Purpose or Case Report: The American College of Radiology Pediatric LI-RADS Working Group was formed in 2017 with the task of advancing the imaging work up, diagnosis, and management of pediatric liver tumors, particularly pediatric hepatic malignancies. This exhibit will present how the Pediatric LI-RADS Working Group is working towards this goal by means of advocacy, education, and research. In regard to advocacy, the Working Group is a strong proponent for the standardization of imaging practice for pediatric liver tumors. Based on expert interpretation of the literature, the Working Group established consensus imaging recommendations for children with a known or suspected liver neoplasm. This exhibit will highlight the key recommendations for choosing imaging modality and protocol for the work up of a pediatric liver tumor. Education is another major component of the Working Group’s mission. The group has presented at meetings and published manuscripts on various topics. Topics include age and indication-based imaging strategies for pediatric liver tumors and liver masses in children with predisposition syndromes. This exhibit will touch on the major teaching points of these papers. Lastly, this exhibit will present the research conducted by the Pediatric LI-RADS Working Group. Their research studied the utility of applying adult LI-RADS criteria to children. Another study analyzed the imaging features of hepatocellular carcinoma in children with and without an underlying predisposition. To summarize, through discussion of the major accomplishments of the Pediatric LI-RADS Working Group, this exhibit will provide insight, education, and resources for the radiologist interpreting pediatric liver tumors.
