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

Assessment of fetal brain perfusion with contrast-enhanced ultrasound (CEUS) has not been performed in vivo in congenital diaphragmatic hernia (CDH). The development of the EXTra-uterine Environment for Neonatal Development allows investigation of CEUS and fetal brain perfusion parameters. The purpose of this study was to assess for aberrations in brain perfusion using CEUS in fetal lambs with CDH and correlate with cardiac output data. Read More

Timely intracranial imaging enables diagnosis, directs treatment, and provides prognostic information of infant malformation or injury. MRI is the gold standard for neuroimaging, but can be inhibited by transportation risk and incompatible support devices. Ultrasound (US) is portable, rapid, and inexpensive, but limited by lower sensitivity and specificity. Contrast-enhanced ultrasound (CEUS) improves diagnostic accuracy of US in other clinical applications. Our aim was to prospectively compare CEUS of the neonatal brain to MRI. Read More

Conventional Doppler US is known to have low sensitivity for the diagnosis of renal artery stenosis (RAS), in particular segmental renovascular disease. This study aims to determine if contrast-enhanced US (CEUS) can quantitatively provide assessment of renal arterial and parenchymal perfusion pre- and post- renal artery angioplasty in children and potentially be used as a follow-up imaging tool.

Imaging pediatric patients calls for modalities that are rapid and reduce or eliminate radiation exposure. As such, ultrasound is an exceedingly important modality in pediatric radiology. Ultrasound can be used for a large variety of indications and provides clinicians and radiologists with a real-time, point of care evaluation without radiation exposure. Grey scale and color Doppler ultrasonographic images do have some limitations including an inability to accurately define vasculature or detect/characterize lesions in solid organs. Fortunately, contrast enhanced ultrasound (CEUS) is now available for use in the United States. Ultrasound contrast agents are gas-filled microbubbles that are injected into the systemic vasculature that appear echogenic on grey scale ultrasound. Contrast enhanced ultrasound allows for more precise visualization of vasculature, determination of relative blood flow, and enhanced visualization of solid organs and lesions. The availability of CEUS provides pediatric radiologists with a powerful new tool for the evaluation of a variety of pathologies that traditionally required high radiation computed tomography or lengthy magnetic resonance imaging.
