Purpose: We have attempted to investigate whether a routine brain MRI study performed on a clinical whole-body 1.5 T scanner affects a following MEG examination. Material and Methods: Nine healthy volunteers (6 women, mean age 23 years, age range 20–27 years, 3 men, mean age 24 years, age range 23–25 years) underwent one MEG session before and two MEG sessions after MRI of the brain. The first MEG session (MEG1) was finished about 20 minutes before the MRI scans and the second MEG session (MEG2) was performed within 30 minutes after the MRI. The final MEG (MEG3) was performed two hours after MEG2. Each MEG sessi…
