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.
Reactions can include anything from mild anxiety to all out panic attacks and hyperventilating. More to the point, researchers in one study found that as many as 13% of all patients who received an MRI (Magnetic Resonance Imaging), reported feelings of panic and or anxiety during their MRI.
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.
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.
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.
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.
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.
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.
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.
Oral Benzodiazepines
Many patients find that an oral benzodiazepine, such as Xanax, Ativan, or Valium, taken prior to the exam sufficiently relieves their anxiety and allows them to complete an MRI with relative ease.
People often make up scary images in their head and start picturing the MRI machine as a claustrophobic trap that they won't be able to handle. You might feel more comfortable when you see an Open MRI. The imaging center often allows patients to have a tour of the room where the MRIs are conducted.
Fear of enclosed spaces, or claustrophobia: “This is the biggest reason that people have fear and anxiety and even avoiding having an MRI,” Sullivan said. Patients expect all MRIs to involve being inserted in an enclosed “tube,” but an open MRI uses a device positioned above a table that is open on all sides.
Another factor that causes anxiety in patients is MRI procedures. The loud noise, fear of pain, the experience of losing control, the long duration of the examination andenclosed environment of the MR tunnel is known to induce anxiety in patients [6].
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.
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.
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.
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.
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.
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.
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.
MRI is also contraindicated in the presence of internal metallic objects such as bullets or shrapnel, as well as surgical clips, pins, plates, screws, metal sutures, or wire mesh. If you are pregnant or suspect that you may be pregnant, you should notify your physician.
Approximately 10 % of people who attempt an MRI are unable to complete it because of claustrophobia.
In a new study published in Current Biology online on Sept. 22, a team led by Johns Hopkins scientists suggests that MRI's strong magnet pushes on fluid that circulates in the inner ear's balance center, leading to a feeling of unexpected or unsteady movement.
