Gastroesophageal reflux scintigraphy can be performed with acidified orange juice labeled with technetium-99m sulfur colloid. Compared with fluoroscopy, this allows for a longer time of evaluation, a decreased radiation dose, and the ability to semiquantitate the amount of reflux. However, gastroesophageal reflux scintigraphy has little role in the adult patient due to limited sensitivity and the availability of other methods of evaluation.
