Test Preparation
To ensure accurate results, follow these preparation guideline:
1. Pre-Test Guidelines:
• Fasting:
Some facilities require fasting for 4-6 hours before the scan if contrast is used.
• Hydration:
Drink plenty of water before the test unless instructed otherwise.
• Medications:
Inform your doctor about 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, aneurysm clips, artificial joints, cochlear implants), as MRI uses strong magnetic fields.
• Claustrophobia:
If you are claustrophobic, discuss mild sedation options with your doctor before the test.
2. On the Day of the Test:
• Clothing & Accessories:
Wear comfortable, loose-fitting clothes 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.
3. During the MRV 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.
• The contrast dye will be injected through an IV line in your arm.
• You may feel a cool or warm sensation when the contrast enters your bloodstream.
• The MRI machine makes loud knocking or buzzing sounds; earplugs or headphones may be provided.
