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.
Many clinicians agree that anxiety causes movement artifact and incomplete processing during the MRI [15,16,17]. Prolonged and repeated MRI procedure result in decrease in the diagnostic value of MRI and deterioration of image quality.
As for the impact on MRI workflow, patient stress and anxiety were found to significantly predict the probability of scan repetitions (Nagelkerke's R2 = 0.31, p = 0.011) and the length of scan (adjusted R2 = 0.22, p < 0.001).
Unless you're having an fMRI, any brain scans from traditional MRIs will only show structural elements. So, even if you feel a brief spike of stress in the beginning of your MRI before you start to relax, medical staff won't have access to any insights into your thoughts or feelings.
If you are having an MRI scan that does not require you to follow commands, you may be allowed to fall asleep. You should clarify this with your radiologist before the procedure begins.
They will position a coil over the part of your body that's going to be imaged. They will then slide you on the couch into the magnet. The radiographers will issue you with ear protection (ear defenders) before helping you into the scanner. You will also get a panic button to use in an emergency.
IMPORTANT NOTE: DO NOT TAKE your medication until you arrive for the MRI and the technologist has told you to do so. We need to ensure you are properly screened and that we are running on time before you take the medication.
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.
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.

Functional MRI studies on patients with major depression demonstrated abnormal excitations and inhibitions in the prefrontal cortex also known as the connectome - the network of neural connections within the brain. This part of the brain governs cognitive ability and emotions.
Brain scans alone cannot be used to diagnose a mental disorder, such as autism, anxiety, depression, schizophrenia, or bipolar disorder. In some cases, a brain scan might be used to rule out other medical illnesses, such as a tumor, that could cause symptoms similar to a mental disorder, such as depression.
Conclusion. MRIs and related technology are becoming increasingly adept at diagnosing mental illness. Currently, magnetic resonance imaging can play an important role alongside the observations of physicians and other mental health care professionals.
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.
If you are taking aspirin or other NSAIDS (non-steroidal anti-inflammatory drugs) like Motrin, Aleve, or Naprosyn, stop taking it 3 days before your appointment, with your prescribing physician's approval. If you take medication for high blood pressure, please do NOT miss a dose, take as prescribed.
Radiologists recommend fasting prior to undergoing a CT or MRI with contrast because of the possible side effects of the contrast agents. While rare, side effects of contrast can cause nausea or vomiting during the test. Vomiting while lying down could cause food blockages in your airway, known as asphyxia.
The Radiologist will send a report to the doctor who arranged the scan. They'll discuss the results with you. It usually takes 1 to 2 weeks for the results of an MRI scan to come through, unless they're needed urgently.
Another concern for people undergoing MRI testing is claustrophobia, or the fear associated with being in a small or enclosed space. If you experience claustrophobia or anxiety-induced panic attacks from being in tight spaces, you are not alone. An estimated 7–10% of the population lives with this condition.
You can have your eyes open during the scan, although some patients find that closing their eyes or putting a washcloth over them helps keep their nerves calm. If you close your eyes, though, please be sure not to fall asleep. While you sleep, your body can twitch and move, ruining the MR images being taken.
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.
If you need to cough or get an itch, tell them and they can get you out, or give you a short break between sequences. Then you are moved out of the machine, released, have your plastic tube removed and can go home.
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.
