to satisfy two criteria. First, the data(More)
Compressed air energy storage (CAES) is a commercial, utility-scale technology that provides long-duration energy storage with fast ramp rates and good part-load operation. It is a promising storage technology for balancing the large-scale penetration of renewable energies, such as wind and solar power, into electric grids. This study proposes a CAES-CC(More)
This study aimed to summarize the first experience with ultrasound-guided percutaneous ablation treatment (PAT) for recurrent hepatoblastoma (HB) after liver resection in children. From August 2013 to October 2014, PAT was used to treat 5 children with a total of 8 recurrent HB (mean size, 1.4 ± 0.8 cm; size range, 0.7-3.1 cm), including 4 patients with 7(More)
Metastasis of breast cancer into the gastrointestinal tract happens rarely. The diagnosis of this kind of disease is difficult because of the nonspecific symptoms and the long interval between primary manifestations and recurrence. Awareness of this condition may lead to an accurate diagnosis and an earlier initiation of systemic treatment, thus avoiding(More)

Visceral artery aneurysms have a potential possibility of rupture with life-threatening hemorrhage, and prompt detection and optimal treatment are required clinically. Actually, abdominal ultrasound plays a major role in detection of visceral artery aneurysms. Besides, the administration of contrast agents can highly improve the characterization of the(More)
OBJECTIVE To assess the value of voiding urosonography (VUS) with SonoVue in evaluation of vesicoureteral reflux. METHODS Thirty-six pediatric patients (72 pyeloureter units [PUUs]) suspected of vesicoureteral reflux underwent both VUS and fluoroscopic voiding cystourethrography (VCUG). The sensitivity of VUS and VCUG and their consistency in detecting(More)
