Pediatric chronic liver disease (CLD) poses a significant clinical challenge, necessitating precise diagnostic tools for comprehensive evaluation. Microvascular perfusion abnormalities play a pivotal role in disease progression. Contrast-enhanced ultrasound (CEUS) detects the flow in the micro-vessels, however, objective means are needed for better understanding. In this study we evaluate a novel quantitative method utilizing CEUS for assessing microvascular perfusion in pediatric patients with CLD. Read More

The rapid growth of contrast-enhanced ultrasound research and applications presents the need for cooresponding educational tools and training methods. Hands-on education is an ideal mechanism for learning image techniques, sparking active engagement and curiosity to learn more. Custom pediatric phantoms for ceVUS allow for specific education goals in an engaging and translatable fashion and allow the learner to practice the technique prior to engaging in patient care.

Ultrasound is the first-line screening tool for numerous pediatric pathologies. Its advantages include lack of ionizing radiation, non-invasiveness, real-time dynamic evaluation, and flow assessment capabilities. While conventional Doppler is used for macrovascular evaluation in conditions such as ischemia, infections, and neoplasms, ultrasound microbubble contrast agents allow for more precise perfusion quantification. Microvascular flow imaging (MVI) is a novel technique that employs advanced algorithms for clutter and noise suppression, enabling superior visualization of small vessels and slow-velocity flow without contrast. This technique may reduce the need for contrast-enhanced follow-up studies, except when arterial and venous wash-in and wash-out characteristics are crucial for diagnosis. The utility of MVI in pediatric conditions needs further exploration as this technology is part of ultrasound clinical systems. Read More
