YR 2022 UL http://www.ajnr.org/content/43/12/E46.abstract AB SUMMARY: Magnetoencephalography, the extracranial detection of tiny magnetic fields emanating from intracranial electrical activity of neurons, and its source modeling relation, magnetic source imaging, represent a powerful functional neuroimaging technique, able to detect and localize both spontaneous and evoked activity of the brain in health and disease. Recent years have seen an increased utilization of this technique for both clinical practice and research, in the United States and worldwide. This report summarizes current thinking, presents recommendations for clinical implementation, and offers an outlook for emerging new clinical indications.ACRAmerican College of RadiologyADAlzheimer diseaseASDautism spectrum disorderCMSCenters for Medicare and Medicaid ServicesCPTCurrent Procedural TerminologyECDequivalent current dipoleiEEGintracranial electroencephalographyMEGmagnetoencephalographyMSImagnetic source imaging
