X-ray of the stomach and the duodenum
- Prior appointment: required
- Preparation: 4 hours of fasting
- Duration of the investigation: about 10 minutes
- Contrast medium: required (barium)
An X-ray examination of the stomach and the duodenum is a fluoroscopy-guided investigation for which the patient is asked to swallow contrast medium. This investigation permits the examiner to assess the stomach and the duodenum.
Course of the investigation:
The patient is first given a small cup with an effervescent powder, followed by a small sip of water, and then a cup of contrast medium. The powder dilates the stomach. This may cause belching of air, which should be suppressed as effectively as possible in order to ensure an accurate diagnosis. Thereafter you will be asked to lie supine and turn around once to distribute the contrast medium in the stomach. Images are then obtained in various positions.
