Background/introduction Breast fibroadenomata (FAD) are the most common breast lesions in woman. For palpable lesions, three options are available: reassurance (with or without follow-up), vacuum assisted mammotome (VAM) or surgical excision. High intensity focused ultrasound (HIFU) is a non-invasive ablative technique in which an ultrasound (US) beam propagates through tissue as a high-frequen...

Nanoemulsion is an alternative and promising approach to overcome insolubility and bioavailability problems of bioactive compounds. In this study, the sonication parameter for preparing nanoemulsions with high α- tocopherol and linolenic acid content were optimized by using response surface methodology and their stability were evaluated during 2 months’ storage. The response surface analysis re...

Low intensity pulsed ultrasound is used in the clinical treatment of fractures and other osseous defects. Level I clinical studies demonstrate the ability of a specific ultrasound signal (1.5 MHz ultrasound pulsed at 1 kHz, 20% duty cycle, 30 mW/cm(2) intensity (SATA)) to accelerate the healing time in fresh tibia, radius and scaphoid fractures by up to 40%. Additionally, the same ultrasound si...

Introduction: Low-intensity doses of ultrasound are currently used in the treatment of various musculoskeletal conditions. However, this ultrasonic therapy may be contraindicated in children due to the potential for growth disturbances, particularly at the epiphyseal plates of the long bones. We hypothesize that current clinical therapeutic doses of ultrasound (0.5 W/cm2) will not cause prematu...

Background/introduction Fibroadenomas are common, benign lesions of the breast. A minority of fibroadenomas will disappear without treatment, but most increase in size or remain unchanged. Current management of patients with fibroadenomas in the United States varies on a case by case basis and includes observation or surgical excision. Many patients find their fibroadenoma bothersome, and opt f...

BACKGROUND The effect of low-intensity ultrasonography on fracture healing is controversial, and current management of fractures does not generally involve the use of ultrasound therapy. We describe a systematic review and meta-analysis of randomized controlled trials of low-intensity pulsed ultrasound therapy for healing of fractures. METHODS We searched 5 electronic databases (MEDLINE, EMBA...

Tissue destruction by thermal ablation occurs when the targeted delivery of heat or cold causes a rapid change in temperature (>55°C for heat or <−20–50°C for cold) in the local tissue environment. Imaging can be used to localize and target the thermal effects to the target/tumor for treatment, control the energy deposition, and assess treatment response. Therapeutic applications of ultrasound ...

Introduction: Mechanical index (MI) is used for quantifying acoustic cavitation and the relationship between acoustic pressure and the frequency. In this study, modeling of the MI was applied to provide treatment protocol and to understand the effective physical processes on reproducibility and gene expression of fibroblast cells. Skin damage can occur of burn, cuts, abrasions ...

In therapeutic ultrasound applications, accurate ultrasound output intensities are crucial because the physiological effects of therapeutic ultrasound are very sensitive to the intensity and duration of these applications. Although radiation force balance is a benchmark technique for measuring ultrasound intensity and power, it is costly, difficult to operate, and compromised by noise vibration...
