OBJECTIVES: To compare the diagnostic performance for advanced hepatic fibrosis measured by 2D shear-wave elastography (SWE), using either the coefficient of variance (CV) or the interquartile range divided by the median value (IQR/M) as quality criteria. METHODS: In this retrospective study, from January 2011 to December 2013, 96 patients, who underwent both liver stiffness measurement by 2D SWE and liver biopsy for hepatic fibrosis grading, were enrolled. The diagnostic performances of the CV and the IQR/M were analyzed using receiver operating characteristic curves with areas under the curves (AUCs) and were compared by Fisher's Z test, based on matching the cutoff points in an interactive dot diagram...

Opening a chest in an experimental echocardiographic animal study eliminates ultrasound signal attenuation by the chest wall. We developed a scanning technique that involves the use of an attenuative pad created from a mixture of urethane and titanium dioxide. The pad was interposed within transmission gel between the transducer face and cardiac surface in open-chest scans in a porcine model. Comparative measurements of left ventricular echogenicity without and with the pad demonstrate that the pad reproducibly causes ultrasound signal attenuation that closely mimics chest attenuation in clinical transthoracic echocardiographic studies...

OBJECTIVES: Objective measures are needed to guide the novice's pathway to expertise. Within and outside medicine, eye tracking has been used for both training and assessment. We designed this study to test the hypothesis that eye tracking may differentiate novices from experts in static image interpretation for ultrasound (US)-guided regional anesthesia. METHODS: We recruited novice anesthesiology residents and regional anesthesiology experts. Participants wore eye-tracking glasses, were shown 5 sonograms of US-guided regional anesthesia, and were asked a series of anatomy-based questions related to each image while their eye movements were recorded...

Pericardiocentesis is a rare life-saving procedure for patients with cardiac tamponade. Due to the infrequency of this procedure, simulation models are often used for training. Commercial models are generally expensive. Proposed homemade models offer a lower-cost alternative but can be labor and time intensive. The purpose of this study was to determine the feasibility of a limited use, low-cost ultrasound-guided pericardiocentesis model as a training tool for emergency physicians. Our model proved to be a practical, easily implemented, and acceptable model for training emergency physicians, including residents and students, in ultrasound-guided pericardiocentesis...

REVIEW
Usman Tarique, Brandon Tang, Manni Singh, Kulamakan Mahan Kulasegaram, Jonathan Ailon
The clinical applications of point-of-care ultrasound (US) have expanded rapidly over the past decade. To promote early exposure to point-of-care US, there is widespread support for the integration of US curricula within undergraduate medical education. However, despite growing evidence and enthusiasm for point-of-care US education in undergraduate medical education, the curricular design and delivery across undergraduate medical education programs remain variable without widely adopted national standards and guidelines...

Modesto J Varas Lorenzo, Ramón Abad Belando, Elena Sánchez-Vizcaíno Mengual
Conventional endoscopic sonography has allowed precise diagnostics without disturbances, and miniprobes can be easily introduced through the biopsy channel of the endoscope. Miniprobe endoscopic sonography has many benefits compared with conventional endoscopic sonography. Although there are well-known indications for miniprobe endoscopic sonography in endoscopic digestive tract assessment, there is still a need for this method to be widely spread among physicians and commonly used by most endoscopists. The aim of this series was to describe a multicenter retrospective experience with 1451 procedures using miniprobes, presenting examples and the applicability and usefulness of this technology in the daily activities of an endoscopy department...

OBJECTIVES: Although power Doppler imaging has been used to quantify tissue and organ vascularity, many studies showed that limitations in defining adequate ultrasound machine settings and attenuation make such measurements complex to be achieved. However, most of these studies were conducted by using the output of proprietary software, such as Virtual Organ computer-aided analysis (GE Healthcare, Kretz, Zipf, Austria); therefore, many conclusions may not be generalizable because of unknown settings and parameters used by the software...
