Open MRI: Balancing Advantages and Disadvantages

While Open MRI scanners provide an attractive alternative to traditional enclosed MRI machines—particularly for claustrophobic patients or those with larger body types—it's essential to acknowledge their inherent limitations. At Great Lakes Medical Imaging (GLMI), we are committed to empowering our patients to make well-informed healthcare decisions, which includes understanding the potential drawbacks of various imaging methodologies. In this article, we delve into some of the potential limitations of open MRI.

Image Quality and Open MRI

Perhaps the most significant drawback of open MRI scanners, compared to conventional MRI machines, is the variance in image quality. Traditional MRI scanners usually possess a higher magnetic field strength, typically ranging between 1.5 to 3.0 Tesla, leading to more intricate images. On the contrary, open MRI machines generally function at a lower magnetic field strength, which could occasionally result in less detailed images (RadiologyInfo, 2021).

Longer Scanning Durations

Owing to the lower magnetic field strength, open MRI scanners may need additional time to capture the requisite images. This could potentially extend scanning durations, possibly leading to discomfort for some patients, notwithstanding the more spacious design.

Restricted Applications for Certain Procedures

Certain procedures and diagnoses may not be suitable for open MRI. For instance, functional MRI (fMRI), a technique employed to measure and visualize brain activity, or Magnetic Resonance Angiography (MRA), used to examine blood vessels, may necessitate the superior resolution imaging offered by a traditional MRI (American College of Radiology, 2021).

Conclusion

While open MRI scanners propose a more comfortable and less claustrophobic experience, it is crucial to comprehend their potential shortcomings. Your physician and radiologist will contemplate these factors, along with your personal comfort and needs, when deciding on the most appropriate imaging method for your situation.

If you're scheduled for an MRI scan and harbor reservations about using a traditional MRI machine, we strongly urge you to discuss these concerns with your doctor or connect with our team at GLMI.
