Five Benefits of an Open MRI



A closed cylindrical MRI scanner provides crisp images in the right situation. There are also situations when an open MRI system can produce the same or superior images when a closed system is not a viable option. Whether your facility is purchasing its first MRI scanner or replacing its existing medical imaging equipment, a Hitachi open MRI can provide several advantages. Here are just five of the many benefits that an open MRI has to offer over closed scanners.

1. Less Expensive - An open-system scanner is generally less expensive than a closed-bore scanner because the design is simpler, cryogen-free and more compact. The engineering, installation and transportation costs for an open MRI are usually less expensive as well. A facility can reduce its cost further by purchasing a certified previously owned MRI scanner instead of buying a new piece of equipment.

2. Lower Maintenance Costs - Another advantage of open systems is that they typically have lower maintenance costs because the devices have fixed magnets. Closed scanners often require considerable routine maintenance and service, such as monitoring and filling the cryogen system, replacing the cold head and maintaining the chiller. As a result, the maintenance costs associated with an open MRI scanner can be as much as 50 percent less than a closed MRI scanner.

3. Less Noisy - Open MRI scanners are quieter than closed scanners. Loud noises generated by a closed system can make patients uncomfortable. In some cases, the noise can damage hearing, which means that the patient must wear earplugs to protect their hearing during the examination. This precaution is not required with an open scanner. Some patients may have metallic implants from a previous surgical procedure that can reduce the quality of the image generated by a closed scanner. The lower field strength of an open MRI scanner produces less distortion. The changing magnetic fields of a closed MRI can also generate heat within the metal implants as well as the ink of a tattoo, which may cause patient discomfort. The design and lower magnetic field strength of an open MRI typically prevents this thermal effect.

4. Greater Accuracy - The open design also enables critical body parts to be positioned near the center of the magnet for greater accuracy. This can eliminate the need to use chemical contrasting agents. The image is also less likely to be distorted by a patient’s movement. The configuration of a closed MRI does not necessarily allow all body parts to be in the best position possible. Some open-system MRI models offer higher field strength for greater contrast between various types of body tissue, which can make it easier to provide an accurate diagnosis.

5. Ability to Increase Patient Volume - An open system can increase patient volume because it can accommodate existing patients as well as those unable to use a closed scanner. These include individuals who may become claustrophobic inside a closed MRI and patients who are too large to fit inside the equipment. The open sides of the scanner enable the patient to see around the room and receive reassurance from family, friends and medical staff during the examination. As a result, the open system improves the patient’s quality of care. Improving patient care and comfort provides the opportunity to gain more referrals for your medical facility than it previously received, which increases your visibility. An increase in scan volume can lead to the organic business growth of your practice.
