Focused ultrasound (FUS) has been employed on a wide range of clinical applications to safely and non-invasively achieve desired effects that have previously required invasive and lengthy procedures with conventional methods. Conventional electrical neuromodulation therapies that are applied to the peripheral nervous system (PNS) are invasive and/or non-specific. Recently, focused ultrasound ha...

BACKGROUND Conventional transabdominal ultrasound usually fails to visualize parts of the ureter or extrahepatic bile duct covered by bowel gas. In this study, we propose a new method for gaining acoustic access to the ureters and extrahepatic bile duct to help determine the nature of obstruction to these structures when conventional transabdominal ultrasound fails. METHODS The normal saline ...

Medical ultrasound imaging is a technique that has become much more prevalent than other medical imaging techniques since it is more accessible, less expensive, safe, simpler to use and produces images in the real time. However, images produced by an ultrasound imaging system, must be of sufficient quality to provide accurate clinical interpretation. The most commonly used image quality measure...

Lung cancer remains one of the most common malignant tumors. Identifying cervical lymph node metastases is important to stage lung cancer, evaluate patients’ prognosis and select appropriate treatments. This study evaluated utility conventional ultrasound combined with contrast-enhanced (CEUS) quantitative analysis in diagnosing nodes neck. The 39 patients primary who underwent CEUS ultrasound-...

We present a case of urinary tuberculosis investigated initially by ultrasound and multidetector computed tomography (MDCT). The MDCT-derived volumetric data were used to generate virtual cystoscopy (VC) images, which revealed a bladder ulcer. The presence of this ulcer was confirmed by conventional cystoscopy-guided biopsy and there was good agreement regarding various features of the ulcer, s...

BACKGROUND AND PURPOSE Real-time compound ultrasound imaging is a new technique for improving the image quality of B-mode scanning. We investigated the value of this method for the characterization of atherosclerotic plaques in the internal carotid artery. METHODS Thirty-two patients (22 men, 10 women; mean age, 75 years) with plaques of the internal carotid artery as identified by high-resol...

Abstract Ultrasound-assisted chalcopyrite leaching has been reported previously, showing a noticeable improvement in kinetics. However, the effect of ultrasound on oxidation kinetics from an electrochemical perspective not addressed. This study examines ultrasonic enhancement sulfuric acid solution both conventional and electrochemistry aspects. Electrochemical techniques, including linear swee...

Objective To evaluate the diagnostic accuracy of elastography for breast cancer identification in patients with indeterminate lesions on ultrasound. Methods This prospective, descriptive study included patients with indeterminate breast lesions in the ultrasound and with indication for percutaneous or surgical biopsy. The elastography was evaluated by qualitative analysis and by two methods for...

BACKGROUND Prompt recognition and treatment of a tension pneumothorax is critical to reducing mortality in both military and civilian settings. Physician assistants, Special Operations Forces (SOF) and conventional force Medics are often the first medical providers to care for combat trauma patients with penetrating chest trauma and frequently have limited diagnostic capabilities available to t...
