Full Body MRI Scan: What to Expect at Your First Appointment

Never had a full body MRI? Here's everything you need to know about preparing for, experiencing, and getting results from your first scan.

Key Takeaways

  • A full body MRI takes approximately 60 to 90 minutes
  • You'll need to remove all metal objects and wear provided clothing
  • The scanner is loud but you'll receive ear protection
  • There is no radiation — the scan uses magnetic fields
  • Results are typically available within 5 to 10 business days
  • No special preparation is needed for most scans (no fasting required at most clinics)

Before Your Appointment

Scheduling and Preparation

When you book your full body MRI, the clinic will provide preparation instructions. At most providers, preparation is minimal:

  • No fasting required at most clinics (some may request 2-4 hours of fasting)
  • Stay hydrated — drink water normally before your appointment
  • Avoid heavy meals right before the scan for comfort
  • Skip body lotion and deodorant on the day of your scan (some contain metals that interfere with imaging)
  • Arrive 15-30 minutes early for check-in and paperwork

What to Wear

You'll be asked to change into a gown or scrubs provided by the clinic, so wear whatever is comfortable to travel in. You will need to remove:

  • All jewelry (rings, earrings, necklaces, watches)
  • Hair clips, bobby pins
  • Belts with metal buckles
  • Underwire bras
  • Any clothing with metal zippers or buttons

Most clinics provide secure lockers for your belongings.

Important Medical Information

Before your scan, you'll fill out a safety questionnaire. Be sure to disclose:

  • Metal implants — pacemakers, cochlear implants, certain joint replacements, metal plates or screws
  • Pregnancy or possibility of pregnancy
  • Claustrophobia — let the clinic know in advance so they can accommodate you
  • Tattoos — some older tattoos contain metal-based inks (this rarely causes issues but should be mentioned)
  • Previous surgeries — especially those involving metal hardware

Some metal implants are MRI-compatible, but this must be verified before your scan.

Arriving at the Clinic

Check-In Process

When you arrive, expect a process similar to any medical appointment:

  1. Check in at reception and complete any remaining paperwork
  2. Review the safety questionnaire with a technologist
  3. Change into provided clothing in a private changing room
  4. Store your belongings in a secure locker
  5. Brief consultation with the technologist who will explain the scan

The MRI Room

The MRI machine is a large, tube-shaped magnet. Modern scanners are wider and shorter than older models, which helps reduce the enclosed feeling. The room will feel cool (MRI magnets require cooling systems) and the technologist will provide blankets if needed.

The Scanning Process

Getting Positioned

You'll lie on a padded table that slides into the MRI scanner. The technologist will:

  • Position you comfortably on the table
  • Provide ear protection (foam earplugs or noise-canceling headphones)
  • Give you a call button to press if you need to stop at any time
  • Place coils (special receivers) over the areas being scanned
  • Offer a blanket for comfort

Many clinics provide music through the headphones to help you relax during the scan.

During the Scan

Here's what the experience is like:

  • Duration: 60-90 minutes for a full body scan
  • Movement: You must lie as still as possible. Even small movements can blur the images
  • Sounds: The MRI is loud — you'll hear knocking, buzzing, and humming sounds. This is completely normal. The ear protection makes it manageable
  • Breathing: For some sections, the technologist may ask you to hold your breath briefly (10-15 seconds)
  • Communication: The technologist can hear and see you at all times through an intercom and window
  • Sensation: You won't feel anything from the magnetic field. Some people report a slight warming sensation, which is normal

The scan happens in segments. The table will move slightly between sections as different body regions are imaged. The technologist will communicate with you between segments.

Managing Claustrophobia

If you're prone to claustrophobia, these strategies help:

  • Close your eyes before entering the scanner and keep them closed
  • Focus on breathing — slow, deep breaths
  • Listen to music or a podcast through the provided headphones
  • Use the call button if you need a break
  • Ask about open MRI options if available (though image quality may differ)
  • Talk to your doctor about a mild anti-anxiety medication if needed (you'll need someone to drive you home)
  • Practice visualization — imagine yourself in a calm, open space

Most people who feel anxious about the enclosed space find that it's much more manageable than expected. The technologist is experienced in helping nervous patients feel comfortable.

After the Scan

Immediate Aftermath

When the scan is complete:

  • You can change back into your clothes immediately
  • There are no side effects or recovery time needed
  • You can drive yourself home and return to normal activities right away
  • You can eat and drink normally

Getting Your Results

The timeline for results varies by provider:

  • Prenuvo: Results in 5-10 business days, delivered through their patient portal
  • Ezra: Results in 5-7 business days with AI-enhanced analysis
  • Most other providers: 5-14 business days

Your results will typically include:

  1. A detailed radiology report from a board-certified radiologist
  2. A summary of findings in plain language
  3. Recommendations for any follow-up if needed
  4. Access to your images through an online portal

Understanding Your Results

Most full body MRI results will show some incidental findings — small cysts, benign growths, or normal anatomical variants that are common and not concerning. Your report will categorize findings by significance:

  • Normal findings — no action needed
  • Incidental findings — benign or not clinically significant, may require monitoring
  • Findings requiring follow-up — your provider will recommend next steps, which may include additional imaging or consultation with a specialist

If anything significant is found, the clinic will typically contact you directly rather than waiting for the scheduled results delivery.

Frequently Asked Questions

How often should I get a full body MRI?

Most providers recommend annual screening for ongoing monitoring. Your first scan establishes a baseline, and subsequent scans can detect changes over time.

Is a full body MRI painful?

No. The scan is completely painless. The only discomfort might be from lying still for an extended period.

Can I listen to music during the scan?

Yes, most clinics provide headphones with music or allow you to bring your own audio content on a non-metallic device.

What if something is found?

If an abnormality is detected, the clinic will recommend appropriate follow-up. This might include additional diagnostic imaging, blood work, or referral to a specialist. Early detection is the entire point — finding issues early means more treatment options and better outcomes.

Is the scan safe for everyone?

MRI is safe for most people. The main exceptions are individuals with certain metal implants (pacemakers, some cochlear implants), severe claustrophobia that cannot be managed, and in some cases, pregnancy (discuss with your doctor).
