An open-bore MRI machine is bigger and roomier. For a claustrophobic patient who needs a head scan, this means the machine is going to be 10 cm further away from their face -- a big difference!
People who are claustrophobic may fare better with open MRI machines. It is also more comfortable for very overweight or obese patients. The high-field open MRI offers more space and more airflow for greater comfort. Open MRI machines have wider openings and are less confining.
The test usually takes 30 to 60 minutes but can take as long as 2 hours.
Both open or closed MRIs can provide accurate results. However, due to its design, in some cases an open MRI is not able to take images of certain areas of the body. Also, the images that are captured may be of lesser quality of that of a closed MRI. For this reason, certain scans must be taken with a closed MRI.
You can keep your eyes closed.
Some people (including me) just close their eyes before they're inserted into the tube and keep them closed throughout the test.
Talk with your doctor about your claustrophobia and ask for a sedative to help. These sedatives may make you sleepy and often people will fall asleep during the MRI. Make sure you inform the staff that you have taken a sedative so they are aware and make certain you have a driver.
Some techniques that can reduce the anxiety that comes with feelings of claustrophobia include focused breathing and covering your eyes with a towel during the exam. RAYUS also offers headphones for listening to music and, for Open Upright MRI patients, watching TV is an option.
Since the open MRI system only uses magnets above and below you and not on all sides, it takes longer for the technologist to scan the targeted area, meaning it doesn't produce full images.
An Open Upright MRI scanner is an alternative for patients who are claustrophobic, cannot lie down due to pain, or whose size prevents them from being evaluated in a traditional MRI scanner. During the scan you can stand or sit, with an unobstructed view forward — you can even watch TV during most exams.
You will lie down on a table that slides into the MRI machine. The table slides through a large magnet shaped like a tube. You may have a plastic coil placed around your head. After the table slides into the machine, a technician will take several pictures of your brain, each of which will take a few minutes.
The technologist will ask you several times to hold your breath and stay still to be able to get good pictures. You will be asked each time to hold your breath for twenty seconds. This part is very important because we cannot do the MRI examination, if you cannot hold your breath long enough.
A head MRI and a brain MRI are the same procedure. They both provide images of the inside of your head. While healthcare providers most often use head and brain MRIs to assess your brain, these imaging procedures provide images of other structures in your head, too, such as facial bones, blood vessels and nerves.
The space where the patient lies is much wider than a fixed MRI and most of the time their head will be outside of the machine during the scan. Here at Derry Imaging, we have two machines available, a traditional MRI and a “Wide Bore” Open MRI.
For patients who may experience claustrophobia during an MRI scan and require prophylaxis, the University of Wisconsin Department of Radiology suggests the use of Lorazepam (Ativan, Temesta), a short-to-intermediate duration benzodiazepine.
The open, upright MRI machine is much better tolerated by patients who are claustrophobic. The scans can be performed with the patient sitting, lying down, or standing. People can watch television while the scans are performed. The unit is open in the front, back, and top.
That's because open MRI scanners are much quieter than traditional scanners. Open MRIs produce less noise, and since they don't have an enclosed tunnel or walls, the acoustics are not as intense while having a scan.
An MRI scanner is a short cylinder that's open at both ends. You'll lie on a motorised bed that's moved inside the scanner. You'll enter the scanner either head first or feet first, depending on the part of your body being scanned.
An abdominal MRI generally takes about 30 to 90 minutes. In some cases, it may take up to about 2 hours. Abdominal MRIs are used for a variety of reasons, such as examining: blood flow.

You will be asked to remove any clothing containing metal and all jewelry. You will be provided metal free clothing to change into such as gown, shorts or pants. Lockers are available to safely store all personal items such as wallet, purse, keys, phone and other electronic devices.
RAYUS Center Manager Desiree Rocovich says claustrophobia is common in the world of MRI. It's so common that asking questions about it is standard in the pre-appointment screening call. “Four out of ten patients that we call will mention something about claustrophobia,” Desiree estimates.
The Upright MRI is the only MRI scanner that can image patients in any position, whether it's sitting, standing, bending or lying down. This allows it to image any part of the body. All other MRIs can only scan patients while laying down.
During an MRI, you should use this same method that is used in yoga classes. Take slow, deep breaths to ensure that you are breathing well. If it helps, count to 10 as you breathe in and out, and then gradually slow it down from there. Slow breathing will ensure a calm and relaxed state of mind.
Counting numbers or listening to music: Counting slowly or listening to a soothing melody can help distract you and make the time pass quickly while you are in the scanner. Talk to the Technician: In most instances, you can speak to the technician throughout most of the procedure.
