Gastric emptying study was performed following demonstration of gastroesophageal reflux in a child with persistent vomiting. The dynamic study was performed with liquid formula labeled with Tc-99m sulfur colloid. Images are shown at 30 minutes and 60 minutes and clearly demonstrate all of the small bowel to the right of midline. Subsequent upper GI barium study confirmed the diagnosis of malrotation. The upper GI series remains the "gold standard" for the diagnosis of malrotation, but this diagnosis can be suggested from other studies including ultrasound and, more rarely, as described in this case, gastric emptying studies.
