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 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)
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)
The purpose of this series was to preliminarily evaluate the use of contrast-enhanced sonographically guided percutaneous thermal ablation in the evaluation and treatment of solid-organ bleeding by retrospectively analyzing 6 cases observed in clinical practice. Six patients who underwent contrast-enhanced sonographically guided thermal ablation for(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)

For successful gene therapy, it is imperative to accumulate therapeutic gene in tumor tissues followed by efficiently delivering gene into targeted cells. Ultrasound irradiation, as a noninvasive and cost-effective external stimulus, has been proved to be one of the most potential external-stimulating gene delivery strategies recently in further improving(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)
