The literature concerning the efficacy and safety of transrectal high-intensity focused ultrasound (HIFU) for the treatment of localized prostate cancer still comprises a relatively small number of articles. The main studies have been published by four teams using an apparatus available in Europe for several years. The recently presented results of the European Multicentre Study and the study b...

BACKGROUND To assess the long term efficacy and tolerability of one or two ultrasound (US)-guided high-intensity focused ultrasound (HIFU) treatment in patients with breast fibroadenoma (FA). METHODS Twenty patients with 26 FA were selected for US-guided HIFU. The therapy was performed in one or two sessions. FA volume was assessed before and followed up to 24 months after the last HIFU. Afte...

In this study, the effects of high-intensity-focused ultrasound (HIFU) treatment on benign uterine tumor patients were examined. A total of 333 patients diagnosed with fibroids or adenomyosis using diagnostic sonography, treated with HIFU between February 4, 2010 and December 29, 2014 at a hospital in Korea, and followed up for three or six months were selected for this study. Their benign uter...

Purpose. To evaluate postoperative morbidity and long term oncologic and functional outcomes of high intensity focused ultrasound (HIFU) compared to brachytherapy for the treatment of localized prostate cancer. Material and Methods. Patients treated by brachytherapy were matched 1 : 1 with patients who underwent HIFU. Differences in postoperative complications across the two groups were assesse...

PURPOSE We present the preliminary results of patients with advanced stage renal malignancy treated with high intensity focused ultrasound (HIFU), and investigate the safety and feasibility of using HIFU in the treatment of selected patients with renal tumors. MATERIALS AND METHODS HIFU treatment was performed in 12 patients with advanced stage renal cell carcinoma and 1 patient with colon ca...

BACKGROUND Radiotherapy is a critical component of the multidisciplinary management of cancers of the head and neck. It may comprise the primary curative treatment modality or is used in an adjuvant setting to improve local control and survival by preventing seeding and reseeding of distant metastases from persistent reservoirs of locoregional disease. Although considerable advances have been m...

BACKGROUND High-intensity focused ultrasound (HIFU) treatment has recently emerged in response to the increasing demand for noninvasive procedures for skin lifting and tightening. OBJECTIVE This study was aimed at evaluating the clinical efficacy of and patient satisfaction with HIFU treatment for wrinkles and laxity in seven different areas of the face in Asian skin. METHODS Twenty Korean ...

Understanding the effect of overlaying tissues on HIFU lesion is crucial for estimating HIFU dose distribution at a target tissue. We have run a series of experiments to systematically observe the effects of the overlaying tissues on the HIFU beam and ultimately the lesion created in the target tissue. First, we mapped out the HIFU transducer beam (in low power) under water without and with dif...

Materials and methods A movable circle surface coils with a low input impedance preamplifier were made to connect the receive system of a 1.5T MRI scanner (Symphony, Siemens). The coil was moved together with the HIFU transducer during the HIFU ablation. The dynamic temperature images during HIFU ablation of porcine meat and living mini-pig leg were measured by this home-made coil. MR temperatu...

Objective Fetal endoscopic tracheal occlusion (FETO) has been reported to be beneficial to patients with congenital diaphragmatic hernia (CDH). It needs highly invasive procedures for balloon removal (fetoscopic and/or ultrasound-guided), and carries a given risk for both mother and fetus. We have reported the potential usefulness of high-intensity focused ultrasound (HIFU) as a noninvasive ext...
