ceVUS is a radiation-free and sensitive examination to detect vesicoureteral reflux and image the urethra in children using ultrasound (US) and intravesical administration of an ultrasound contrast agent (UCA). Due to the growing interest to perform ceVUS in children, a urinary bladder phantom was developed to teach the technical aspects of the ceVUS examination. Here we describe the preparation and utility of this reusable phantom as a tool to simulate the UCA administration, distribution and the effect of different US parameters on the UCA appearance in the bladder.

Contrast enhanced voiding urosonography (ceVUS) is a radiation free, highly sensitive imaging modality for vesicoureteral reflux (VUR) detection and urethral imaging in children. CeVUS uses ultrasound (US) technology and an US contrast agent (UCA) that is instilled in the bladder via a catheter. This educational exhibit provides step-by-step instructions of our institutional protocol for performing ceVUS exams. Read More

<b>Contrast enhanced ultrasonography (CEUS) is a radiation free, highly sensitive imaging modality for pathology detection in children. CEUS uses ultrasound (US) technology in combination with US contrast agent (UCA). The UCA is administered intravenously via an IV catheter. The UCA is composed of gas-filled microbubbles. This educational exhibit has the aim to describe the procedure and imaging in CEUS from the sonographers’ perspective. </b> Read More

Assessment of fluid overload in hemodialysis patients is usually based on a patient’s ideal weight which presents a challenge, especially in children due to normal growth and development. Noninvasive, validated sonographic fluid balance measurements could potentially guide fluid removal in children undergoing hemodialysis. We examine changes in IVC diameter and lung b-lines in children pre- and post- dialysis. Read More

Contrast-enhanced ultrasound (CEUS) and shear wave elastography (SWE) have been widely studied in adult thyroid disease. However, evaluation of thyroid nodules using these tools in pediatric patients has yet to be published. We aim to evaluate the feasibility and safety of CEUS and SWE for thyroid nodules in children at the time of cytologic biopsy. Read More

Pediatric Contrast Enhanced Ultrasound (CEUS) is a safe and patient-friendly imaging modality. It improves the diagnostic capability of gray-scale and Doppler ultrasound without sedation, ionizing radiation and no use of iodinated or gadolinium-based contrast agents. Pediatric CEUS was originally used to detect vesicoureteral reflux, evaluate indeterminate focal liver lesions, assess and follow up solid-organ injuries sustained during blunt abdominal trauma. In 2016, the approval of Lumason® (Bracco Diagnostics Inc., Monroe Township, NJ) by the United States Food and Drug Administration (FDA) marked the beginning of a new era for CEUS imaging. Since then, clinical requests for pediatric CEUS not only increased in number but also for a variety of examinations covering practically every organ system, including pediatric brain, lungs, solid organs and bowel. In addition, intracavitary applications of pediatric CEUS are now extending beyond the urinary tract, to include urogenital and anorectal malformations. Intravenous and intracavitary CEUS is used in pediatric interventional radiology, to confirm enteric tube placement, guide biopsies and drainage procedures and aide organ vascular mapping (e.g. renal, central vessels). Novel pediatric CEUS applications now used include intranodal CEUS lymphangiography for confirmation of needle position preceding MRI lymphagiography. Pediatric CEUS is performed in a number of clinical settings including inpatient units, outpatient radiology, emergency department, and intraoperative. These evolving indications and uses of CEUS combined with continuous advances in ultrasound technology, such as three-dimensional/four-dimensional ultrasound and improved contrast sensitivity, are establishing pediatric CEUS as an important alternative imaging examination that can complement or supplement fluoroscopy, CT and MRI. This presentation reviews the current wide spectrum of pediatric CEUS applications and imaging findings, according to body part, and the associated imaging findings. Read More

Volume overload is linked to increased cardiovascular morbidity and mortality in children receiving hemodialysis (HD). Clinician assessment of volume status lacks accuracy and has substantial inter- and intra- observer variability. We investigated the use of ultrasound (US) skin thickness, and muscle elastography in pediatric HD patients. Read More
