Background: Medical diagnostic ultrasound has been used by various specialties since the 1950s. Contemporary point of care ultrasound (POCUS) was first researched and utilized by emergency physicians in the mid 1980s. Emergency physicians have formally defined and pioneered POCUS over the past two decades. Research in a broad array of applications indicate improved patient care via procedural s...

Ultrasound is a popular imaging modality for its safety and low cost. Its role in the diagnosis of breast cancer is discussed, and its performance is then compared those of mammography (gold standard) and MRI. Besides conventional B-mode and color or power Doppler ultrasound images, latest development of acoustic radiation force impulse (ARFI) and supersonic shear imaging and their application ...

The combination of microbubbles and ultrasound has emerged as a promising method for local drug delivery. Microbubbles can be locally activated by a targeted ultrasound beam, which can result in several bio-effects. For drug delivery, microbubble-assisted ultrasound is used to increase vascular- and plasma membrane permeability for facilitating drug extravasation and the cellular uptake of drug...

The brain is protected from the entry of foreign substances by blood-brain barrier (BBB), but becomes a barrier while chemotherapy is needed for the brain diseases. Ultrasound with microbubbles (MBs) has been shown to noninvasively increase the permeability of the BBB in the normal tissue and brain tumor. The real mechanism for disruption is still unknown. Hemorrhage was usually found in the so...

PURPOSE OF REVIEW The aim of this review is to provide the theoretical and practical knowledge essential for non-radiologists to develop the skills necessary to apply thoracic ultrasound as an extension of clinical assessment and intervention. RECENT FINDINGS Issues relating to training and competence are discussed and a library of thoracic ultrasound videos is provided to illustrate artefact...

It has been that suggested the use of two dimensional (2D) ultrasound to facilitate placement of central venous cannulae in the internal jugular vein improves patient safety and reduces complications. Since the introduction of the National Institute for Clinical Excellence Technology Appraisal Guideline Number 49 in 2002, promoting the use of ultrasound in placement of internal jugular venous c...

PURPOSE We evaluate the feasibility and potential advantages of ProACT system implantation using transrectal ultrasound rather than fluoroscopy for guidance. MATERIALS AND METHODS The transrectal ultrasound guided procedure was done between June and October 2005 in 7 patients with a mean age of 68.4 years (range 53 to 76) with mild to severe stress urinary incontinence after laparoscopic tran...

Multi-modality fusion imaging for targeted prostate biopsy is difficult because of prostate motion during the biopsy procedure. A closed-loop control mechanism is proposed to improve the efficacy and safety of the biopsy procedure, which uses real-time ultrasound and spatial tracking as feedback to adjust the registration between a preoperative 3D image (e.g. MRI) and real-time ultrasound image...

Pancreatic carcinoma (PC) is an aggressive disease that represents the fifth cancer-related cause of death in Spain. Surgery is the only potentially curative treatment, but in about 80% of patients the tumor is unresectable at diagnosis. Due to its accessibility, safety and profitability, abdominal ultrasound is usually the first imaging technique to be performed when a PC is suspected. The mai...
