Being strapped, unable to move, combined with the weird noises and daunting lights — going through an MRI machine can trigger full-blown panic attacks. According to various studies, this phenomenon can be classified as MRI phobia. The fear of going inside an MRI machine can be classified as MRI phobia.
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.
Fear of MRI is extremely common and tunnel MRI scanners can be particularly triggering and traumatic, as patients must lie still in a tunnel for between 15 and 90 minutes. Some patients even need sedation to stay calm enough to get through the experience.
Magnetic resonance imaging (MRI) has become one of the most important diagnostic tools in many areas of medicine. Several studies have shown that MRI causes severe anxiety in 37% of patients, even those who state that they are not claustrophobic, and 5–10% cannot complete MRI due to claustrophobia [7].
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.
Generally, MRIs under anesthesia are performed under sedation, although sometimes they are performed under general anesthesia. Sedation is characterized as being in a state between relaxed and very sleepy, but not quite unconscious.
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.
Any movement by the person during the scanning process causes blurring of the images. The combination of the closed environment and the noise make it uncomfortable for some patients, especially if they are claustrophobic.
There aren't any side-effects from the MRI scan itself. However, if you've had an injection of contrast medium (dye) as part of the investigation, you may have some side-effects which might include a skin rash, dizziness, a headache, and nausea.
Today, when it comes to getting an MRI, that innate reaction is considerably less helpful if your doctor says you need a scan to guide your treatment. The escape reaction leads some people to crawl right out the end of an MRI machine during the middle of an exam.
Contrast agents
Some MRI scans involve having an injection of a contrast agent. This makes certain tissues and blood vessels show up more clearly and in greater detail. Sometimes the contrast agent can cause side effects, like: feeling or being sick.
Loose metal objects can injure you during an MRI when they're pulled toward the very powerful MRI magnet. This means all jewelry has to come off, not only what you can see, and this includes belly-button or toe rings. 5.
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.
Can a subject wear deodorant for an MRI scan? It is recommended to refrain from wearing any powder, perfumes, deodorant and/or lotions on your underarms and chest area prior to the procedure. This is to prevent the possibility of localized burns because these items may have metal in them.
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.
You must lie very still during the scan. If you move, the MRI scan pictures may not be clear. Your primary care physician may order you a mild sedative if you are claustrophobic (afraid of closed spaces), have a hard time staying still, or have chronic pain.
Sedation for diagnostic services conjures up images of pain and discomfort. MRI sedation is used during an MRI for patients who cannot remain still in the scanner due to problems such as anxiety, claustrophobia, or a condition that causes physical discomfort.
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.
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.
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. Claustrophobia is a very common condition, affecting as much as 5% of the population.
In most cases, a family member or friend may enter the MRI room with you and stay with you throughout your exam. If the situation allows, they may even hold your hand or pat you on the knees so that you know that they are there with you.
The position of body parts in the magnetic field distorts it. So if you cross your legs, scratch your head, open your mouth, yawn (inhale deeply), or shift your posture, it can lead to artifacts even if your brain doesn't move.
