As a medical professional, having diagnostic imaging systems are vital to addressing a range of minor-to-major health problems, such as tumors and severe injuries. This need is what makes MRI scanners necessary equipment. However, you may have heard the common trend among major hospitals and clinics opting for open MRI scanners instead of closed ones because of their flexibility for various patients.

Because open MRIs are not enclosed and require the patient to lie down, it can be easier to scan extremities more comprehensively as three-dimensional (3D) photos. The problem is it does have its significant drawbacks as compared to the more traditional closed units. To determine why you should opt for this type of scanner over open models, consider the following reasons: 


  • Produces higher quality 3D images

We mentioned earlier that some healthcare professionals would go for open MRIs since they can produce more in-depth 3D images. They are primarily clearer because you can see the affected area from various angles. The major issue is these scans are often not high resolution because standard open units only have a magnetic field strength that ranges from 0.3-0.7 Tesla. 

While you can find some higher resolutions from high-end open MRI that hit the 1.2-Tesla threshold, you will only get low-quality images, affecting your patient’s prognosis due to the lack of clear insights on the particular body parts. Additionally, most open MRI scanners can only focus on a fixed position, like just a leg or the arms. It means you may not see how the whole body responds to the problem area. 

With closed MRI units, you can utilize the significantly higher-powered magnetic activity to capture high-quality images. You can also scan the whole body, allowing you and your medical staff to assess the patient better, form a comprehensive diagnosis, and ensure more comprehensive treatment. As a result, you can build a positive reputation for your medical facility as you serve more individuals effectively. 


  • Initiate more intensive scans at a lesser time

Since you cannot get clear 3D photos with an open MRI scanner, you may have to use it more than once just to verify what you see. Your medical staff also has to spend more time interpreting data until an acceptable prognosis is formed. In effect, you can have patient backlogs, poor clinical workflow, and waste more money on costs for hospital or clinic operations. 

If you have a closed MRI scanner, you only need around 15-90 minutes per patient, enabling you and your support staff to work more efficiently, gather the 3D picture you need, and make an informed diagnosis for the area of concern. 

This benefit also helps patients in severe pain get the immediate help they need. However, if you are concerned about the tight space in the closed scanner, you may opt for other diagnostic imaging tools, such as X-rays and ultrasound. 


  • Gives more industry-standard options for support and unit selection 

Generally, you may have a harder time sourcing open MRI scanners if you use them as your main equipment for scanning. The technology is not as developed yet as closed MRI scanners, meaning only a few providers have open models. For this reason, plenty of medical facilities have both open and closed MRIs available to ensure work flexibility. You can just opt for closed scanners as your main imaging device and alternate with your open MRI when necessary. 

Additionally, take note that closed MRI systems have more developed maintenance capabilities. For instance, if you need MRI coil repairs, there is a seamless process ready for your unit. Replacement MRI parts for closed units are also in constant demand since a majority of medical professionals use them for their clinics and hospitals. Thus, they are still preferred over their open counterparts. 



While having open MRI scanners is becoming more prominent among various healthcare facilities, take note that closed units should not be overlooked. As the previously mentioned reasons illustrate, this type of system can be a valuable resource for your medical professionals as they treat various kinds of patients.
