Endoscopic ultrasound (EUS) provides high-resolution and real-time visualization of various layers the gastrointestinal (GI) tract beyond by combining technology with endoscopic [...]

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...

HYPOTHESIS High-resolution ultrasound and technetium Tc 99m sestamibi scanning can be used for preoperative localization of abnormal parathyroid glands in patients with hyperparathyroidism. DESIGN Ultrasound and sestamibi scanning were performed in patients undergoing neck exploration for hyperparathyroidism. If the 2 scans agreed in identifying a single adenoma, and surgery confirmed the loc...

We demonstrate that microscopic imaging is feasible in ultrasound-modulated optical tomography (UOT) of soft biological tissues, using a high-frequency focused ultrasound transducer with a 75-MHz central frequency. Our experiments in tissue mimicking phantoms show that at an imaging depth of about 2 mm, an axial resolution better than 30 microm can be achieved, whereas the lateral resolution is...

INTRODUCTION In this study we aimed to determine whether high-resolution ultrasound (US) can identify the iliohypogastric (IH), ilioinguinal (II), and genitofemoral (GF) nerves and their relations. METHODS This investigation, initially undertaken in cadavers, was followed by a high-resolution US study in 30 healthy adult volunteers (180 nerves) by 2 musculoskeletal radiologists on separate oc...

The purpose is to evaluate the feasibility of imaging mouse brain with high resolution ultrasound (HiRes US), and generation of mouse brain tumor (glioma) model under HiRes US guided implantation of glioma cells. Normal mouse brain was imaged with 30 MHz HiRes US in six pups and ten adult nude mice. Glioma model was developed by injecting human glioma cells (5 × 10), U-87MG-luc, under HiRes US ...

This update examines recent articles and evidence for the role of ultrasound in the diagnosis and management of shoulder impingement syndromes and emphasizes its principal application in evaluation for external impingement. Shoulder ultrasound is commonly used as the initial investigation for patients with shoulder pain and suspected impingement. This is due to the high resolution of current ul...

Despite the technical advances in radiological imaging modalities that have occurred in recent years in detecting foreign bodies like wood and plastics, they are not very often relied upon. Five of the six cases reported below seen over a period of 6 months, had a delayed presentation and ultrasound was found to be very useful in detecting and planning the treatment. The author strongly recomme...

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...

Introduction: One of the most obvious morphological changes due to aging is the formation of facial wrinkles, which are remarkably visible at middle ages and can have a significant effect on the quality of life of individuals. It is believed that UVB is one of the main causes of aging by stimulating reactive oxygen species. Nanoemulsion was loaded with fullerene, a strong free ...
