Endoscopic ultrasound has become an essential tool in modern gastroenterology and abdominal surgery. Compared with all other endoscopic methods, it has the most potential for innovation and its future looks bright. Thus, we compiled this summary of established and novel applications of endoscopic ultrasound methods to inform the reader about what is already possible and where future development...

BACKGROUND Catheter-based therapeutic ultrasound thrombolysis was recently shown to be effective and safe. The purpose of this work was to study the safety and efficacy of external high-intensity focused ultrasound thrombolysis guided by ultrasound imaging in experimental settings. METHODS AND RESULTS A therapeutic transducer was constructed from an acoustic lens and integrated with an ultras...

The design of endoscopic ultrasound (EUS) instruments has been improved to provide a wide therapeutic channel and an elevator to facilitate the movement of needles and medical devices. These im− provements make it possible to carry out combined ultrasound and endoscopic ap− proaches in the pancreas and duodenal papilla, with ultrasound examination of surrounding fluid collections [1± 5]. Cys− t...

In this clinical study, we have compared routine diagnostic dose (131)I scan and (99m)TcO4(-) thyroid scintigraphy with therapeutic dose (131)I imaging for accurate thyroid remnant estimation after total thyroidectomy. We conducted a retrospective review of the patients undergoing total thyroidectomy for differentiated thyroid carcinoma (DTC) and subsequently receiving radioactive iodine (RAI) ...

A specific increase in temperature is necessary to achieve a temperature-mediated therapeutic impact by ultrasound in rehabilitation. In order to obtain a physical basis for a definite temperature rise at a certain depths in the human body a human cadaver study in situ was conducted. A set of 16 experiments was carried out with an ultrasound frequency of 1 and 3 MHz. For each frequency the puls...

Background:   Patellofemoral pain syndrome (PFPS) is defined as pain surrounding the patella when sitting with bent knees for prolonged periods of time or when performing activities like ascending or descending stairs, squatting or   athletic activities. Patella dislocation is not included in PFPS.     Purpose:   This review analyzes the evidence based conservative management of PFPS.   Methods...

BACKGROUND AND PURPOSE A recent novel application of ultrasound therapy is the treatment of bone fractures. The aim of this study was to investigate the effect on fracture repair of ultrasound produced by a conventional therapeutic ultrasound unit as used by physical therapists. SUBJECTS AND METHODS Bilateral midshaft femur fractures were created in 30 adult male Long-Evans rats. Ultrasound t...

The effects of acoustic waves on membrane structures, and any resulting consequences of this treatment on membrane subunit structures, remain poorly understood, as are the principals of related clinical effects. With a focus on morphological changes in the nuclear envelope, the current study presents detailed observations of membrane structures exposed to therapeutic ultrasound. Ultrasound trea...

Medical applications of ultrasound were first investigated about seventy years ago. It has rapidly evolved since then, becoming an essential tool in medical imaging. Ultrasound ability to provide real time images with frame rates exceeding several hundred frames per second allows one to view rapid anatomical changes as well as to guide minimal invasive procedures. By, combining Doppler techniqu...
