We report the case of a 79-year-old patient who presented with a femoral iatrogenic pseudoaneurysm of delayed and unusual onset with immediately life-threatening massive bleeding. Ultrasound is the method of choice for the diagnosis of pseudo aneurysm. If there is not spontaneous closure, ultrasound-guided compression repair, minimally invasive percutaneous treatments, and surgical repair are t...

The use of therapeutic ultrasound within the Health Service is widespread and growing. The most common indication is to reduce inflammation. We have tested the influence of ultrasound on a model of acute inflammation in the rat, and we have found a complete absence of any anti-inflammatory action.

The feasibility and safety of magnetic resonance (MR) imaging-guided focused ultrasound surgery for uterine leiomyomas is reported. Sequential sonications were delivered to nine targets. Temperature-sensitive phase-difference MR imaging monitored the location of the focus and measured tissue temperature elevations, ensuring therapeutic dose. MR images and hysterectomy specimens were evaluated. ...

Endoscopic ultrasound (EUS) was first introduced into medical practice in 1980s as a diagnostic imaging modality for pancreatic pathology. EUS has the unique advantage of combining ultrasound and endoscopy to obtain detailed information of the gastrointestinal tract. Over the past decade, the use of EUS in liver diseases has been increasing. EUS, which was initially used as a diagnostic tool, i...

Contrast-enhanced ultrasound imaging is a radiation-free clinical diagnostic tool that uses biocompatible contrast agents to enhance signal, in order improve image clarity and performance. Ultrasound enhancing (UEA), which are usually gas microbubbles, administered intravenously either by bolus injection or continuous infusion. UEA increase the accuracy reliability of echocardiography, leading ...

A young male patient developed chronic, severe, and disabling right sided groin pain following resection of his left testicular cancer. Since there is considerable overlap, ultrasound guided, selective diagnostic nerve blocks were done for ilioinguinal, iliohypogastric, and genitofemoral nerves, to determine the involved nerve territory. It was revealed that genitofemoral neuralgia was the like...

The purpose of this study was to investigate the effect of therapeutic ultrasound upon some functional parameters in dogs with stifle joint osteoarthritis. Experimental osteoarthritis was induced in 6 mixedbreed dogs by injections of sodium monoiodoacetate in the left knee joint. The right joint served as control. The clinical and goniometric status of dogs was monitored at post injections days...

BACKGROUND Historically, military surgical doctrine has mandated exploratory laparotomy for all penetrating fragmentation wounds. We hypothesized that stable patients with abdominal fragmentation injuries whose computerized tomography (CT) scans for intraperitoneal or retroperitoneal penetration disclosed nothing abnormal, can be safely observed without therapeutic laparotomy. METHODS We retr...

The contrast enhanced imaging function of ultrasound contrast agents (UCAs) has been extensively investigated using physical acoustic signatures. It has a number of novel applications, including tissue‑specific molecular imaging and multi‑modal imaging. In addition there are numerous other therapeutic applications of UCAs, for example as vehicles for drug or gene delivery. These uses are discus...

Therapeutic ultrasound is widely employed in clinical applications but its mechanism of action remains unclear. Here we report prompt fluidization of a cell and dramatic acceleration of its remodeling dynamics when exposed to low intensity ultrasound. These physical changes are caused by very small strains (10-5) at ultrasonic frequencies (106 Hz), but are closely analogous to those caused by r...
