Preparation

• You must have fasted before an RX large intestine: do not eat, drink, or smoke for six hours before the examination.

  • The insertion of the tube may cause some discomfort.
  • You may temporarily experience intestinal cramps while the intestine is being filled.
  • In case of severe cramps, an antispasmodic will be administered through your arm.
• You will need to change positions multiple times: on your stomach, back, side, standing, and lying down.
• During the imaging process, you must remain still and briefly hold your breath.
• After the examination, it is recommended to go to the toilet.
