Do you ever feel dizzy or lightheaded after getting an MRI? You’re not alone. Many people experience this side effect, but the good news is that it typically doesn’t last long. While the duration of dizziness can vary from person to person, it usually resolves itself within a few minutes to a couple of hours.
But why does this happen in the first place? The MRI machine uses powerful magnetic fields and radio waves to create detailed images of your body, which can cause your inner ear to become disoriented and lead to feelings of dizziness or vertigo. However, this is just a temporary side effect and nothing to worry about.
If you’re planning on getting an MRI soon, it’s important to know what to expect and how to prepare for the process. While dizziness can be a symptom, it’s not something that should deter you from getting the imaging studies you need. So, sit back, relax, and let’s delve into the world of MRI and dizziness.
Causes of dizziness during MRI
Many patients experience dizziness or vertigo during or after an MRI scan. This sensation may feel like the room is spinning or that the individual is off balance. There are several factors that can contribute to dizziness during an MRI, including:
- Motion sickness: Some people may experience motion sickness during an MRI scan due to the noise and vibrations of the machine. This can cause dizziness, nausea, and vomiting.
- Anxiety: MRI scans can be anxiety-inducing for some individuals, especially those who are claustrophobic or have had negative experiences in medical settings. Anxiety can trigger dizziness and other physical symptoms.
- Inner ear issues: Disorders of the inner ear, such as Meniere’s disease or benign paroxysmal positional vertigo (BPPV), can cause dizziness during an MRI. These conditions affect the balance and orientation systems of the body.
- Medications: Certain medications, such as anti-anxiety drugs or sedatives, can cause drowsiness and dizziness. If a patient takes such medications before an MRI, it may exacerbate these sensations during the procedure.
In some cases, dizziness during an MRI may be a sign of a more serious problem. For example, it may indicate a brain or inner ear abnormality that requires further evaluation. However, in the vast majority of cases, dizziness during an MRI is temporary and resolves on its own.

While an MRI machine is a vital tool for diagnosing various illnesses, many patients who undergo the procedure report experiencing dizziness afterwards. This side effect can range in severity, from mild discomfort to debilitating vertigo. The incidence of dizziness can vary depending on the type of MRI machine being used. Here, we compare the rates of dizziness reported in different MRI machines.
- Open MRI machines: Because open MRI machines have a more spacious design than traditional closed MRI machines, they often produce less claustrophobic feelings in patients. However, several studies have shown that open MRI machines are more likely to induce dizziness – up to 30% of patients have reported feeling dizzy during or after their open MRI procedure.
- Closed MRI machines: Patients undergoing MRI scans in a closed machine have to be completely still in a tight space, which can be a source of anxiety or discomfort for some. Nonetheless, patients who undergo MRIs in a closed machine tend to report dizziness at a lower rate than those who undergo MRIs in an open machine. In a study of 160 patients undergoing MRI scans, only about 2.5% reported experiencing dizziness.
- High-field MRI machines: High-field MRI machines are known for producing images of higher quality than low-field machines. However, they also produce stronger magnetic fields and noise levels, which can cause dizziness. In one study, 34% of patients undergoing an MRI in a high-field machine reported feeling dizzy afterwards.
It should be noted that every patient’s experience is unique, and the likelihood of dizziness varies depending on an array of factors, including medical history, body type, and the specifics of the MRI procedure.
In conclusion, the occurrence of dizziness after an MRI scan can be influenced by the type of machine used. While patients undergoing MRI scans in open machines often report feeling less claustrophobic, they may also experience higher rates of dizziness. Closed machines, on the other hand, may increase claustrophobic feelings but often induce less dizziness.
| MRI Machine Type | Reported Incidence of Dizziness |
|---|---|
| Open | 30% |
| Closed | 2.5% |
| High-field | 34% |
Ultimately, your doctor or healthcare provider should be able to assist you in deciding the best type of MRI machine for your specific needs.
