How Long Do Full Body MRIs Take? Here’s What to Expect
How long do full body mris take is one of the first things people want to know before booking a scan. Here’s the short answer:
| Scan Type | Typical Duration |
|---|---|
| Full body MRI (general range) | 60 – 75 minutes |
| Total appointment time (check-in + scan + recovery) | ~2 hours |
If you’re someone who wants to get ahead of potential health problems – a family history of cancer, an unexplained symptom, or just the need for peace of mind – knowing how much time to block off matters. You don’t want surprises on the day of your scan.
This guide breaks down exactly what drives full body MRI scan times, how they compare to targeted scans, and what you can expect from start to finish.
Understanding the Duration: How Long Do Full Body MRIs Take?
When we talk about a “full body” scan, we aren’t just taking one giant photo. Instead, the MRI machine captures a series of detailed “slices” across multiple vital organs and systems. Because of this complexity, the question of how long do full body mris take usually lands between 60–75 minutes for the active scanning portion. At MRI Wellness, our comprehensive protocols are designed to be efficient yet thorough, typically averaging about 60 to 90 minutes.
Unlike a standard diagnostic MRI that might only look at a painful knee, a full body screening is a tool for preventative medicine. We use it for holistic health assessments to find cancer lesions, aneurysms, or organ abnormalities in asymptomatic individuals—people who feel perfectly fine but want to stay that way.
Factors That Influence Total Examination Time
While the time inside the magnet is the main event, your total time at our North Charleston facility involves a few other steps. To ensure the highest image quality and a smooth experience, we recommend looking at the “Total Examination Time,” which is usually around two hours.
Several logistical factors influence this:
- Arrival and Registration: We ask patients to arrive 15 to 30 minutes early. This gives us time to review your medical history, check for metallic implants, and help you change into a hospital gown.
- Metal Removal: MRI machines use incredibly strong magnets. Removing jewelry, piercings, hair clips, and even certain types of makeup (which can contain metallic particles) is essential for safety and clear images.
- Machine Technology: Newer, high-field MRI scanners can often complete sequences faster than older models without sacrificing detail.
- Fasting Requirements: For certain abdominal or “torso” scans, you might be asked to fast for 4 to 8 hours to ensure the gallbladder and digestive organs are clearly visible.
- Breathing Instructions: During scans of the chest or abdomen, you’ll hear us over the intercom asking you to hold your breath for up to 30 seconds. Following these instructions perfectly helps prevent “motion blur” on the images, which saves time by preventing us from having to redo a sequence.
Comparing Full Body Scans to Targeted MRI Procedures
It helps to put the duration of a full body scan into perspective by comparing it to the targeted scans your doctor might order for a specific injury. Generally, a full body scan is like a marathon, while a targeted scan is a sprint—but the sprint isn’t always as short as you’d think!
- Brain or Head MRI: Typically takes 30 to 60 minutes. A limited “quick-sequence” brain scan can be done in under 15 minutes, but a full diagnostic look takes longer.
- Spine MRI: Whether it’s the lumbar (lower) or cervical (neck) spine, these usually take 30 to 45 minutes per section.
As you can see, a full body scan is incredibly efficient. Instead of spending 45 minutes on five different days to check your head, spine, and organs, you can get a comprehensive view of your entire system in one 90-minute session.
Frequently Asked Questions
How soon will I get my results?
We know the wait for medical news can be stressful. After your scan is complete, a radiologist (a doctor specializing in reading these images) will analyze the hundreds of pictures we captured.
At MRI Wellness, we aim to provide a consultant report and access to your digital image portal within 3-5 working days. Once the report is ready, we schedule a follow-up appointment to discuss the findings and any necessary next steps.
Is a full body MRI covered by insurance?
This is a common question. Because full body MRIs are often used for proactive screening rather than diagnosing an existing symptom, they are frequently considered “elective” and are not covered by standard health insurance.
However, many of our patients view this as a vital preventative investment in their long-term health. The good news? These scans are typically eligible for Health Savings Account (HSA) or Flexible Spending Account (FSA) funds. We provide transparent, out-of-pocket pricing so there are no surprise bills later.
One of the best things about MRI is that it uses no radiation. Unlike CT scans or X-rays, MRI uses magnetic fields and radio waves, making it safe for repeated use in monitoring health.
The primary “risks” are related to the magnetic field. People with certain metallic implants (like older pacemakers or brain aneurysm clips) may not be able to have an MRI. Pregnant women should always consult their obstetrician first, though MRI is generally considered safe after the first trimester. If contrast is used, there is a very small risk of sensitivity or an allergic reaction, which our staff is fully trained to handle.
Conclusion
Investing 60-75 minutes in a full body MRI can change the trajectory of your health. By catching “silent killers” like aneurysms or early-stage tumors when they are most treatable, you aren’t just saving time in the long run—you might be saving your life.
At MRI Wellness, we’ve combined the most advanced diagnostic power with a comfort-focused, anxiety-reducing environment right here in North Charleston. Whether you are dealing with unexplained fatigue or simply want the peace of mind that comes with a clean bill of health, we are here to help.
