Description
Test Preparation
- Diet & Fasting (Before the Scan)
Fasting: No food or drinks (except water) for 4–6 hours before the scan.
Hydration: Drink plenty of water unless otherwise instructed. - Drinking the Oral Contrast (Before the Scan)
You will be given a contrast solution (usually barium sulfate or iodine-based dye) to drink 30–60 minutes before the scan.
The contrast coats the digestive tract, making it more visible in the CT images.
Some patients may need to drink the contrast in divided doses over 1–2 hours. - Medical Considerations
Inform the doctor if you:
• Are pregnant or breastfeeding
• Have kidney disease (a kidney function test may be needed)
• Have allergies to contrast dye, iodine, or shellfish
• Have a history of digestive disorders - During the Scan
You will lie on your back on the CT table.
The scan is quick, usually 10–20 minutes.
You may be asked to hold your breath briefly for clearer images. - After the Scan
Drink plenty of water to help flush the contrast dye from your system.
You may experience mild bloating or loose stools, which is normal.
Resume normal activities and diet unless instructed otherwise.
