MEG-MRI Combined Brain Mapping

Researchers at Aalto University in Finland have developed the world’s most accurate device for mapping brain activity. Thanks to new low-field MRI, the device is the first to successfully combine the previously incompatible MRI and MEG (whole-head magnetoencephalography) technology. At only a few hundred-thousandths of the strength of magnetic fields used in traditional high-field MRI, the fields in new low-field MRI do not interfere with the fields used in MEG. The marriage of these...
