Objective: To retrospectively analyze the adverse effects of high-intensity focused ultrasound (HIFU) in management benign uterine diseases.Materials and methods: From 2011 to 2017, 27,053 patients with diseases were treated HIFU 19 centers China. Among them, 17,402 had fibroids, 8434 adenomyosis, 876 caesarean scar pregnancies, 341 placenta accreta.Results: The median age, height, weight, BMI was 42 years, 158 mm, 56 kg, 22.5 kg/cm2, respectively. After treatment, 13,170 events observed....
Objective To compare the pregnancy outcomes between ultrasound-guided high-intensity focused ultrasound (USgHIFU) ablation and laparoscopic myomectomy (LM).Materials methods This study included 676 women with symptomatic uterine fibroids who wished to become pregnant underwent USgHIFU or LM at three hospitals in China from 1 May 2009 31 2018. The related information of delivery were followed up analyzed using chi-square test two-sided Student t-test.Results median follow-up duration was 5...
To investigate the therapeutic dose and long-term efficacy of high-intensity focused ultrasound (HIFU) ablation for different types uterine fibroids based on signal intensity T2-weighted MR images (T2WI).Four hundred one patients with a solitary fibroid treated HIFU were classified into four groups consisting extremely hypointense, isointense hyperintense fibroids. Each group was further two subtypes: homogeneous heterogeneous, homogeneity The follow-up results compared.There significant...
Abstract Alkali-activated Fly Ash-Slag Geopolymer (AAFS) is a novel green and sustainable cementitious material with broad application prospects in soil stabilization, mucky foundation prone to problems such as uneven settlement of the structural instability. However, most existing studies have focused on static characteristics stabilized soils while neglecting research its dynamic characteristics. Therefore, studying variation law elastic parameters AAFS-stabilized under extremely small...
Creating flexible materials with multi-dimensional security holds great promise for anti-counterfeiting labels in food, currency, and pharmaceuticals, but it is proven extremely challenging. Herein, we propose a photoresponsive liquid crystal polymer (LCP) film by incorporating polymerizable photoswitch into commercial LCP ultraviolet (UV) light exposure. Reversible photochromism can be observed between light- dark-red under UV visible irradiation alternatively, accompanying variation of...
Objective: To evaluate the shrinkage rate, symptom relief and improvement of quality life following ultrasound-guided high intensity focussed ultrasound (USgHIFU) for multiple uterine fibroids.Methods: From October 2015 to November 2016, 81 black women with symptomatic fibroids underwent USgHIFU. The number ranged from 3 9. rate fibroids, severity score were evaluated Magnetic resonance imaging (MRI), fibroid (UFS-QOL) questionnaire used evaluation.Results: mean age patients was 35.3 ± 5.9...
Objective To develop a novel scoring system based on magnetic resonance imaging (MRI) for predicting the difficulty of ultrasound-guided high-intensity focused ultrasound (USgHIFU) ablation uterine fibroids.
Objective To explore the effect of oxytocin on uterine fibroids treated by ultrasound ablation. Methods Eighty-two single points in 29 from 26 patients were sonicated with magnetic resonance imaging guided high intensity focused before and after using oxytocin. The required total energy, sonication time to reach 60 ℃ acoustic energy for increasing 1 temperature at point compared. Results Before intravenous infusion oxytocin, average was (5320 ±910) J it took (21 ±20) seconds sonicating a...
To compare the safety and efficacy of high-intensity focused ultrasound (HIFU) treatment for patients with internal or external adenomyosis based on magnetic resonance imaging (MRI) classification.A total 238 167 who received HIFU were enrolled. results adverse effects between compared.The time sonication significantly longer than that adenomyosis. The energy used EEF higher (p < 0.05). pre-HIFU median dysmenorrhea score in was 5 8 points, decreased to 1 3 points these two groups at 18-month...
The near-solid wall multi-bubble cavitation is an extremely complex phenomenon, and has strong erosiveness. melting point (about 3410 °C) of tungsten highest among all pure metals, its hardness also very high (its yield strength greater than 1 GPa). What would happen to wire under extreme conditions caused by collapsing bubbles at hydrostatic pressure? In this paper, we have studied the fracture process with diameter 0.2 mm mounted focus a standing acoustic wave produced spherical cavity...
To explore a new high-intensity focused ultrasound (HIFU) sonication strategy for cesarean scar pregnancy (CSP) and to compare the clinical effectiveness safety of this HIFU with conventional followed by ultrasound-guided dilation curettage (USg-D&C) CSP.91 patients CSP treated USg-D&C in People's Hospital Deyang City between January 2017 December 2019 were retrospectively reviewed study. Based on strategy, divided two groups: 44 exposed 'C-shape' layer around implantation location sac...
Objective To investigate the MRI features and clinical outcomes of unexpected uterine sarcomas in patients after high-intensity focused ultrasound (HIFU) ablation for presumed fibroids.Materials methods 15,759 consecutive who came HIFU treatment, from November 2008 to September 2019, fibroids were retrospectively reviewed. All had completed a pre-HIFU MRI. images independently analyzed interpreted by two radiologists every center.Results According T2WI hyperintensity, accompanied irregular...
Resolution of high intensity focused ultrasound (HIFU) focusing is limited by the wave diffraction. We have developed a spherical cavity transducer with two open ends to improve precision without sacrificing acoustic (App Phys Lett 2013; 102: 204102). This work aims theoretically and experimentally investigate frequency dependence field generated from ends. The device emits at ranging 420 470 kHz, measured fiber optic probe hydrophone. results shows that provides for HIFU treatment only in...
Bulk piezoelectric ceramics operating in thickness-stretch (TSt) modes have been widely used acoustic-related devices. However, the fundamental TSt waves are always coupled with other modes, and occurrence of these spurious bulk affects its performance. To suppress 1-3 composites promising candidates. theoretical modeling multiphase ceramic composite objects is very complex. In this study, a sample fabricated. The electrical impedance two samples compared. A simple analytical vibration mode...
