Test Preparation
To ensure accurate results, follow these preparation guideline:
- Fasting: Fast for 4–6 hours before the test (to ensure clear imaging and avoid complications with contrast dye).
- Hydration: Drink plenty of water before the scan (unless instructed otherwise).

- Medical History: Inform your doctor if you:
• Are pregnant or breastfeeding
• Have kidney disease (a kidney function test may be required)
• Have diabetes (especially if taking metformin)
• Have a history of allergies to contrast dye, iodine, or seafood - Allergy Precautions: If you have a known allergy to contrast dye, your doctor may prescribe antihistamines or steroids before the scan.
- Breathing Instructions: You may be asked to hold your breath for a few seconds during the scan to get clearer images of the blood vessels.
- Heart Rate Management (if needed): If the test is being done to evaluate coronary arteries, beta-blockers may be given to slow the heart rate for clearer images
