MRI Preparation and Results Timeline: Week-of, Day-of and After
A practical timeline for preparing for an MRI, from authorization and fasting to the scan day, report turnaround and follow-up with your doctor.

Preparing for an MRI mostly means confirming price and coverage ahead of time, telling the center about implants and health conditions, following any fasting or contrast instructions, wearing metal-free clothing and arranging a ride if you will be sedated. The report usually goes to your ordering doctor within a few business days, and a follow-up appointment turns the findings into a plan. This timeline organizes the tasks by when to do them, so nothing is left to the last minute.
One to two weeks before
Confirm the order. Verify the scan name, body area, contrast and the CPT code with your doctor. Ask where the order was sent.
Lock in price and coverage.
- Get a written price or Good Faith Estimate. See Good Faith Estimate for MRI.
- If insured, confirm network status for the facility and radiologist, and prior authorization. Note the authorization number.
- If paying over time, arrange a plan before the scan; see payment plans and financing.
List your devices and history. Collect implant cards, surgical dates and names of devices. Note allergies, kidney disease, pregnancy and past contrast reactions.
Ask about comfort. If you are claustrophobic, ask about wide-bore scanners and a sedative. If a sedative is prescribed, arrange a driver.
Request prior images. If you've had earlier scans elsewhere, ask for copies or have them sent so the radiologist can compare. Comparison can improve accuracy.
Two to three days before
- Re-read the center's instructions.
- Confirm your appointment time and location, parking and arrival time (often 15 to 30 minutes early).
- If you were asked to get a kidney function blood test before contrast, make sure it is done and sent.
- Ask your doctor whether to continue or hold any medicines on the day. Do not stop prescribed medicine on your own.
The day before
- Fasting: if your scan requires it, plan your last meal. Abdominal and pelvic scans often ask you to avoid food for a few hours, but follow your center's exact instruction.
- Hydration: unless told otherwise, stay hydrated, which helps with IV placement and contrast clearance.
- Clothing: choose clothes without zippers, metal buttons, metallic threads or underwire. Many people wear athletic wear without metal.
- Avoid: lotions, creams or makeup with metallic particles near the scan area, if the center advises it.
- Charge your phone, and prepare the checklist, your ID, insurance card and the order.
The day of the scan
- Arrive early to complete forms. Read the financial form and compare it with your estimate.
- Leave metal at home or in a locker: jewelry, watches, hairpins, hearing aids, dentures if removable, belts, keys, cards with magnetic strips and phones.
- Complete the safety questionnaire honestly.
- Ask any final questions, such as how long the scan will take and what to do if you feel unwell.
- Use the bathroom before the scan.
- Take sedation only as directed and do not drive afterward.
After the scan
- Resume normal activity unless sedated or told otherwise. After a sedative, rest and don't make major decisions until fully awake.
- If you got contrast, drink fluids if the center advises and watch for rash, itching or swelling at the injection site.
- Ask how to get your report and images and when your doctor will have them.
- Keep your paperwork, including the estimate, consent forms and the receipt.
Results timeline
| Stage | Typical time (varies) |
|---|---|
| Radiologist reads the study | Same day to 2 business days |
| Report sent to ordering doctor | 1 to 3 business days |
| Urgent or emergency findings | Called to the doctor promptly |
| Patient portal release | May be immediate or after a short delay |
| Doctor's review with you | Often a few days to a couple of weeks |
| Bills arrive | Center and radiologist bills within weeks; insurer's Explanation of Benefits after claim processing |
If your doctor has not contacted you within the time they indicated, call the office rather than assuming no news is good news. Delays occur in busy practices.
How to read the report (carefully)
Reports use technical terms. Common phrases such as "mild degenerative changes," "disc bulge" or "small effusion" are frequent findings, even in people without symptoms. Don't panic over single words. Ask your doctor:
- What did the scan show that explains my symptoms?
- What findings are incidental or likely unrelated?
- What are the next steps, and is any follow-up scan needed?
- Do I need a second opinion or a subspecialist read?
If you notice an error in your report, such as the wrong side of the body, tell the center and your doctor right away.
Recovery
An MRI itself has no recovery period. If you had sedation, plan a restful day. If you had contrast, most people feel normal. If you experienced anxiety, consider what helped and tell the center for any future scans.
Follow-up and second opinions
You may request a second read of your images, often at an academic center, especially for complex findings. Ask your doctor to request it or obtain a copy of images and report yourself. Many centers provide a disc or portal link for a fee or free of charge; ask before your scan.
Worked example (illustrative)
Scan on Tuesday at 9:00. Monday: you confirm the authorization number, wear athletic clothing without metal and charge your phone. Tuesday: you arrive at 8:40, finish forms, scan 9:10 to 9:50. The radiologist reads that afternoon; the report reaches your doctor Wednesday. The doctor's office calls Thursday to schedule a visit for the following week. The center's bill arrives two weeks later and matches the $580 estimate you saved. This is an example of a typical flow, not a guarantee.
When to consult a professional
Contact your doctor for questions about preparation, medications, fasting and results. Contact the center for logistics and billing. Call 911 for emergencies.
Frequently asked questions
Can I take my regular medicines before an MRI?
Usually yes, but ask your doctor and the center, especially for scans needing fasting or sedation.
How early should I arrive?
Often 15 to 30 minutes before the appointment for forms and screening.
Can I get my images?
Yes, ask for a disc or portal link. Some centers charge a small fee.
What if I get an anxious feeling the night before?
Contact your doctor about options, and ask the center about a wide-bore scanner or coaching.
