There are three different types of open MRI machines. People might not know this but using an open MRI can give more accurate and faster result than a closed MRI. Although still closed in the traditional sense these MRI machines have larger internal dimensions decreasing the likelihood of panic attacks and claustrophobia inside the machines and allowing for larger patients to fit.
Older open type scanners did not produce very good quality images due to a reduced number of magnets. Compared with the donut-shaped closed systems the benefits of open MRI machines can include. As mentioned above open MRI machines are made with a wider opening to improve patient comfort.

Open systems as the name suggests are almost open all the way around the patient closed-bore systems have the tunnel design. Prior to the introduction of the Open MRI low field system larger patients were simply not scanned because they couldnt fit inside the bore of the machine.
Higher levels of patient comfort. An MRI scanner is typically a lot less claustrophobic than a sun-bed. Considering traditional MRIs have a bore or opening of only 236 inches this might be concerning for someone with a larger build.
A middle ground between open MRIs and closed MRIs. Open MRI and closed MRI.
