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.
Instead of a tube, an open MRI has scanners on the sides with an opening on top, making it an outstanding option for those who have claustrophobia. The patient lays comfortably on a platform while the scanners on the sides do all the work.
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.
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.
Patients with certain conditions that may prevent them from staying still in the MRI machine, such as claustrophobia, anxiety, or a condition that causes physical pain, may have an MRI with anesthesia. It is also common for children to have an MRI with anesthesia, since it is often difficult for them to remain still.
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.
Versed (generically known as midazolam) and fentanyl are two medications commonly used in conjunction to alleviate pain, aid relaxation, and reduce a patient's memory of the procedure.
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.
Anesthesia may be required to ensure the immobility of the patient during a magnetic resonance imaging (MRI) scan, particularly in pediatric patients. An MRI scanner generates radiofrequency radiation (RFR) to obtain images of parts of the body.
Depending on what needs to be scanned, your test will take between 20 to 90 minutes.
An open-bore MRI machine is open on both ends and enclosed by a tube-like bore; it offers a wide opening of approximately two feet. A conventional MRI is also open on both ends but has a smaller opening.
Diazepam 5 mg po, once for MRI study or Lorazepam 1mg po, once for MRI study. B. For use with adult patients who have a need for an oral sedative for a successful MRI.
Gadobenate is a gadolinium-based contrast agent (GBCA). Gadobenate is given by injection before an MRI scan to help find problems in the brain, spine, and other parts of your body.
Background: Magnetic Resonance Imaging (MRI) is associated with high levels of anxiety in many patients which may interfere with image quality and increase examination time.
Since the MRI machines are magnets, it is best to not apply deodorants, antiperspirants, perfumes, or body lotions before the examination. These items contain metals that might interfere with the magnetic field inside the MRI machine and cause you to have distorted images and wrong results.
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.
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.
A single scan may take a few seconds or 3 to 8 minutes. You may be asked to hold your breath during short scans. The total scan lasts 15 to 90 minutes, depending on the size of the area being scanned and how many images are needed. You'll be moved out of the scanner when your scan is over.
It's common to use a combination of Versed (a benzodiazepine) and Fentanyl, an opioid medication commonly prescribed for pain and sedation. You must have a physical and medical history within 30 days prior to your MRI in order to ensure the safety of these medications.
It's important that patients remove all clothing prior to their MRI exam. We ask patients to remove: All outer clothing, including shoes. Bras or any undergarment that could have metal in it.
Your whole body does not go in the machine, only the half or part that needs to be scanned. One thing you'll need to know is that the machine is noisy. It makes a lot of different noises, and some of them are extremely loud. Some patients say it sounds like a sledgehammer.
The most accurate MRI system is the closed MRI scan. You lie in a tube-like, narrow space structure for the scan. Patients often report feelings of claustrophobia while being scanned in a traditional closed MRI. Being obese can make it almost impossible to undergo a closed scan.
The time required for a scan depends on various factors, including the type of scan being performed and the patient's size. However, open MRI scans may take a little longer than closed ones since the magnets must be in place longer.
