Esophageal transit scintigraphy (ETS) complements anatomic imaging studies such as contrast esophagography for the evaluation of esophageal motility disorders. This noninvasive technique provides reliable and reproducible functional data that is useful in the evaluation of both primary and secondary esophageal motility disorders. This image-rich exhibit will provide an overview of this examination using representative examples of ETS studies in children, including technical considerations, imaging features in various disorders, and pitfalls in intepretation, with correlative fluoroscopic and/or CT images.

A three year old child was referred to the Nuclear Medicine Department for bone scintigraphy for staging. This patient was diagnosed with hepatoblastoma. Imaging findings showed no bony disease, however, radiotracer uptake was demonstrated throughout the liver. Read More

Brain death, also known as death by neurologic criteria, (BD/DNC) is the permanent loss of total brain function in individuals who have sustained catastrophic brain injuries. Accounting for approximately 5% of pediatric deaths, BD/DNC remains a clinical diagnosis, which is often emotionally laden and not always straightforward. When results are equivocal or there exist limitations to the safe completion of the clinical assessment, clinicians rely on ancillary testing to make informed decisions. In October 2023, updated adult and pediatric BD/DNC consensus guidelines were published which reinforce differences in the recommendations for testing between the adult and pediatric populations. It is, therefore, crucial for Pediatric Radiologists to understand these guidelines and the critical role radiology plays in supporting this important diagnosis.
In this educational exhibit, we will review the recent consensus guidelines and clinical indications for the use of imaging in BD/DNC evaluation. We will provide a step-by-step guide which will include patient preparation, radionuclide or contrast administration, image acquisition, and image interpretation for the two validated methods of pediatric BD/DNC ancillary testing: Radionuclide Perfusion Scintigraphy and 4-Vessel Catheter Angiography.
Although 4 vessel catheter angiography is considered the gold standard in ancillary BD/DNC testing, as it is believed to be both 100% sensitive and 100% specific, radionuclide scintigraphy is the more widely used modality in the pediatric population, owing to the less invasive nature of the exam. Neither exam is without challenges related to limited availability and technical skill required yet are currently the only validated radiologic tools recommended for use in brain death diagnosis. Our exhibit will review multiple cases of evaluation for BD/DNC, accentuating imaging findings and pearls/pitfalls of acquisition and interpretation. Opportunities for investigation of other available imaging techniques will also be highlighted. Read More
