This study investigates the influence of blood flow on temperature distribution during high-intensity focused ultrasound (HIFU) ablation of liver tumors. A three-dimensional acoustic-thermal-hydrodynamic coupling model is developed to compute the temperature field in the hepatic cancerous region. The model is based on the nonlinear Westervelt equation, bioheat equations for the perfused tissue ...

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 ...

BACKGROUND High-intensity focused ultrasound (HIFU) allows to inflict intracorporal thermal lesions without penetrating the skin or damaging the surrounding tissue. This analysis intends to assess the magnitude of HIFU-induced ablations within benign thyroid nodules using scintigraphic imaging with (99m)Tc. METHODS Ten cold, hot, or indifferent nodules were treated using multiple pulses of HI...

The minimally invasive high-intensity focused ultrasound (HIFU) therapy is thermal ablation treatment for late-stage pancreatic carcinoma with widely recognized safety and effectiveness, but there are currently no instant assessment methods for its ablation effect. It is vital to find a real-time high-sensitive assessment method. This research aims to dynamically observe the variation rules of ...

The aim of this study was to retrospectively evaluate the safety and feasibility of high-intensity focused ultrasound (HIFU) treatment combined with suction curettage under hysteroscopic guidance for cesarean scar pregnancy (CSP).Fifty-three patients with definite CSP were treated with HIFU followed by suction curettage under hysteroscopic guidance. All the patients received 1 session of HIFU a...

The aim of the present study was to evaluate the safety and efficiency of an intravenously delivered nano-hydroxyapatite (Nano-HA) solution into a rabbit model (Oryctolagus cuniculus) to determine the potential enhancement of high-intensity focused ultrasound (HIFU) for the ablation of hepatocellular carcinoma (HCC) in liver tissue. The present study clearly indicated that the intravenous deliv...

OBJECTIVE To evaluate the biochemical disease-free survival (DFS), predictors of clinical outcome and morbidity of patients with localized prostate cancer treated with high-intensity focused ultrasound (HIFU), a noninvasive treatment that induces complete coagulative necrosis of a tumour at depth through the intact skin. PATIENTS AND METHODS In all, 63 patients with stage T1c-2bN0M0 localized...
