Test Preparation
To ensure accurate results, follow these preparation guideline:
- Fasting
• Fasting for 4-6 hours before the test may be required if contrast is used.
• If no contrast is needed, fasting is usually not necessary. - Hydration
• Drink plenty of water before the test unless instructed otherwise.
• After the scan, staying hydrated helps flush out the contrast dye from your system. - Medications
• Take your regular medications unless advised otherwise.
• Inform your doctor if you are taking blood thinners, diabetes medication (e.g., Metformin), or have kidney disease (as contrast dye requires caution in these cases). - Allergies & Medical Conditions
• Inform the radiologist if you have a history of contrast dye allergies or kidney issues.
• If you have asthma, breathing difficulties, or past allergic reactions, extra precautions may be needed. - Clothing & Accessories
• Wear loose, comfortable clothing without metal (zippers, jewelry, belts, underwires, etc.).
• You may be asked to change into a hospital gown. - Implant or Device Precautions
• Inform the technician if you have metal implants, pacemakers, aneurysm clips, or any metallic objects in your body, as they can interfere with the MRI. - Claustrophobia & Anxiety
• If you have claustrophobia, discuss with your doctor about a mild sedative before the test.
• Some facilities offer open MRI options for comfort. - During the Procedure
• You will lie on a table that slides into the MRI scanner.
• If contrast dye is needed, it will be injected into a vein (usually in the arm) to enhance imaging.
• The machine makes loud noises; earplugs or headphones may be provided.
• The scan typically takes 45-60 minutes. - After the Test
• No downtime; you can resume normal activities unless sedated.
• Drink plenty of water to help eliminate the contrast dye.
• Results are usually available within a few days
