How Long Does a Full Body MRI Take? Duration & What to Expect

One of the most common questions patients ask before scheduling a full body MRI is how long the scan will take. A full body MRI typically requires 60 to 90 minutes of actual scanning time, though the total appointment can last up to two hours when preparation and positioning are included. Understanding the timeline helps patients prepare mentally and physically for a comfortable experience.

How Long Is the Actual Scan?

The scanning portion of a full body MRI lasts between 60 and 90 minutes. This time varies depending on how many body regions are included in the scan protocol. A basic full body scan covering the brain, spine, and abdomen typically falls closer to 60 minutes, while a comprehensive scan that includes the chest, pelvis, and major joints may take closer to 90 minutes.

If contrast dye (gadolinium) is required for enhanced visualization of certain areas, the scan may take an additional 10 to 15 minutes. The contrast is administered intravenously partway through the scan, and additional image sequences are captured afterward to evaluate blood flow and tissue characteristics.

"The scan duration is something patients ask about in almost every consultation," explains Dr. Osama Elzamzami, Consultant Radiologist at DCDC. "I always reassure them that 60 to 90 minutes may sound long, but we build in natural pauses between body regions. Most patients tell us afterward that it was far more manageable than they expected."

Full Body MRI Duration Breakdown by Region

A full body MRI is essentially a series of regional scans performed in one session. Each body region requires specific imaging sequences that take a defined amount of time. The following breakdown provides an approximate idea of how long each region adds to the total scan time.

Why Does a Full Body MRI Take Longer Than a Regular MRI?

A standard single-region MRI scan (such as a brain MRI or knee MRI) typically takes 20 to 45 minutes. A full body MRI takes significantly longer because it covers multiple body regions, each requiring its own set of imaging sequences and patient repositioning.

• Multiple body regions: Each region of the body requires dedicated imaging sequences optimized for that specific anatomy. Scanning the brain requires different settings than scanning the abdomen or a knee joint.
• Repositioning between regions: The MRI coils (specialized equipment placed over the body area being scanned) may need to be adjusted or changed between regions, adding brief pauses to the scan.
• Image quality requirements: Each region must produce diagnostic-quality images. The MRI technologist checks image quality between sequences and may need to repeat certain acquisitions if motion artifacts are detected.
• Contrast timing: If contrast dye is used, the technologist must wait for the contrast to circulate before capturing enhanced images, which adds time to the overall procedure.

What Happens During a Full Body MRI?

Understanding the step-by-step process of a full body MRI helps reduce anxiety and ensures patients know what to expect throughout the appointment.

Before the Scan (15-20 Minutes)

Patients arrive 15 to 20 minutes before their scheduled scan time. During check-in, the radiology team reviews a safety questionnaire to confirm there are no contraindications such as metal implants, pacemakers, or other devices that may be affected by the magnetic field. Patients change into a hospital gown and remove all metal items including jewelry, watches, belts, and hair clips.

During the Scan (60-90 Minutes)

The patient lies on a padded table that slides into the MRI machine. Earplugs or headphones are provided because the machine produces loud knocking and humming sounds during scanning. A call button is given to the patient so they can communicate with the technologist at any time.

The technologist operates the scanner from an adjacent room and communicates with the patient through a microphone. Between scanning sequences, patients may hear brief pauses followed by different patterns of sounds as the machine adjusts for each body region. The most important instruction throughout the scan is to remain as still as possible.

After the Scan (5-10 Minutes)

Once all scanning sequences are complete, the table slides out and the patient can change back into their clothing. If contrast dye was administered, patients are typically observed for a few minutes to ensure there is no adverse reaction. Most patients can return to normal activities immediately after the scan.

Tips for a Comfortable Full Body MRI Experience

Spending 60 to 90 minutes inside an MRI machine can feel challenging, especially for first-time patients. These practical tips can help make the experience more manageable.

• Practice relaxation breathing: Slow, deep breaths help reduce anxiety and keep the body still. Focus on breathing rhythmically throughout the scan.
• Close your eyes: Many patients find it helpful to keep their eyes closed throughout the scan to avoid feeling enclosed. Visualize a calm place or focus on the breathing rhythm.
• Use the provided earplugs or headphones: MRI machines are loud. The ear protection significantly reduces noise and some centers offer music through headphones.
• Avoid caffeine beforehand: Caffeine can increase restlessness and make it harder to remain still for an extended period.
• Wear comfortable clothing: Avoid clothing with metal zippers, snaps, or underwire. Many centers provide a gown, but comfortable cotton clothing without metal is also acceptable.
• Consider an open MRI: If claustrophobia is a concern, ask about open MRI options which provide a more spacious scanning environment.

One patient who visited DCDC for a full body MRI had a history of significant claustrophobia and was genuinely anxious about spending up to 90 minutes inside the scanner. Before the appointment, our radiology team spoke with her by phone to explain the process step by step and discuss comfort options. On the day of the scan, the technologist provided earplugs with calming music, explained each phase before it began, and checked in regularly between body regions. The patient later shared that the natural breaks between regions — where the table repositions and the technologist adjusts coils — gave her moments to regroup. She completed the entire scan without requesting a stop and told our team she was surprised by how manageable the experience was with proper preparation and support.

When Will Results Be Ready?

After the scan is complete, the images are reviewed by a consultant radiologist who prepares a detailed written report. At Doctors Clinic Diagnostic Center, full body MRI reports are typically available within 24 to 48 hours. The report is shared with both the patient and their referring physician.

Because a full body MRI generates hundreds of images across multiple body regions, the radiologist interpretation takes longer than a single-region scan. This thoroughness ensures that every area is carefully evaluated and any findings are properly documented.

Final Thoughts

A full body MRI is a thorough diagnostic procedure that takes 60 to 90 minutes of scanning time. While this is longer than a single-region MRI, the comprehensive coverage it provides across multiple body systems makes it a valuable tool for detailed health assessment. Knowing what to expect and how to prepare can make the experience significantly more comfortable.

At Doctors Clinic Diagnostic Center in Dubai Healthcare City, our team works to make every full body MRI as efficient and comfortable as possible. From streamlined preparation to timely reporting, we focus on delivering a smooth patient experience alongside accurate diagnostic results.
