Test Preparation
To ensure accurate results, follow these preparation guideline:
1. 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 may not be necessary.
• Hydration:
You may be asked to drink plenty of water before the scan to ensure good urine flow for better imaging.
• Bladder Preparation:
You may be required to arrive with a full or partially full bladder to enhance image quality.
• Medications:
o Inform your doctor about any medications, especially:
Diuretics (may affect urine flow)
Blood thinners (if biopsy is needed)
Kidney medications
If you have kidney disease, a creatinine test may be required before receiving contrast dye.
• 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) 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 loose-fitting, comfortable clothing without metal parts (zippers, buttons, or wires).
Remove jewelry, watches, hearing aids, and metallic objects before the test.
• Avoid Caffeine & Alcohol:
Avoid caffeine and alcohol for 24 hours before the test, as they may affect kidney and liver function.
• Diabetic Patients:
If you have diabetes and take metformin, consult your doctor, as it may need to be stopped before the test.
3. During the MR Urography + MRI Abdomen Scan:
• The test takes 45-90 minutes, depending on the imaging type.
• 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 sensation when the dye enters your body.
• The MRI machine makes loud knocking or buzzing sounds; earplugs or headphones may be provided.
