Test Preparation
To ensure accurate results, follow these preparation guideline:
- Pre-Test Guidelines:
• Fasting:
If contrast dye is used, you may need to fast for 4-6 hours before the test.
If no contrast is used, fasting is usually not required.
• Medications:
Inform your doctor about all medications you are taking.
If you have kidney disease, contrast dye might not be recommended, so a kidney function test (creatinine test) may be required.
• Allergy & Medical History:
If you have a history of allergic reactions to contrast dye, let your doctor know.
Inform your doctor if you have kidney problems, asthma, or any metal implants (pacemaker, artificial joints, stents, etc.) as MRI may not be safe in such cases.
• Claustrophobia:
If you have claustrophobia, discuss sedation options with your doctor before the test. - On the Day of the Test:
• Clothing & Accessories:
Wear comfortable, loose-fitting clothes without metal zippers, buttons, or wires.
Remove jewellery, watches, hearing aids, credit cards, and any metallic objects before the test. - Avoid Caffeine & Alcohol:
Avoid caffeine and alcohol 24 hours before the test as they can affect blood vessel function.
• Hydration:
Drink plenty of water before the test, especially if contrast dye is used. - During the MRA Scan:
• The test takes 30-90 minutes, depending on the area being examined.
• You will lie still inside the MRI machine while images are taken.
• If contrast dye is used, it will be injected through an IV line in your arm. You might feel a cool sensation when the dye enters your body.
• You will hear loud knocking or buzzing noises from the MRI machine. Earplugs or headphones may be provided.
