Volumetric high-intensity focused ultrasound (HIFU) guided by multiplane magnetic resonance (MR) thermometry has been shown to be a safe and efficient method to thermally ablate large tissue volumes. However, the induced temperature rise and thermal lesions show significant variability, depending on exposure parameters, such as power and timing, as well as(More)
OBJECTIVE The purpose of this prospective multicenter study was to assess the safety and technical feasibility of volumetric Magnetic Resonance-guided High Intensity Focused Ultrasound (MR-HIFU) ablation for treatment of patients with symptomatic uterine fibroids. METHODS Thirty-three patients with 36 fibroids were treated with volumetric MR-HIFU(More)
Focused ultrasound is currently being developed as a non-invasive thermal ablation technique for benign and cancerous tumors in several organ systems. Although these therapies are designed to ablate tissue purely by thermal means, cavitation, the formation and collapse of gas bubbles, can occur. These bubbles can be unpredictable in their timing and(More)
Over the past decade, numerous minimally invasive thermal procedures have been investigated to treat benign prostate hyperplasia and prostate cancer. These hyperthermia and thermal surgery techniques have employed RF energy, microwave radiation, laser, and acoustic energy to heat and necrose a localized region of tissue. Of these methods, ultrasound has(More)
