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...

The American Medical Society for Sports Medicine (AMSSM) developed a musculoskeletal ultrasound curriculum for sports medicine fellowships in 2010. As the use of diagnostic and interventional ultrasound in sports medicine has evolved, it became clear that the curriculum needed to be updated. Furthermore, the name 'musculoskeletal ultrasound' was changed to 'sports ultrasound' (SPORTS US) to ref...

-This study demonstrated techniques for visualization of detailed brain anatomy with two dimensional ultrasound. The use of large aperture focused ultrasound transceivers appears to be essential for displaying the outlines of thalamus, internal capsule and substantial nigra in addition to those of the ventricles. The ability to vary grey scale and edge enhancement using either linear or logarit...

Since the introduction of medical ultrasound in the 1950s, modern diagnostic ultrasound has progressed to see many major diagnostic tools come into widespread clinical use, such as B-mode imaging, color-flow imaging, and spectral Doppler. New applications, such as panoramic imaging, three-dimensional imaging, and quantitative imaging, are now beginning to be offered on some commercial ultrasoun...

Ultrasound-induced blood stasis has been observed for more than 30 years. Most of the literature has been focused on the health risks associated with this phenomenon and methods employed to prevent stasis from occurring during ultrasound imaging. To date, experimental observations have been either in vitro or invasive. The current work demonstrates ultrasound-induced blood stasis in murine norm...

INTRODUCTION The purpose of this study was to develop an evidence-based guideline for the use of neuromuscular ultrasound in the diagnosis of carpal tunnel syndrome (CTS). METHODS Two questions were asked: (1) What is the accuracy of median nerve cross-sectional area enlargement as measured with ultrasound for the diagnosis of CTS? (2) What added value, if any, does neuromuscular ultrasound p...

Introduction: Transabdominal and transvaginal ultrasound can be used in distinguishing lesions of adnexa. Transvaginal has higher diagnostic accuracy than transabdominal when compared with gold standard histopathology. It also provides better resolution as to ultrasound.
 Aims: To find the efficacy sonographic techniques adnexal pathologies by comparing against biopsy.
 Methods: Hospi...

Pleural effusion (PE) is common among ICU and acutely ill patients. Traditionally plain chest radiography (CXR) has been done for pleural effusion evaluation in ICU. However, better results have been reported by ultrasound for the diagnosis of this condition in ICU. In this study, we compared two methods of ultrasound and CXR in PE detection in ICU patients. Also we studied the percentage of t...
