How Long Does an MRI Take? Understanding the MRI Scan Process

Magnetic Resonance Imaging (MRI) is a pivotal medical imaging procedure that aids physicians in diagnosing and monitoring various health conditions. If you have an upcoming MRI, you might wonder about its duration. The time it takes to complete an MRI can vary based on several factors, including the type of scan and the area of the body being examined. This article delves into the MRI scan process, factors influencing its duration, typical times for different MRI procedures, and recent advancements in MRI technology.

What is an MRI?

MRI is a highly utilized diagnostic imaging technology that offers detailed images of the body’s internal structures, including soft tissues and organs, that don’t appear well on X-rays. By employing a strong magnetic field, MRI scans produce high-resolution images, making it an essential tool for healthcare providers. Unlike X-rays, there is no radiation involved in the MRI imaging process.

The MRI scan process involves several steps. Initially, you will lie down on a table that slides into the MRI machine. Staying as still as possible is crucial to ensure clear image capture. The machine produces a series of loud knocking sounds as it takes images, so you may be given earplugs or headphones to lessen the noise.

Preparation for the scan may involve removing any metal objects, as they can interfere with the magnetic field. You might also need to change into a gown to avoid any artifacts that could affect image quality. It’s important to inform the technologist if you have any metal implants, such as pacemakers or cochlear implants, as these could impact your eligibility for an MRI.

What Affects the Duration of an MRI?

Understanding the factors that influence MRI duration can help you better prepare for your appointment. The primary factors affecting how long an MRI scan takes include the size and complexity of the area being scanned, the type of MRI machine used, and the patient’s ability to remain still during the scan.

The size and complexity of the scanned area significantly impact the duration. Different body parts require different scan times. If specific abnormalities or structures need detailed examination, the scan may take longer.

The type of MRI machine also plays a role. There are various MRI machines, such as open, wide-bore and standard-bore MRI. Open MRI machines are better for individuals who feel claustrophobic or have trouble lying still for long periods. Wide-bore and standard-bore MRI machines offer more detailed images but might not be suitable for everyone. The choice of machine depends on your specific needs and the area being scanned.

Lastly, the patient’s ability to remain still during the scan is crucial. Movement can result in blurry images, requiring retakes and extending the process. Communicate any concerns or discomfort to the technologist beforehand, as they can provide guidance to help you stay still throughout the scan.

Typical Duration for Different MRI Procedures

Different MRI procedures can vary in duration depending on the specific body area being examined and the type of MRI machine. Here is a breakdown of the average times for various MRI scans:

Brain or Head MRI

A typical brain or head MRI takes 35 minutes on average. This procedure captures detailed images of the brain and surrounding structures, aiding in diagnosing various neurological conditions.

An advanced MRI machine, such as the 1.5T GE Signa Voyager Wide Bore at EmergeOrtho – Coastal Region, may take as little as 15 minutes for a brain or head MRI.

Spine or Knee MRI

If you have a spine or knee MRI scheduled, expect the scan to last 25 minutes on average. These scans are often used to assess joint injuries such as ligament tears or cartilage damage in the knee or diagnose conditions like herniated discs, spinal stenosis, or nerve impingement in the spine.

The 1.5T GE Signa Voyager Wide Bore at EmergeOrtho – Coastal Region may take as little as 7 minutes for a spine or knee MRI.

Shoulder or Wrist MRI

A shoulder or wrist MRI usually takes 25 minutes on average and is often used to diagnose a range of conditions including rotator cuff tears, labral tears, arthritis, carpal tunnel syndrome, tendonitis, or ligament sprains, which can cause pain, weakness, and other symptoms. which can cause pain, weakness, and other symptoms.

The 1.5T GE Signa Voyager Wide Bore at EmergeOrtho – Coastal Region may take as little as 15 minutes for a shoulder or wrist MRI.

These durations are general estimates, and the actual time needed for an MRI can vary based on the complexity of the case and individual patient factors. Some specialized MRI procedures may require more time.

Faster MRI Scans With Advanced Technology

Advancements in MRI technology have transformed the way we diagnose and treat medical conditions. One major area of progress is in speeding up MRI scans, allowing for quicker and more efficient imaging.

Gone are the days when MRI scans took hours. Thanks to advanced technology, MRI scan times have significantly decreased. This improvement is mainly due to faster imaging techniques and enhanced hardware, such as the cutting-edge 1.5T GE Signa Voyager Wide Bore MRI, and advanced imaging software such as GE Healthcare’s AIR Recon DL, now available to patients at EmergeOrtho – Coastal Region. With this new technology, an MRI scan may only take up to one-third of the time it typically takes.

Faster MRI scans offer several benefits. They minimize patient discomfort and anxiety, as patients spend less time inside the MRI machine. This is particularly advantageous for those who experience claustrophobia or have difficulty staying still for extended periods.

Moreover, quicker MRI scans improve workflow efficiency in healthcare facilities, enabling more patients to be scanned in a shorter timeframe. This translates to reduced waiting times for patients and better access to diagnostic services.

Emerging MRI technologies continue to push the boundaries of medical imaging. Ultra-high-field MRI scanners, for instance, offer superior image quality and enhanced diagnostic capabilities. Additionally, ongoing research into real-time MRI techniques aims to provide clinicians with the ability to monitor dynamic processes within the body.

Advancements in MRI technology have significantly shortened MRI scan times, benefiting both patients and healthcare providers. The use of advanced techniques and hardware has paved the way for faster imaging and improved diagnostic accuracy. As technology continues to evolve, the future of MRI holds great promise for further advancements in medical imaging.
