Test Preparation
To ensure accurate results, follow these preparation guideline:
- Pre-Test Guidelines:
• Fasting:
If contrast dye is required, you may need to fast for 4-6 hours before the test.
If no contrast is used, fasting is usually not necessary.
Medications:
Inform your doctor about all medications you are taking.
If you have kidney disease, a kidney function test (creatinine test) may be needed before the scan, as contrast dye can affect kidney function.
• Allergy & Medical History:
Notify your doctor if you have a history of allergic reactions to contrast dye.
Inform your doctor if you have any metal implants (pacemaker, stents, artificial joints, etc.) since MRI may not be safe.
• Claustrophobia:
If you are claustrophobic, talk to your doctor about mild sedation options. - On the Day of the Test:
• Clothing & Accessories:
Wear comfortable, loose-fitting clothes without metal parts (zippers, buttons, or wires).
Remove jewelry, watches, hearing aids, credit cards, and other metallic objects before the test.
• Avoid Caffeine & Alcohol:
Avoid caffeine and alcohol 24 hours before the test, as they can affect blood circulation.
• Hydration:
Drink plenty of water before the test, especially if contrast dye is used. - During the MRA Scan:
• The test takes 30-60 minutes, depending on the complexity of imaging.
• 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 may feel a cool sensation when the dye enters your body.
• The MRI machine makes loud knocking or buzzing noises during the scan; earplugs or headphones may be provided.
