Test Preparation
To ensure accurate results, follow these preparation guideline
- Before the Scan:
Fasting: Not required for a plain (non-contrast) scan. If contrast is needed, fast for 4–6 hours.
Clothing & Accessories: Remove eyeglasses, contact lenses, jewelry, or any metal objects near the eyes and head. - Medical History: Inform the doctor if you:
• Are pregnant or suspect pregnancy
• Have a history of allergies to contrast dye (if contrast is used)
• Have any eye conditions or prior surgeries - During the Scan:
You will lie still on the CT table, and the scanner will take images in axial and coronal planes.
If contrast dye is used, it may be given orally or through an IV injection for better visualization of soft tissues and blood vessels.
The scan usually takes 10–15 minutes. - After the Scan:
No recovery time is needed for a plain scan; you can resume normal activities.
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.
