Neuroimaging refers to a variety of medical techniques that can produce an image of the brain that your doctor can use to diagnose or treat many different types of brain conditions. Of these types of neuroimaging techniques, the most commonly used types are MRI, CT, and EEG tests, and depending on what your doctor is seeking to treat or diagnose you may be prescribed some or all of them or other similar types of neuroimaging. Learn more about what you can expect from neuroimaging tests by reaching out directly to your local experts at Winchester Neurological Consultants in Winchester, VA.

Electroencephalogram (EEG)

During an EEG test, you are either seated or told to lie down on a bed as electrodes are attached to your scalp. These electrodes are either individual discs that are attached to your scalp using a special paste or you are made to wear a cap that contains the electrodes.

Once recording has begun you'll be told to stay very still, but it is stopped periodically so you can relax and reposition.

The electrodes are used to measure your brainwaves, that is, the electric activity of your brain, which can be used to assess a number of brain disorders.

Computed Tomography (CT)

A CT scan is a computerized imaging procedure that uses x-rays to examine your brain, often used in the treatment of tumors, lesions, and injuries, among many other similar issues.

Contrast media is a substance that is introduced into your body to improve the results of CT scans, for brain scans you'll usually take the contrast media both orally and through an IV. If your doctor requires the use of contrast media then you'll be advised against eating prior to the treatment, you'll be given specific instructions about what to eat and when, or if you suffer from diabetes then the instructions will also vary.

You'll lie on a flat surface and be told not to move during the scan, you'll be in constant communication with your radiologist so you can notify them of any discomfort.

Magnetic Resonance Imaging (MRI)

Because an MRI uses magnetic fields to construct a three-dimensional image of your brain you'll be advised against wearing anything metallic and asked about anything metal in your body due to a medical procedure.

What you can expect is very similar to a CT scan, although you may not require a media contrast for some machines, it depends both on the equipment and what your doctor is trying to diagnose.
