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.
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.
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.
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.
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.
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.
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.
What medications are used? Propofol will be given through an I.V. to induce sleep. This medication has a short duration of action and a rapid recovery time and is administered to make sure you remain asleep during the entire MRI study.
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.
9 Diazepam is often given to a patient for premedication in MRI.
Of the 54 clinical patients, 31 were given IV diazepam (mean dose, 7.5 mg; range, 2.5-20 mg) with successful scanning in 30 (97%).
They are less enclosed than a closed MRI: An open MRI system doesn't cause the same level of claustrophobia and anxiety as a closed MRI system, since the unit doesn't fully encase your body. The system can accommodate you much more comfortably, no matter what size you are.
Depending on what needs to be scanned, your test will take between 20 to 90 minutes.
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.
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.
Providence radiology experts recommend cotton clothing or hospital gowns to keep patients safe and comfortable during their procedure.
You will not be able to have breakfast the morning of your surgery. You can brush your teeth in the morning, just be sure to spit the water out!
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.
If You Have an Overactive Bladder
This feeling of urgency can make it harder to hold urine in. While you may still experience this urgency to a degree, not drinking for several hours before your procedure can make you less likely to experience incontinence during the scan.
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.
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.
It's important not to drink a lot of caffeine before your MRI because caffeine will make your blood vessels constrict. If your scan is monitoring blood flow, constricted blood vessels will give you inaccurate results.
