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 MRI is more comfortable and easier to tolerate than traditional closed machines. Open MRIs have a clear view of the scan area, making them ideal for certain types of scans, such as brain scans.
How long does the test take? 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.

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.
Most people who have claustrophobia are able to tolerate the MRI scan in the open, upright MRI machine. This is the structure of most MRI machines that can only perform the imaging studies with the patient lying on their back on a table that is moved into the core of the magnetic field where the images are captured.
When not properly accommodated during an MRI, claustrophobic patients may experience panic attacks, which can bring on increased heart rate, difficulty breathing, chills, sweating, and other distressing symptoms.
Not intentionally. Many of our examinations require your cooperation and ability to follow commands to hold your breath to produce the images required to make a diagnosis. For those examinations, we will not allow you to fall asleep.
A magnetic resonance imaging (MRI) scan is a painless procedure that lasts 15 to 90 minutes, depending on the size of the area being scanned and the number of images being taken.
Doctors often scan only certain areas of the body, like the brain or the general location of the organ in question. A whole-body scan may be requested if needed. So, the typical MRI scan should take 15-90 minutes.
Many MRI procedures don't require your head to go inside the machine at all, but if you need a head or upper spine MRI, you'll appreciate the fact our machine provides a full 12 inches of clearance between your face and the wall – relieving stress for our patients with claustrophobia.
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.
MRI shows structural similarities and differences in the brains of people with depression and social anxiety. Many of these individuals show changes to the cortex. MDD and SAD patients show common gray matter abnormalities in brain networks that govern attention.
Keep your eyes closed or even wear a blindfold.
It's much easier in an open MRI it's wider than a standard scanner, so patients shouldn't feel any walls touching them.
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.
We understand that the examination can be a bit stressful, but there is no reason to fear the MRI machine. Having an MRI is a painless, completely safe procedure. You'll be much less anxious if you know exactly what to expect, and this guide will walk you through the steps of a typical MRI scan.
Before the MRI
You may take all medicines. You may eat and drink unless you are having an MRCP, a specific exam for your gallbladder.
Please wear comfortable clothing. Cotton, polyester, and wool are best. Don't worry about the snaps or zippers on pants, as that metal can be allowed into the scanning facility. If you have questions about these procedures, please feel free to contact the study coordinator.
The scan typically takes about 30 to 60 minutes. According to Cincinnati Children's Hospital and Medical Center, scans that don't require a contrast dye are generally shorter and may only take 30 to 45 minutes. Some procedures like the limited brain MRI only take about 5 minutes.
