Open MRI machine Scan Preparation, Benefits

An open MRI is an imaging technique employing a machine with an open design on all sides, utilising magnets to capture internal body images. Unlike enclosed systems, this setup significantly reduces claustrophobia risk during the open MRI procedure, accommodating patients of diverse sizes. It serves as the primary option for some individuals requiring an open MRI scan due to its accommodating nature. However, its structure limits image capture in specific body regions, and the resultant images might have lower quality as the machine's magnetic strength is less compared to closed or wide-bore MRI systems. Hence, it is only sometimes suitable; specific scans demand a closed machine.

Open MRI Machine Look Like

An open MRI machine looks like a wide table with magnets on top and bottom, and it's open on all four sides. It's different from the closed MRI machines, which are like capsules. In an open MRI center, you can lie down on it comfortably without feeling stuck in a small space. This machine is excellent for people who feel scared in closed spaces. It's suitable for different body shapes and sizes, making it easier for patients during the imaging process compared to closed MRI machines.

Why does a doctor suggest an open MRI?

Doctors may recommend an open MRI based on several factors.

• Claustrophobia: Patients who experience fear or anxiety in enclosed spaces often find open MRIs more comfortable due to the lack of isolation, enabling a smoother imaging process.

• Physical limitations: Individuals with larger body sizes or mobility issues may find it easier to undergo imaging in open MRI machines as they offer more space and accessibility.

• Anxiety or panic disorders: Patients prone to panic attacks or heightened anxiety benefit from the openness of the machine, reducing stress during the procedure.

• Pediatric or elderly patients: Children and older adults may struggle with the enclosed nature of traditional MRI machines, making open MRIs a preferable option for a more relaxed experience.

• Specific body areas: In certain cases where imaging of particular body parts is essential, an open MRI might be the only viable option, despite potential compromises in image quality compared to closed systems.

Preparation before taking an Open MRI scan

Getting ready for an open MRI machine scan doesn't have to be complicated!

Here's a friendly guide to help you prepare comfortably for your appointment

• What to Wear: Put on loose, comfy clothes without any metal bits like zippers, buttons, or jewellery. If needed, the imaging centre might offer you a gown to wear during the scan. Remember, loose clothing makes it easier for you during the procedure.

• Metal Check: Before heading for your scan, take a quick check to ensure you're not carrying any metal items. Small things like jewellery, hairpins, or even clothing with metal parts (like zippers) can cause issues with the pictures the open MRI machine takes.

• Eating and Drinking: Sometimes, you should avoid eating or drinking for a few hours before your scan. This varies based on the type of scan you're having. It's crucial to follow any specific instructions provided by the healthcare team or the imaging center.

• Your Health Matters: Tell the healthcare provider if you have any health conditions, allergies, or metal implants like pacemakers. These things can affect how the scan works, so your team needs to know about them.

• Feeling Worried?: If you're anxious or worried about feeling claustrophobic during the open MRI scan, it's okay to talk about it with your healthcare provider. They might have some tips or medications to help you feel more relaxed.

Remember, these steps are there to make your open MRI machine scan as easy and stress-free as possible. By following these tips, you're setting yourself up for a successful and comfortable imaging experience.

Closed MRI vs Open MRI

Aspect	Closed MRI	Open MRI
Design	Enclosed capsule, limited space	Open on all sides, spacious layout
Claustrophobia	Higher risk due to confined space	Lower risk due to available design
Patient comfort	Potentially uncomfortable for some	More comfortable for diverse patients
Accessibility	Limited for larger or claustrophobic patients	More accessible for various body types
Imaging limitations	Superior image quality in many cases	Some limitations in specific body areas
Suitability	General imaging for most conditions	Alternative for certain conditions

Advantages of an open MRI test

• Comfortable Design: The open MRI machine is more spacious, reducing feelings of confinement and anxiety often associated with closed machines.

• Accessible for Various Body Types: Its open design accommodates individuals of diverse sizes and shapes, making it more inclusive and comfortable for a broader range of patients.

• Reduced Claustrophobia: Compared to enclosed machines, the open structure significantly lowers the risk of claustrophobia, ensuring a more relaxed experience during the test.

• Pediatric and Elderly-Friendly: Particularly beneficial for children and older adults who may find the open environment less intimidating compared to closed machines.

• Alternative Imaging Solution: It serves as a viable alternative for certain conditions where closed MRI tests might not be suitable, ensuring patients can undergo necessary imaging comfortably.

Frequently Asked Questions

1. What exactly is an open MRI?

An open MRI is a type of MRI machine with an open design, offering more space and reducing feelings of confinement compared to traditional closed MRI machines.

2. What is an open-system MRI?

An open system MRI refers to an MRI machine with an open design, providing a more spacious and less enclosed environment for patients during imaging.

3. Is open MRI less claustrophobic?

Yes, open MRIs are generally less claustrophobic compared to closed MRI machines due to their more open design.

4. Which MRI is better, open or closed?

It depends on individual needs. Closed MRIs often provide higher image quality, but open MRIs are better for patients who experience claustrophobia or need more space.

5. How long does an open MRI take?

The duration of an open MRI scan varies based on the type of imaging required, but it typically takes between 15 minutes to an hour.

6. Is an open MRI good for the brain?

Yes, open MRIs can be used for brain imaging. They offer an alternative for individuals who might find closed machines uncomfortable.
