Study Notes
Gastroesophageal Reflux Complications
- Esophagitis and dysphagia (difficulty swallowing) in adults.
- Failure to thrive and aspiration pneumonia in infants.
Diagnostic Method: Gastroesophageal Scintigraphy
- Sensitive method for detecting reflux.
Patient Preparation
- Fast for several hours before imaging.
- Adults: 150 mL 99Tc-sulfur colloid mixed with orange juice and 150 mL dilute hydrochloric acid orally.
- Infants: Mixed with infant formula via a nasogastric tube or baby bottle.
- Entire tracer volume must be consumed.
Imaging
- Patient Positioning: Supine position under the scintillation camera with the stomach positioned low to include the esophagus and lung fields.
- Image Acquisition: Serial images obtained with varying abdominal pressure using an abdominal binder.
- Delayed Imaging: Delayed lung field images up to 24 hours after tracer administration to detect intermittent reflux.
Image Findings
- Esophageal Reflux Confirmation: Presence of radioactivity in the esophagus or lungs.
- Normal Study Result: No esophageal reflux observed.
Technical Considerations
- Patient Side Effect: The patient may experience emesis (vomiting).
- Technologist Preparation: The technologist should take steps to minimize possible radioactive contamination before the procedure begins.
