Test Preparation
To ensure accurate results, follow these preparation guideline:
- Fasting:
• Not required for a plain (non-contrast) scan.
• If a contrast-enhanced scan is needed, fast for 4–6 hours before the test. - Clothing & Accessories:
• Wear loose, comfortable clothing.
• Remove all metal objects from the head area, including eyeglasses, contact lenses, earrings, hairpins, and dentures. - Medical History:
• Inform the doctor if you:
Are pregnant or suspect pregnancy.
Have allergies to contrast dye, iodine, or seafood (if contrast is used).
Have kidney disease (contrast may require kidney function tests).
Have a history of eye surgeries or implants. - During the Scan:
You will lie still on the CT table while images are taken in both axial and coronal planes.
If contrast dye is used, it will be given via an IV injection to highlight blood vessels and soft tissues.
The scan is quick (10–15 minutes) and painless. - After the Scan:
Normal activities can be resumed immediately if no contrast was used.
If contrast was used, drink plenty of water to help flush it out.
Mild discomfort or warmth from the contrast is normal but should subside quickly.
