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 scan.
• Hydration:
Drink plenty of water before the test unless instructed otherwise.
• Medications:
Inform your doctor about any blood thinners, diabetes medications (e.g., Metformin), or kidney medications.
If you have kidney disease, a kidney function test (creatinine test) may be required before contrast administration.
• Allergy & Medical History:
Inform your doctor if you have contrast dye allergies.
Notify your doctor if you have metal implants (pacemakers, artificial joints, aneurysm clips, stents, or dental implants), as MRI uses strong magnetic fields.
• Claustrophobia:
If you are claustrophobic, discuss mild sedation options with your doctor before the test.
On the Day of the Test:
• Clothing & Accessories:
Wear loose-fitting, comfortable clothing without metal parts (zippers, buttons, or wires).
Remove jewelry, hearing aids, glasses, and metallic objects before the scan.
• Avoid Caffeine & Alcohol:
Avoid caffeine and alcohol for 24 hours before the test, as they may affect blood circulation.
During the MRA Scan:
• The scan takes 30-60 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.
You may feel a cool or warm sensation when the dye enters your bloodstream.
• The MRI machine makes loud knocking or buzzing sounds; earplugs or headphones may be provided.
