Acute right upper quadrant (RUQ) pain is a common presenting symptom in emergency departments and outpatient medical practices, and is most commonly attributable to biliary and hepatic pathology. Ultrasound should be used as a first-line imaging modality for the diagnosis of gallstones and cholecystitis, as it allows the differentiation of medical and surgical causes of upper abdominal pathology, and in many circumstances is sufficient to guide patient management. Knowledge of strengths and limitations of ultrasound in the evaluation of RUQ is paramount in correct diagnosis. A spectrum of RUQ pathology for which a RUQ ultrasound examination should reasonably be considered as the initial imaging modality of choice will be reviewed.

Randomized Controlled Trial
Ultrasound-Guided Fine-Needle Aspiration in the Neck Region Using an Optical See-Through Head-Mounted Display: A Randomized Controlled Trial.
The purpose of this study was to examine the feasibility of an optical see-through head-mounted display (OST-HMD) to improve ergonomics during ultrasound-guided fine-needle aspiration (FNA) in the neck region. ⋯ The OST-HMD improved the practitioners' ergonomics and can be adopted for performing ultrasound-guided interventional procedures in clinical settings.

Establishing a definitive airway is often the first step in emergency department treatment of critically ill patients. Currently, there is no agreed upon consensus as to the most efficacious method of airway confirmation. Our objective was to determine the diagnostic accuracy of real-time sonography performed by resident physicians to confirm placement of the endotracheal tube during emergent intubation. ⋯ A simple transverse tracheal sonographic examination performed by emergency medicine resident physicians can be used as an adjunct to help confirm correct endotracheal tube placement during intubation. In our cohort, the level of training did not appear to affect the ability of residents to correctly identify the endotracheal tube position.

To compare the agreement and interobserver variability of diagnostic handheld ultrasound (US) and a single volume on an automated breast volume scanner (ABVS) and to determine whether there was a significant difference if the ABVS was used by a sonographer or mammographic technologist. ⋯ Performing a single-view diagnostic ABVS examination has good agreement with a handheld diagnostic US workup. There is no difference if the ABVS is used by a sonographer or mammographic technologist.
