RX small intestine with probe

Medical prescription required

This examination always requires a prescription from your doctor. Bring this prescription on the day of the examination.

Preparation

• You must have fasted for an RX small intestine: do not eat, drink, or smoke for six hours before the examination.
• The digestive tract must be completely empty for clear imaging. Therefore, along with your appointment confirmation, you will receive dietary instructions and the appropriate laxative.
• Inform the nurse before the examination if you think you might be pregnant.

Course

Duration: approximately 45 minutes to 1 hour.

• Your throat will be numbed locally with a spray.
• The radiologist inserts a small tube through the nose (sometimes the mouth) into the small intestine.
  • The insertion of the tube may cause some discomfort.
• The contrast fluid is then introduced into the intestine through the tube.
• X-ray images of the small intestine are taken.
  • During imaging, you must remain still and briefly hold your breath.
