Evaluation of Different Brain Imaging Technologies

Abstract

To detect disorders caused by various brain regions impaired, many neuroimaging techniques are routinely utilized, such as electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) that may be the most common imaging techniques used to detect. This article summarizes and discusses the benefits and drawbacks of different neuroimaging techniques, as well as the benefits and limitations of some combined imaging techniques to have a clearer perception of neuroimaging technologies. In addition, this paper will also specifically focus on fNIRS and EGG-MEG combining techniques. The result shows that EEG has a high temporal resolution and fMRI has a high spatial resolution, so EEG and fMRI are generally combined to diagnosis particular disorders. A key point is that the combined use of EEG and fMRI may lead to inaccurate results. The EGG-MEG provides a new direction for the continuous treatment of epilepsy or other brain diseases.
