High-intensity focused ultrasound ablation of uterine localized adenomyosis

Current Opinion in Obstetrics & Gynecology, 2010
To introduce recent developments in a noninvasive treatment of using high-intensity focused ultrasound (HIFU) for ablating uterine localized adenomyosis, and to discuss their potential in this application.This literature roughly reviewed conservative therapy for uterine localized adenomyosis and emphasized using HIFU for ablating it.

Enhancement of ultrasound contrast agent in High-Intensity focused ultrasound ablation

Advances in Therapy, 2006
High-intensity focused ultrasound (HIFU) is becoming an increasingly attractive modality for ablation. Enhancement of HIFU is an important issue that has been discussed and investigated worldwide. Ultrasound contrast agents are considered to constitute an efficient medium for changing acoustic characteristics and improving energy deposition in the ...

High-Intensity Focused Ultrasound Ablation of Pancreatic Cancer

Digestive Disease Interventions, 2019
AbstractPancreatic cancer is one of the leading causes of cancer deaths, and many patients, with advanced disease, suffer from severe pain that can heavily affect their quality of life. In patients with advanced disease, an eminent role is played by percutaneous techniques, which cause tumor necrosis with a minimally invasive approach.

High Intensity Focused Ultrasound Ablation for Prostate Cancer: Whole Versus Partial Gland Ablation

Clinical Genitourinary Cancer, 2022
We compared the clinical outcomes between whole-gland ablation (WGA) and partial gland ablation (PGA) using the high-intensity focused ultrasound (HIFU) technique for localized prostate cancer (PCa).We retrospectively investigated 206 patients who underwent WGA or PGA for localized PCa.

Generating Uniform Lesions in High Intensity Focused Ultrasound Ablation

Proceedings of Meetings on Acoustics, 2012
High intensity focused ultrasound (HIFU) is emerging as an effective oncology treatment modality. Because of thermal diffusion from nearby spots, the lesion size will gradually become larger as HIFU progresses. However, uniform lesions with the least energy exposure are preferred by the physician in tumor ablation.

In Vitro Atrial Septal Ablation Using High-Intensity Focused Ultrasound

Journal of the American Society of Echocardiography, 2012
High-intensity focused ultrasound (HIFU) has been applied clinically as a noninvasive therapeutic tool. Atrial septostomy is a palliative treatment for pulmonary artery hypertension. The purpose of this study was to assess the feasibility of atrial septal ablation in vitro using HIFU.Fourteen sections of atrial septum from pig hearts were treated ...

High Intensity Focused Ultrasound (HIFU) Ablation

2012
The ideal cancer therapy not only induces the death of all localized tumor cells without damage to surrounding normal tissue, but also activates a systemic antitumor immunity. High intensity focused ultrasound (HIFU) has the potential to be such a treatment, as it can non-invasively ablate a targeted tumor below the skin surface, and may subsequently ...

High intensity focused ultrasound ablation of kidney guided by MRI

Ultrasound in Medicine & Biology, 2004
The effectiveness of magnetic resonance imaging (MRI) to monitor therapeutic protocols of high-intensity focused ultrasound (HIFU), in freshly excised pig kidney cortex is investigated. For high quality imaging, the pulse sequence fast spin echo (FSE) T1- and T2-weighted, and proton density were evaluated.

High intensity focused ultrasound ablation and antitumor immune response

The Journal of the Acoustical Society of America, 2013
The ideal cancer therapy not only induces the death of all localized tumor cells without damage to surrounding normal tissue, but also activates a systemic antitumor immunity. High intensity focused ultrasound (HIFU) has the potential to be such a treatment, as it can non-invasively ablate a targeted tumor below the skin surface, and may subsequently ...

Multiple High-Intensity Focused Ultrasound Probes for Kidney-Tissue Ablation

Journal of Endourology, 2005
To investigate kidney-tissue ablation by high-intensity focused ultrasound (HIFU) using multiple and single probes.Ultrasound beams (1.75 MHz) produced by a piezoceramic element (focal distance 80 mm) were focused at the center of renal parenchyma.
