Test Preparation
Proper preparation is important for accurate results. Here’s what to expect:
General Preparation:
• Fasting:
• Do not eat or drink for at least 6–8 hours before the test.
• This ensures the stomach and intestines are empty for clear imaging.
• Medication:
• Continue your usual medications unless advised otherwise by your doctor.
• Diabetic patients may need special instructions regarding insulin or oral medications.
• Allergy Disclosure:
• Inform the doctor if you have any allergies, especially to iodine or contrast agents.
• Pregnancy:
• Let the technician or radiologist know if you are or might be pregnant.
Before the Test (if bowel imaging is planned):
• A laxative or enema may be prescribed the night before, depending on the area being examined.
During the Test
• You will be asked to drink Gastrografin, a clear or slightly yellow liquid with a sweet-bitter taste.
• X-rays are then taken in various positions (standing, lying down, side-lying) to track the movement of the contrast.
• You may be asked to change positions or hold your breath to get clear images.
After the Test
• Hydrate well to help flush the contrast out of your body.
• You may notice loose stools or mild diarrhea—this is normal with Gastrografin.
• Report any allergic reaction (itching, rash, breathing difficulty) to your doctor immediately, although such reactions are rare.
