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.

Fluoroscopic voiding cystourethrography (VCUG) and radionuclide cystography (RNC) are conventional techniques used for the diagnosis of vesicoureteral reflux (VUR) in children. Contrast-enhanced voiding urosonography (ceVUS) is a radiation-free alternative to the traditional VCUG. ceVUS has gained acceptance in Europe, but has not yet been widely adopted in the USA.

The purpose of this educational review is to describe our initial experience with ceVUS using the second generation US contrast agent Optison™, with a focus on optimization of examination technique, utility in the depiction of a variety of pathological entities, and a discussion of potential pitfalls.

Voiding cystourethrography (VCUG) has long been utilized in the diagnosis of vesicoureteral reflux in children with urinary tract infections. Sonographic techniques have been developed to make the same diagnosis without exposing the child to ionizing radiation. This presentation describes the implementation steps of a new service including: pharmacy approval and formulary addition; sonographer training and coordination with fluoroscopy technologists; referring clinician education and outreach. This exhibit educates the reader on how ceVUS can be performed, how it can be established at a children’s hospital, and the benefits it provides.

Correct technique and acquisition of images is shown using clinical case examples. Relevant anatomy is reviewed. Correlation of ultrasound abnormalities with VCUG results is provided. The process of training technologists and radiologists is highlighted. Pitfalls and tips to improve imaging are described. We will present results on how our new service has been accepted and utilized by the urologists and referring physicians. We have now performed over 50 ceVUS studies this year. Read More

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.

Evaluating the alignment and blood flow in the femoral head in patients with congenital hip dysplasia following reduction is essential to the treatment of dysplastic hips. Current practice involves an immediate postoperative contrast enhanced MRI of the casted child to identify hips that may be at risk for avascular necrosis. Contrast enhanced ultrasound (CEUS) is an emerging imaging modality that is feasible to evaluate the perfusion of the cartilaginous proximal femoral epiphysis intraoperatively, after hip reduction and prior to spica casting. This educational exhibit describes the procedure of intraoperative CEUS of the hip from the sonographers’ perspective. Read More
