Nodular histiocytic/mesothelial hyperplasia (NHMH) is a very rare condition. It generally thought to be associated with repeated mechanical or chemical stimulation. This study reported NHMH papillary growth pattern in the ovary following high-intensity focused ultrasound (HIFU) treatment for uterine leiomyoma and adenomyosis. A 48-year-old female, who had history of undergoing HIFU 7 times aden...

High Intensity Focused Ultrasound guided by Magnetic Resonance Imaging (also known as MR-guided HIFU, MRgHIFU, or MRgFUS) is a therapy technique which uses focused ultrasound waves to heat and coagulate tissue deep inside the body without damaging intervening tissue and offers an novel, non-invasive treatment option for solid tumors. The Philips Sonalleve MR-HIFU system, initially released in 2...

High-intensity focused ultrasound (HIFU) has been used to ablate solid tumors and cancers. Because of the hypervascular structure tumor circulating blood inside it, interaction between HIFU burst vessel is a critical issue in clinical environment. Influences on lesion production potential rupture were investigated this study for efficiency safety ablation. An extracted porcine artery was embedd...

High Intensity Focused Ultrasound (HIFU) has been emerging as a new and effective modality in non-invasive thermal ablation for cancers and solid tumours. Although a theoretical model is available for calculating thermal field and the consequent lesion production, its computation is too time-consuming (~ 1 day) for HIFU treatment planning on the site. In this study, several approximations were ...

PURPOSE Ultrasound (US)-guided high intensity focused ultrasound (HIFU) has been proposed for noninvasive treatment of neuropathic pain and has been investigated in in-vivo studies. However, ultrasound has important limitations regarding treatment guidance and temperature monitoring. Magnetic resonance (MR)-imaging guidance may overcome these limitations and MR-guided HIFU (MR-HIFU) has been us...

Collateral damage and long sonication times occurring during high-intensity focused ultrasound (HIFU) ablation procedures limit clinical advancement. In this reserarch, we investigated whether the use of magnetic nano-particles (mNPs) can reduce the power required to ablate tissue or, for the same power, reduce the duration of the procedure. Tissue-mimicking phantoms containing embedded thermoc...

High-intensity focused ultrasound (HIFU) is a minimally invasive medical procedure which has shown considerable potential for a variety of therapeu­ tic applications. Some of the medical applications of HIFU include thermal ablation of tumors and uterine fibroids, vessel cauterization, thrombolysis, drug delivery, and gene activation (Curra and Crum [1]). HIFU ablation, unlike other minimally i...

Abstract High-intensity focused ultrasound (HIFU) is a promising therapy for thermal ablation and hyperthermia, characterized by its non-invasiveness high penetration depth. Effective HIFU thermo-therapy requires the ability to accurately predict temperature elevation corresponding dose distribution in target tissues. We report parametric numerical study of response soft tissue ultrasound. comp...

Objective: This study is to investigate the application of contrast-enhanced ultrasound in assessment of High-Intensity Focused Ultrasound (HIFU) in treating endometrioma. Methods: Totally 60 patients with endometrioma were included in this study, who underwent HIFU in our hospital from June 2014 to July 2016. At 3 d before treatment, and at 1, 3, 6, and 12 months after treatment, contrast-enha...

OBJECTIVE High-intensity focused ultrasound (HIFU) permits targeted homogeneous ablation of tissue. The objective of this phase 1 study was to evaluate the feasibility of HIFU ablation of small renal tumours under laparoscopic control. PATIENTS AND METHODS Ten kidneys with solitary renal tumours were treated with a newly developed 4.0 MHz laparoscopic HIFU probe. In the first two patients wit...
