![]() ![]() These X-rays are combined to form cross-sectional slices or even a 3-D model of your brain. MRIs display anatomic structure and fMRIs measure metabolic function.Ī computerized tomography (CT) scan is a series of X-ray images converted into cross-sectional images of your brain. It uses the magnetic field of the scanner to affect the magnetic nuclei of hydrogen atoms, so they can be measured and converted into images. These modern brain imaging techniques enable doctors to map out the regions and functions of your brain in a non-invasive way.įunctional magnetic resonance imaging (fMRI) can detect changes in blood flow and oxygen levels that result from your brain’s activity. ![]() It doesn’t require invasive steps and often simply involves laying down and being still while the scan takes place around you. One of the benefits of brain imaging is how easily it can be performed. ![]() functional near-infrared spectroscopy (fNIRS).electroencephalography (EEG) and magnetoencephalography (MEG).functional magnetic resonance imaging (fMRI).Since then, neuroimaging techniques have gotten increasingly more sophisticated, and are an important tool for neurology and mental health specialists.Ĭommonly used brain imaging techniques are: This early EEG was able to detect electrical waves in the brain that would rise and fall as different brain cells communicated with each other. The year 1924 marked the first human electroencephalography (EEG), recorded by German psychiatrist Hans Berger.
