Pediatric gastrointestinal imaging.

The traditional areas of interest in pediatric gastrointestinal radiology (gastroesophageal reflux, malrotation, necrotizing enterocolitis) were the source of many new and important studies in the past year. Information gleaned from correlative nonradiologic studies or from newer modalities provided the new focus of interest. The imaging and treatment of intussusception remains a topic in which literature is evolving. Pneumatic reduction is repeatedly being shown to be safe and effective. There have been a large number of studies addressing polysplenia, biliary atresia, and liver transplantation. Images of the anomalies associated with polysplenia were published in several sources. One paper reported better than previously described results of liver transplantation in the subset of patients with polysplenia and biliary atresia.
