Increased Activity in the Lung Field on Gastroesophageal Scintigraphy Is Not Always Due to Aspiration
Elevated activity in the lung field on gastroesophageal scintigraphy (milk scan) generally indicates aspiration of the gastric content that has refluxed to the pharynx. An 18-year-old man underwent to gastroesophageal scintigraphy to assess the rate of gastric emptying. Increased activity was noted in the left lower lung field during the image acquisition. Careful analysis of the images showed that this activity was caused by hiatal herniation.
