Most MRI preparation in Miami takes about ten minutes the night before.
It comes down to food rules, metal, and paperwork.
For most scans, you can eat, drink, and take your medicine as usual.
The bigger risk is forgetting something small, like a skin patch or an implant card, which can delay your scan.
Can You Eat and Drink the Night Before an MRI?
Yes. For most MRI scans, you can eat dinner, drink water, and take your medicine as normal.
The American College of Radiology and RSNA note on RadiologyInfo.org that food rules vary by exam and facility. So the answer depends on the body part.
Knee, brain, or spine scans usually have no food rules. Belly scans are different.
Food moving through your bowel can blur those images, so an abdominal MRI or MRCP often comes with a fasting window of about 8 hours.
Check the body part on your doctor’s order tonight:
- Abdomen, liver, kidneys, or bile ducts: open the abdomen MRI prep page before bed.
- Head: the brain MRI instructions tell you what applies.
- Neck or back: here is how each spine MRI section differs.
Your MRI Preparation in Miami Starts With a Metal Check
The MRI uses a very strong magnet, so metal is the main thing to sort out tonight. We provide scrubs for some exams, so your outfit is the easy part.
Do these before bed:
- Take out piercings, rings, and hair clips now.
- Skip makeup tomorrow. Some makeup contains metal that blurs the image.
- Leave your watch, fitness tracker, and jewelry at home.
- Some tattoo ink contains iron. Heating is rare, but speak up if a tattoo feels warm.
What If You Have an Implant or Old Metal in Your Body?
Tell the center before your scan day.
Many implants are fine in an MRI, but the team must first confirm the exact type and its safety status.
Tonight, find the card that came with your device. This matters most for pacemakers, defibrillators, nerve stimulators, cochlear implants, and brain aneurysm clips.
The FDA’s MRI safety page is clear on this point: a device with an unknown MRI status should be treated as unsafe.
Arriving without that card can delay your scan.
Also mention any welding or metal grinding work, a past metal sliver in your eye, or shrapnel.
Metal near the eye can move or heat up.
This post on implants and metal fragments covers what happens next.
Medications, Skin Patches, and Sedatives
Keep taking your regular medicine unless your doctor told you to stop. The one item to check is any medicated skin patch.
In 2009, the FDA warned that some nicotine and pain patches have hidden metal in the backing that can heat up and burn the skin.
Tell the scheduler and the technologist, and ask your doctor when to take the patch off and when to put on a new one.
If closed spaces make you anxious, ask your doctor for a mild sedative before scan day.
If you take one, book a ride home tonight. An open MRI option helps some patients, but not every exam can be done on an open machine.
If your scan uses contrast dye, tell the team about kidney disease, past dye reactions, or a possible pregnancy. You may need a blood test to check your kidneys first.
What Paperwork Should You Pack Before Bed?
Pack one bag tonight with these items:
- Photo ID and insurance card.
- Your doctor’s order for the MRI.
- Your implant card or device pamphlet, if you have one.
- A list of your current medicines, including patches.
- Reports or discs from past scans done elsewhere.
- Your claim number and adjuster’s contact, if the scan is part of work injury claims. The carrier usually has to approve the scan first.
Plan Your Miami Morning Around the Scan
Most MRI exams take 30 to 60 minutes. Add time for the safety form and changing, and plan to arrive 30 minutes early.
Know your suite before you leave. Our Miami Center at 7101 SW 99 Avenue has three suites: 106 is the main center, 108 is women’s wellness, and 109 is oncology and cardiology.
One patient review noted that a location with three doors made the right entrance hard to find, so ask when you confirm.
Our staff can walk you through prep in English or Spanish.
When Night-Before Prep Is Not Enough
This checklist fits a routine outpatient MRI in Miami-Dade. It does not replace your doctor’s instructions. Call before your scan if:
- You have diabetes and were told to fast.
- You are pregnant or might be.
- You have kidney disease, and your scan uses contrast.
- You cannot find your implant card.
If you have sudden chest pain, weakness on one side, or trouble speaking, skip the appointment and call 911.
Set Your MRI Bag by the Door Tonight
Put your ID, insurance card, order, and implant card in one bag before bed.
