conclusions some of the noninvasive body contouring devices in animal and human studies such as cryolipolysis, rf, lllt and hifu showed statistical significant effects on body contouring, removing unwanted fat and cellulite in some body areas. however, the clinical effects are mild to moderate, for example 2 - 4 cm circumference reduction as a sign of subcutaneous fat reduction during total tre...

Objective: High Intensity Focused Ultrasound (HIFU) has been shown capable of ablating soft tissues in vitro and in vivo. However, mainly due to the lack of knowledge of the exerted radiation force in tissue, mechanical characterization of ablated tissues, particularly at very high HIFU powers, remains largely understudied. This study aims at quantifying the canine liver tissue viscoelastic pro...

BACKGROUND High-intensity focused ultrasound (HIFU) is considered to be an alternative to surgery. Extracorporeal ultrasound-guided HIFU (USgFU) has been clinically used to treat solid tumors. Preliminary trials in a small sample of a Western population suggested that this modality was safe. Most trials are performed in China thereby providing comprehensive data for understanding the safety pro...

Abstract Introduction and Objective: High-Intensity Focused Ultrasound (HIFU) is an FDA-approved procedure for the treatment of localized prostate cancer. HIFU destroys tumor tissue by noninvasively delivering ultrasonic energy, which rapidly heats targeted tissue. Prostate cancer has few tumor-infiltrating lymphocytes, are required antitumor immunity. The objective this study was to determine ...

HIFU is used in the treatment of cancer (prostate, breast) and uterine fibroma but not yet in TNs. This case report describes the first successful ablation of a toxic TN with HIFU. TSH and radioiodine scan normalization were achieved without complications and maintained for 18 months. HIFU treatment is a minimally invasive technique that may be an effective safe alternative to radioiodine or su...

The purpose of this study was to determine whether high-intensity focused ultrasound (HIFU) is an effective treatment for pancreatic cancer in an athymic nude mouse model. Female athymic nude mice (n=44) were inoculated subcutaneously with 5-7×10(6) SW1990 human pancreatic cancer cells. Thirty-six animals developed tumours and were randomly divided into three groups: HIFU (n=18), sham treatment...

BACKGROUND High-intensity focused ultrasound (HIFU) is a promising, non-invasive technique in treating benign thyroid nodules (TNs). The aim of this study was to evaluate the efficacy of HIFU to induce clinically meaningful shrinkage in benign predominantly solid TNs and to identify variables that influence or predict the magnitude of TN volume reduction. METHODS For each of ten subjects, HIF...

High-intensity focused ultrasound (HIFU) has been emerging as an effective and noninvasive modality in cancer treatment with very promising clinical results. However, a small vessel in the focal region could be ruptured, which is an important concern for the safety of HIFU ablation. In this study, lesion formation in the polyacrylamide gel phantom embedded with different tubing (inner diameters...

BACKGROUND Varicose veins and other vascular abnormalities are common clinical entities. Treatment options include vein stripping, sclerotherapy, and endovenous laser treatment, but all involve some degree of invasive intervention. The purpose of this study was to determine ex vivo the effectiveness of a novel hand-held, battery-operated, high-intensity focused ultrasound (HIFU) device for tran...

High intensity focused ultrasound (HIFU) or focused ultrasound surgery is a non-invasive technique for the treatment of cancerous tissue, which is limited by difficulties in getting real-time feedback on treatment progress and long treatment durations. The formation and activity of acoustic cavitation, specifically inertial cavitation, during HIFU exposures has been demonstrated to enhance heat...
